The card is free and takes ten minutes

An SFPL card is free to anyone who lives, works, goes to school, or owns property in San Francisco. You can sign up online in a few minutes and start using the digital services immediately, before you even pick up the physical card. That one card is the key to everything below.

Kanopy: free movies, no ads

Kanopy is the big one. It is a real streaming service, arthouse films, documentaries, foreign cinema, the Criterion Collection, plenty of mainstream titles, and your library card unlocks it for free. No ads, no upsell. SFPL gives you a set number of plays each month, which refreshes, and it is more than enough unless you are watching a film every single night. This is the service that quietly makes a movie-streaming subscription optional.

Hoopla: movies, shows, audiobooks, comics, music

Hoopla is the everything app. Movies and TV, yes, but also audiobooks, ebooks, comics, and full albums. You get a set number of borrows per month, and each borrow covers a whole movie, a whole audiobook, or a whole album. Between Hoopla and Kanopy, the “what do we watch tonight” problem is solved without a single paid subscription.

Libby: ebooks and audiobooks, the Audible killer

Libby (the OverDrive app) is how you cancel Audible and stop buying ebooks. It borrows straight from the library’s digital collection to your phone or e-reader. Popular titles have a hold line, same as a physical book, so you queue up a few and they show up over the coming weeks. If you read or listen even a little, this one alone pays for the whole strategy.

The bonus: free museum passes and learning

Two things people miss. SFPL’s Discover and Go program gets you free or discounted passes to local museums, which turns a pricey weekend into a free one. And your card usually unlocks LinkedIn Learning and other course libraries for free, so the skills-course subscription goes in the bin too.

The math

Here is what a card that costs nothing quietly cancels:

• Video streaming: roughly $18 to $23 a month, replaced by Kanopy and Hoopla.
• Audiobooks: an Audible membership is about $15 a month, replaced by Libby and Hoopla.
• Ebooks: whatever you spend buying them, replaced by Libby.
• A learning subscription: often $20 to $40 a month, replaced by LinkedIn Learning through the library.

That is easily $50 or more a month, six hundred dollars a year, for a card that is free. You will not replace literally every service, the newest prestige show on one specific platform will still be walled off, but you replace most of it, and you stop paying a subscription for the nights you would have watched an old movie anyway.

The move

Get the card online today. Install Kanopy, Hoopla, and Libby, and sign in with your card number. Then look hard at your subscriptions and cancel the ones the library now covers. Keep the one service you genuinely cannot live without, if any, and let the library handle the rest.

The library is the most underused frugal resource in the city, a free service your taxes already paid for. Use it. More of the same thinking is in Frugal SF, including the one that saves the most, rent control.

The math that should scare you into staying

Two years ago I signed at $1,680. Since then, market rent for my exact unit has climbed to roughly $3,400 to $3,800. My rent went up only by the small amount the city allows each year, so I am still sitting around $1,680. Do the arithmetic: staying put saves me somewhere between $1,700 and $2,100 every month. That is north of $20,000 a year, tax-free, for the act of not moving. There is no side hustle in this city with that hourly rate.

How it actually works

• It covers older buildings. SF rent control applies to most multi-unit buildings with a certificate of occupancy before June 13, 1979. Single-family homes, condos, and new construction are generally exempt from the price cap (though some eviction protections still apply).
• The annual increase is capped and tiny. The SF Rent Board sets an allowable increase each year, tied to inflation, and it is small, usually low single digits. Meanwhile market rents jump 10, 20, 30 percent in a hot year. Your controlled rent creeps up while the market sprints.
• The gap compounds. Every year the market outruns your cap, the spread widens. That is why you meet people in this city paying a fraction of what their next-door neighbor pays for an identical unit.

Costa-Hawkins, or why you never move out

Here is the part that turns rent control from “nice discount” into “never leave under any circumstances”: vacancy decontrol. Under California’s Costa-Hawkins law, the moment a rent-controlled unit becomes vacant, the landlord can reset the rent to whatever the market will bear. The cap protects the tenancy, not the apartment. Your discount exists only as long as you stay in it. Walk away and it vanishes instantly, and the next tenant starts at $3,800.

