Already built, tested and pen-tested. You only write the code that makes you money. Clone it tonight, charge your first customer this weekend.
You could absolutely build every piece yourself. Here's the time it honestly takes:
= 60+ hours of groundwork before your first feature
LaunchKit hands you those hours back ↓

bin/setup, the full test suite going green, a Stripe checkout - filmed end to end. No cuts, no magic.
3-minute walkthrough - click to play
Run bin/setup, point it at PostgreSQL, and the app boots - no Node, no Redis.
Drop your Stripe and Google keys into Rails credentials. One encrypted place.
Auth, billing, admin and onboarding are done. Ship your first feature today.
I've spent 10+ years writing Ruby and Rails, publishing about the language and shipping production apps for companies and for myself.
Every single project started the same way: rebuild auth, re-listen to Stripe webhooks, re-do the admin, re-write the onboarding. Weeks of plumbing before a single line of product code.
So I built LaunchKit for 3 reasons:
Every line is tested (812 specs), scanned (Brakeman, bundler-audit) and pen-tested (OWASP ZAP). It's the codebase I wish someone had handed me years ago.
Every claim on this page is verifiable in the codebase you download. Here's what the tooling says:
The full RSpec suite runs green - models, requests, system specs. You inherit the safety net.
A baseline penetration scan of the running app comes back clean. Headers, cookies, CSP - handled.
Brakeman static analysis, bundler-audit dependency scan and RuboCop all pass on every commit.

Founder's launch · only 9 of the first 100 seats left
“I shipped my MVP in a weekend instead of a month. Auth and billing just worked out of the box.”
“The code reads like a tutorial. Onboarding two engineers took an afternoon, not a sprint.”
“Finally a boilerplate I can actually maintain - tests, docs and conventions are all there.”
The same 60+ hours you saw above, itemized line by line:
= 60+ hours of plumbing, plus an extensible foundation you'd never find time to build — one payment of $129, yours forever.

Rails 8, Hotwire (Turbo + Stimulus), TailwindCSS, PostgreSQL and the solid_* adapters - no Node build step and no Redis.
Yes. It's a boilerplate you clone and make your own - there's no runtime dependency on us. Pay once, build unlimited projects.
812 RSpec examples run green, plus RuboCop, Brakeman and bundler-audit on every commit and in CI. The app is also pen-tested with OWASP ZAP (0 findings). You can re-run all of it yourself right after cloning.
Same promise - ship fast - different foundation. LaunchKit is Rails 8 + Hotwire: one language end to end, no Node build, no Redis, server-rendered by default. And unlike most boilerplates, the quality is measurable: 812 specs, 0 CVE, 0 pen-test findings, all verifiable in the code you download.
Those are great for landing pages, but a business needs billing you can trust, auth without edge-case holes, and an admin. LaunchKit gives you a battle-tested foundation - and it makes your AI editor better, not obsolete: a complete, conventional codebase is the best context Cursor or Claude Code can get. Ask for a feature and the AI follows the existing structure, naming and tests.
It's built for them. Conventional Rails structure, consistent naming, a full test suite to validate generated code, and code generators (feature, service, webhook handler, admin resource) that give your AI a template to imitate.
If you're comfortable with Rails, yes. Modules are independent: swap Kamal for Heroku, Google OAuth for any of the 10 wired providers, or drop what you don't need. PostgreSQL is the only hard assumption.
Once you've downloaded the source it's yours forever, so it can't be refunded. That's exactly why this page shows real, verifiable numbers instead of promises - clone it, run bin/setup and the test suite, and judge the code in your first hour.
Kamal (your own server, from ~$5/mo) or Heroku - both documented step by step in the in-app guides. No Redis and no Node means one less service to pay for and babysit. Stripe only charges when you make money.
Everything above is already built, tested and pen-tested. Pay once, download the full source, and ship your app this weekend.
