My whole company
runs on $21 a month.
A live product with paying customers running through Stripe. Twenty dollars goes to Claude, one dollar to the domain, and everything else rides a free tier built for this stage. Here's every tool and what it costs.

The short answer. You can build and run a real software company for about twenty one dollars a month. Twenty dollars pays for Claude, which writes the code. One dollar pays for the domain. Every other tool runs free at launch scale: hosting, database, auth, payments, email, caching, analytics, and error tracking. Stripe is the only other cost and it takes a small cut of sales, so it only bills you after a customer has paid.
Every tool, every price.
Thirteen tools. One earns a subscription, one costs a dollar, the rest are free at this stage. Nothing hidden.
Verified July 25, 2026. Prices are monthly, at launch and early growth scale.
What people think they need
$2,000
Paid team seats, a managed database, a paid auth provider, an email platform, an analytics suite, and a pile of tools bought to feel legitimate. It looks like a company.
What it actually takes
$21
The same product, shipped. Users can't see your stack. They see what you built and whether it works. The gap between these two numbers is pure story you're telling yourself.
How the pieces connect.
A shopping list is useless without the wiring. Here's the path a single feature takes, from an idea to a paying customer, across all thirteen tools.
Claude writes it
I describe the feature in plain English and Claude writes the code. It's the one tool on this list that earns a subscription, because it's doing the work a developer would.
GitHub stores it
Every change is committed to a private GitHub repo. Free, and it's the trigger for everything downstream.
Vercel deploys it
A push to GitHub auto deploys to Vercel. You never touch a server, and the free hobby tier holds up under real traffic.
Namecheap and Cloudflare front it
A one dollar a month domain from Namecheap, pointed through Cloudflare for free DNS and a CDN. The app is now live on a real address.
Clerk logs users in
Sign up, sign in, and sessions come from Clerk. Its free tier covers thousands of users before it costs a cent.
Supabase holds the data
A managed Postgres database on Supabase stores everything. Free tier is a real database, not a toy.
Stripe takes the money
Stripe handles checkout and subscriptions. No monthly fee. It only takes a cut after a customer pays, which is the fairest pricing in software.
Resend emails them
Receipts, resets, and notifications go out through Resend. Free up to a few thousand emails a month.
Upstash caches it, Pinecone searches it
Upstash caches hot data and runs queues. Pinecone does the AI search. Both free at this scale.
PostHog and Sentry watch it
PostHog shows me what users actually do. Sentry pings me the moment something breaks. Both free, both running in production.
The whole stack, live.
Every one of these is a product you can open right now, not a logo on a slide. These are screenshots of their homepages, pulled live.
The honest part
Where it costs more.
- Stripe is never free, it takes about 2.9% plus a fixed fee per charge. But it only costs you once a customer has already paid you, so it comes out of revenue, not your pocket.
- The free tiers hold until you get real scale: heavy traffic, large storage, or high email volume. When you cross those lines you start paying, but by then you have the users and revenue to justify it. That's a good problem.
- This is the launch and early growth stack. A fifty person team would outgrow it, and that's the point: it gets a real product live before you've spent much finding out whether anyone wants it.
The quick questions.
Is this really enough to run a real company?
Yes. This exact stack runs a live product with paying customers through Stripe. Users never see your stack, they see what you shipped. The tools here ship the same product a two thousand dollar stack would.
How much does it actually cost per month?
Twenty one dollars. Twenty for Claude, one for the domain. Every other tool runs on a free tier at this stage. Stripe takes a percentage of sales but has no monthly fee.
When do you start paying more?
When you outgrow the free tiers: high traffic, large database storage, or thousands of emails a day. Each tool has generous limits built for exactly this early stage, so you only pay once you have the users to justify it.
Do you need to know how to code?
You need to be able to describe what you want clearly. Claude writes the actual code. You still have to understand what you're shipping, but you're not writing every line by hand.
Are free tiers a trap that will rug you later?
No. Every tool here has a paid path you graduate onto when you scale, and your bill only grows because your product did. You're never stuck, and nothing here holds your data hostage.
Free, no catch
A new one, almost every day.