This is why in San Francisco you meet people paying $900 for a place that would list at $3,500. They are not lucky. They are just not foolish enough to move for a nicer kitchen.

What this means for you

• Treat a controlled unit like the asset it is. Do not move for a slightly better view or an in-unit washer. The washer is not worth $20,000 a year.
• Hunt for pre-1979 multi-unit buildings. Older, bigger buildings are where the protection lives. Check the year built before you fall in love with a place.
• Know your protections. Just-cause eviction rules mean a landlord generally cannot remove you without a specific legal reason. The main legitimate exits they have, like owner move-in or the Ellis Act, come with their own rules and, often, payouts to you.
• Be an easy tenant. Pay on time, keep records, do not give anyone a reason. Your leverage is that you are far cheaper to keep than to fight.

The uncomfortable truth

Rent control is the single biggest reason I can live in one of the most expensive cities on the planet without a matching salary. It is worth more than almost any raise I could chase. And a lot of the people who complain that SF is unaffordable are the same people who hop apartments every two years chasing amenities, resetting their rent to market each time they move.

Find the controlled unit. Get in. Stay put. In this city, boring beats broke, and staying still is the highest-paying thing you can do.

That is the biggest lever, but it is one of many. The rest of how I live well here for cheap is in Frugal SF, starting with eating for free on the tech-event circuit.

The calendar: Luma

The single best tool is Luma (lu.ma). It is where the SF tech scene posts events. You can browse by night, filter for what is near you, and RSVP in two taps. Skim the descriptions for the magic words: “food and drinks provided,” “dinner served,” “catered,” “happy hour.” Those events are dinner. RSVP to a couple each week and you have a rotating meal plan that also happens to be full of interesting people.

Back it up with the other feeds: Meetup, Eventbrite, Partiful invites if you are in the right group chats, and the Slack and Discord communities that announce launches and demo nights.

The unwritten rules (be a guest, not a mooch)

This works because these events genuinely want attendees. You are supplying demand: a warm body, a question during Q&A, someone who makes the room look full for the host’s photos. So behave like a real guest and it stays a fair trade.

• RSVP honestly and actually show up. No-shows wreck the host’s catering count.
• Talk to at least one person. Ask what they are building. This is the actual point. The food is the bonus, and the connections are worth far more than the catering.
• Do not plate-and-bolt. Showing up, loading a plate, and leaving is how you earn a reputation in a surprisingly small scene. Stay, engage, be a person.

Do that and you are not freeloading. You are participating in exactly the thing the host paid for: a room full of interested people.

Conferences: the free-pass side door

Big conferences cost a fortune, but two things are usually true. Most have a free expo or exhibit hall pass, and the real food is at the open side events. Around any major conference, sponsors throw mixers, afterparties, and launch dinners, and a lot of them are open to anyone who registers, no full ticket required.

The move: watch the conference’s side-event calendar (often posted on Luma), grab the free expo pass, and hit the open evening events. You get the networking and the spread without the four-figure badge. Stick to the genuinely open events, the ones asking you to register rather than the ones behind the paid wall, and you are a guest, not a gatecrasher.

Why this is a real strategy, not a gimmick

Food is one of the top three expenses for anyone living here. Knocking two or three dinners a week off your grocery bill is real money, hundreds a month, and you are trading it for time spent doing something useful anyway: meeting people in your field, hearing what is being built, occasionally stumbling into a job, a client, or a cofounder. The free food is the city paying you to network.

A weeknight template

• Monday: skim Luma for the week, RSVP to two or three events that mention food.
• Tuesday and Thursday: go. Eat, talk to three people, leave with a contact or two.
• Weekends: hackathons are catered start to finish, and they pay cash on top of the food.

San Francisco is brutally expensive, but it is also stuffed with companies desperate to get you into a room. Let them. Show up, be useful, eat well.

More of how I live well here for less is in Frugal SF, including the one that saves the most: rent control.

The prices, side by side

• Uber or Lyft: $40 to $70 depending on surge. For one person going to the airport, that is genuinely unhinged.
• BART from SF to SFO: around $10 to $11 one way, because BART tacks a special premium onto the SFO station on top of the normal fare. You also haul your bag through downtown, wait, and pay tourist rates for the privilege.
• SamTrans bus: $2.05. It goes to the airport. It stops at the terminal. That is the whole story.

Same destination. One option costs five times more and lets you feel clever for “taking transit.”

Why BART sucks for this

BART’s SFO fare is expensive on purpose. The airport premium exists because tourists will pay anything to reach a plane, and the agency knows it. You are not a tourist. You live here. Paying the BART airport surcharge when a two-dollar bus goes to the same curb is just donating money to a transit district out of pure habit. BART has its uses. Getting you to SFO cheaply is not one of them.

The SamTrans move

SamTrans runs buses down the Peninsula that serve SFO directly. Depending on where you are, a route will drop you right at the airport for the local fare, which is a couple of dollars ($2.05 when I ride it). Pull up the SamTrans site, find the route and schedule from your neighborhood, note which terminal it stops at, and that is your airport ride, sorted, for the price of a coffee.

The one honest tradeoff: a bus is slower than a train and runs less often, so you check the schedule and leave a little earlier. To save anywhere from eight to sixty dollars on every airport trip, I will happily leave twenty minutes earlier. That is a fantastic hourly rate for the mild inconvenience of reading a bus schedule.

When it is worth it (almost always)

• Carry-on or light bag: SamTrans, every single time.
• Odd hours or a mountain of luggage: fine, sometimes a shared ride makes sense. Use judgment.
• A normal trip out of SFO: the bus is the answer, and the people paying $60 for an Uber to save twenty-five minutes are the entire reason ride-share is a business.

The frugal life is a thousand small decisions like this one. “Take BART to the airport” is the default, and the default is a tax on not thinking about it. Take the bus, keep the money, and let the tourists prop up the surcharge.

This is one of many. The rest of living well in SF for cheap is in Frugal SF, starting with the biggest lever of all, rent control.

Darn Tough socks: a real lifetime warranty

Darn Tough makes merino wool socks in Vermont with an unconditional lifetime warranty. Not “lifetime against manufacturing defects.” Unconditional. You wear a hole in them, any hole, any reason, you send them back and get a new pair free, no receipt required. I own a handful of pairs. When one finally wears through, I warranty it. My sock budget is, functionally, zero for the rest of my life after the first buy-in.

Yes, a pair runs around $25 versus $2 for a cheap multipack. But cheap socks die in months and you rebuy them forever. Darn Tough is one purchase that never repeats. Over ten years the math is not remotely close, and your feet are happier the whole time.

Patagonia: the deep one

Patagonia is the other pillar, and its warranty is deep enough that I gave it a whole article of its own: Patagonia’s warranty, what actually works. The short version: buy one genuinely good piece used or on sale, then keep it alive through Patagonia’s repair pipeline for years. Most repairs come back free, US stores ship the fixed item back to you free, and one maintained shell outlasts a closet of disposable jackets. The full playbook, including the things nobody tells you, is in that article.

The buy-it-for-life mindset

The principle generalizes. For the handful of things you use constantly, socks, an outer layer, a bag, boots, a good pan, buy the version with a genuine lifetime warranty or a real repair program, pay once, and stop thinking about it. It feels expensive at the register and it is the cheapest path over any timeframe that matters.

The trap is treating clothes as disposable. Every $12 item you rebuy twice a year is more expensive than the $30 one you buy once. Frugality is not buying the cheapest thing on the shelf. It is buying the last thing, the one you never have to replace.

What to actually buy this way

• Socks: Darn Tough. Unconditional lifetime, zero thought required after the first order.
• Outer layer: Patagonia, bought used or on sale and kept alive through their repair program.
• Anything with a true lifetime warranty: some bags, some tools, some boots. Read the actual policy first, confirm it is real, then buy once and forget it.

Fast fashion is a treadmill that bills you forever. Step off it. Buy a few good things one time, keep them for a decade, and put the money you were bleeding on replacements somewhere better.

More of the same thinking, applied to an entire expensive city, is in Frugal SF.

The prizes are real money

Hackathon prizes are not gift cards and pizza. Serious events pay thousands to the top teams, and crypto hackathons (ETHGlobal and the like) routinely put five and six figures of total bounties on the table. Even mid-size company and university hackathons hand out hundreds to low thousands per winning track. And, crucially, they stack.

The cheat code: stack the sponsor bounties

Most hackathons have a main prize plus a pile of sponsor bounties, smaller prizes for using a specific company’s API or hitting a particular theme. The winning strategy is not to build one ambitious thing chasing the grand prize. It is to build one focused project that qualifies for as many bounties as possible.

A single weekend project that meaningfully uses three sponsors’ tools can win three separate prizes at once. So read the entire bounty list before you write a line of code, then design your project to hit several bounties on purpose. That is where the money actually is, and most teams ignore it.

What actually wins

• A working demo beats a big idea. Judges see dozens of projects. The one that runs and demos cleanly in two minutes wins over the one with grand ambitions and nothing that works. Scope tiny, finish it.
• A tight two-minute pitch. Say the problem, show it working, name the sponsors you used. Done.
• Polish the one flow you demo. One flawless path through the app beats five half-built features.
• Target the bounties out loud. Free money is sitting in the sponsor list. Build toward it and say so.

Where to find them

• Devpost: the main listing site for hackathons, online and in person.
• Major League Hacking (MLH): student-focused but open, a huge calendar of events.
• ETHGlobal and crypto hackathons: the biggest prize pools going, if you can stomach web3.
• Company and university hackathons: check local tech companies and universities. In a hub like San Francisco, there is almost always one running.

The frugal-life angle

Even when you do not win, you come out ahead: free food the entire weekend, swag, sometimes travel or lodging covered, and a fresh project for your portfolio. When you do win, it is real cash for two days of work you would half-enjoy anyway, and the skills you sharpen are the exact ones that make you more employable. Do a few a year, get a little better each time, and it turns into a genuine line of income that pays you to practice.

While everyone else is buying a $15 sad desk lunch, you can be getting paid to eat at a hackathon. That is about as frugal as income gets.

Speaking of free food, hackathons are just the catered end of the wider SF tech-event circuit. The rest of living well here for cheap is in Frugal SF.

The guarantee, briefly

The Ironclad Guarantee covers defects with a repair, replacement, or refund. The Worn Wear program repairs normal wear and tear on top of that. That is the official line. Now the part that actually matters.

What actually works

• Most repairs come back free. Send in a jacket with a busted zipper, a blown seam, or a small tear, and more often than not it comes back fixed at no charge. Even the repairs that are not free are cheap next to buying the thing again.
• US stores and the US repair center ship it back to you free. You mail it in or drop it at a US store, and the repaired item comes back with free return shipping. Your worst case is paying to send it one way, and if you drop it in-store you often pay nothing at all.
• Route everything through the US. This is the one people get wrong. Non-US stores and distributors frequently will not honor repairs or the warranty the same way, if at all. If you are outside the US, do not waste time arguing with a local shop that shrugs. Handle it through US operations: in-store when you visit, or mailed to the US repair center.
• Repair beats replace, and that is fine. They will keep your gear alive for years. Do not walk in expecting a brand-new item for something that is simply old. Expect it patched, re-zipped, re-stitched, and handed back good for another few seasons. That is the win.

What does not work

• Expecting a free brand-new replacement for normal wear. That is not the deal. The deal is that they keep it going. Ask for a repair, not an upgrade.
• Warranty service at non-US stores. Save yourself the headache and route it through the US.
• Obvious intentional damage. It is a repair guarantee, not a cheat code. Treat it like one and you ruin it for everyone.

The full-value strategy

1. Buy quality once, cheap. Shop Worn Wear (their own used-gear store) and sales. You do not need a wall of gear, you need one good piece that is actually guaranteed.
2. Wear it into the ground. That is the point of owning good gear.
3. Feed it into the US repair pipeline when it wears. Most fixes free, return shipping free.
4. Repeat for a decade. One shell, maintained this way, outlasts five disposable jackets and costs less than the pile of them would have.

That is the buy-it-for-life idea taken to its logical end. The socks version, Darn Tough, is even simpler, and the whole gear-frugality mindset is in buy it once. The rest of living well in an expensive city for cheap is in Frugal SF.

The cheap models are good now

The Chinese labs have caught up on the things that matter for daily use. Two worth knowing:

• GLM 5.2 (from Zhipu). Strong general and coding model, available through a subscription that costs a fraction of the American plans. Their coding plan in particular is famously cheap for how much you get.
• Qwen 3.7 Max (from Alibaba). A capable frontier-class model you can use free in the browser, and the Qwen family also ships open weights, which means you can run smaller versions on your own machine and pay nothing at all.

For writing, summarizing, coding help, data cleanup, translation, and general question answering, these are more than good enough. You will not notice the difference on ninety percent of your tasks, except on the bill.

Default cheap, escalate rarely

The strategy is simple. Make a cheap or free model your default for everything. When you hit a task that truly needs the strongest reasoning available, a genuinely hard problem, a subtle piece of code, something where the best model earns its keep, then pay for one month of the premium tool, do the work, and cancel. You are paying for the frontier only in the rare moments you actually stand at the frontier.

Most people do the opposite. They pay for the most expensive tool every month and use it to rewrite a paragraph. That is the AI version of buying a truck to carry groceries.

Run it yourself for free

The cheapest tier of all is your own hardware. Qwen and other open-weight models run locally, no subscription, no data leaving your machine. I built a whole offline AI chat app around exactly this, a private model on my own device that costs nothing per message and works on a plane. For a lot of daily use, a local model is all you need, and the running cost is zero forever after the download.

The honest tradeoff

I am not going to pretend the gap is zero. For the hardest reasoning and the most demanding coding, the top American models still hold a real edge, and if your living depends on that edge, pay for it, it is worth every dollar. But be honest about how often you are truly at that edge. For most people it is a few times a month, not every day. Match the tool to the task and the savings are automatic.

The move

• Pick a cheap or free model, GLM or Qwen, and make it your everyday default.
• Cancel the premium subscription you are paying out of habit.
• Keep the option to pay for one month of a top model when a hard task genuinely needs it, then cancel again.
• For private or offline work, run an open-weight model locally and pay nothing.

Five hundred dollars a year for tools you use to reformat lists is not frugal. Default to the cheap model, keep the premium one on standby, and spend the difference on something that matters. More of the same thinking, applied to an entire expensive city, is in Frugal SF.

Hosting the front end: Vercel, Cloudflare, Netlify

For websites and web apps, three platforms host you for free:

• Cloudflare Pages is my default. Static sites and front ends deploy free, with a global CDN, free SSL, and no bandwidth bill worth worrying about. Cloudflare also gives you free DNS and can put your whole site behind its network for nothing.
• Vercel has a free hobby tier that is excellent for Next.js and other frameworks, with automatic deploys straight from your Git repo.
• Netlify and GitHub Pages round it out. GitHub Pages in particular hosts any static site free, straight from a repository.

Between these, hosting a personal site or a small app is simply a solved, free problem.

The database: MongoDB Atlas, Supabase, Neon

The part people assume they have to pay for, a real database, is also free at the sizes most projects need:

• MongoDB Atlas has a free forever M0 cluster. It is small, but it is a genuine cloud database that is plenty for a side project or an early product.
• Supabase gives you a free Postgres database with authentication, storage, and APIs on top. For a lot of apps this is the entire backend, free.
• Neon offers a serverless Postgres free tier that scales to zero when nothing is using it, so you pay nothing while it sits idle.

The rest of the plumbing, also free

• Cloudflare Workers and R2 run serverless functions and object storage with free tiers, and R2 famously does not charge for egress, which is where storage bills usually explode.
• Auth comes free with Supabase, or from other providers with free tiers.
• Email, analytics, error tracking, almost all of it has a free tier big enough for a project that is not yet making money.

The one thing worth paying for: the domain

The single cost I do pay is a domain name, and even that is cheap. A .com from Porkbun or Cloudflare runs about ten to fifteen dollars a year. That is the whole hosting budget for a real, live product: roughly a dollar a month for the name, and free for everything else.

Watch the catch

Free tiers change, so two rules. First, read the current limits before you commit, since platforms occasionally cut or remove a free plan, and you do not want your database on the one that just did. Second, free tiers throttle or sleep under load, which is fine for a project with light traffic and something to fix later if you ever get real scale. That is a good problem, and by the time you have it, the app is earning enough to pay its own bills.

The move

• Front end on Cloudflare Pages or Vercel, deployed from Git.
• Database on MongoDB Atlas, Supabase, or Neon, whichever fits your stack.
• Serverless bits and storage on Cloudflare Workers and R2.
• Buy one cheap domain and point it at the free host.

This is exactly how I shipped the apps I have built without a hosting bill. The barrier to putting something real on the internet is not money anymore, it is just doing it. More of the build-it-for-cheap mindset is over in Frugal SF.

The bag fee is the actual price

Budget airlines make their money on fees, not fares. The cheap ticket is bait. On Frontier or Spirit, a carry-on or a checked bag can run $30 to $60 or more each way, often more than the seat itself. So the entire game of flying budget cheaply is one thing: do not pay the bag fee.

The core move: personal item only

The one bag that is always free is the personal item, the one that fits under the seat in front of you.

• Learn the exact sizer dimensions for your airline and buy a bag that maxes them out. A backpack built right up to the limit swallows a shocking amount of stuff.
• Pack light and pack smart. Roll your clothes, use compression or packing cubes, and be honest about what you actually need for a few days.
• For most short trips, a maxed-out personal item is genuinely all you need. No carry-on, no checked bag, no fee.

Wear your luggage (yes, really)

Here is the loophole the video takes to its logical extreme: anything you wear is not a bag. So wear your heaviest stuff instead of packing it.

• Put on your bulkiest jacket, your boots, and a couple of layers before you board.
• Jackets with big pockets are free carry-on. Stuff them with the heavy little things: chargers, battery packs, socks, whatever.
• Cargo pants exist for a reason.

In the video I take this all the way and pile on something like twenty layers to get on a Frontier flight. It is a bit, obviously. But the principle underneath the joke is completely real: a worn jacket is free luggage, and budget airlines do not weigh you.

Never pay at the gate

If you truly need a bag, the price is not fixed, it climbs the closer you get to the plane.

• Buy it online during booking. That is the cheapest a bag will ever be.
• The airport counter is more. The gate is the most. Showing up with a bag you have not paid for is how you get hit with the top-tier fee.
• Never, ever wing it at the gate on a budget airline. That is exactly the mistake their pricing is designed to catch.

A few more tricks

• Bag bundles. If you know you will have bags, the “bundle” or “the works” fare is sometimes cheaper than paying for each fee separately. Do the math.
• Airline credit cards sometimes include a free checked bag. Worth it only if the free bag beats the annual fee for how much you actually fly.
• Weigh your bag at home so an overweight surprise does not undo all your savings.

The math

A $39 fare plus a $50 bag each way is a $139 trip. The same fare with a personal item only is $39. Pull that off a few times a year and it is real money, which is the whole point. On a budget airline the fare is never the price. The fees are. Beat the bag fee and these airlines are actually cheap.

Getting to the airport for $2.05 instead of a $60 Uber is the natural next move. More of the same over in Frugal SF.
