LaunchFast
I spent 3 years making every mistake. Here's the codebase I wish I had.
Every choice in LaunchFast is informed by a real mistake already made. So you do not have to make them.
Foundational mistakes are inevitable — unless someone already made them
I rewrote my auth system three times. Migrated databases twice. Switched payment providers after discovering mine did not support my customers' countries. Each mistake cost weeks.
Not because the code was hard to write. Because the old code was woven into everything else. The auth rewrite broke session management. The database migration required rewriting every query. The payment switch meant rebuilding the entire subscription flow.
Every founder makes these mistakes. The question is whether you make them yourself or learn from someone who already did. The information exists — scattered across blog posts, Twitter threads, Stack Overflow answers. But knowing the answer is not the same as having a working implementation.
You can read about the right way to handle auth, payments, and deployment. Or you can start with a codebase where every decision was made by someone who already made the wrong one first.
Three years of mistakes, compressed into one correct starting point.
Why experience compounds into correctness
- 01Foundational mistakes are inevitable for every new project.
- 02Each mistake costs weeks of rework, not hours.
- 03The cost compounds as the codebase grows — each fix breaks dependent code.
- 04The only way to skip these mistakes is to start with decisions informed by them.
- 05Therefore: the constraint is not knowledge. It is starting from tested decisions.
LaunchFast is the codebase built from 3 years of real founding mistakes. Auth that works across providers. A database that does not need migrating at 10,000 users. Payments that handle real-world edge cases. Every choice informed by a mistake already made so you do not have to.
Inspect before buying
The documentation is public. The source code is open-source. Inspect both before spending a cent. If you disagree with the approach, you have saved yourself €199.
What you receive
The template (free and open-source)
- A TypeScript Remix codebase with authentication, payments, and email — integrated and tested
- SQLite deployment — starts single-region, scales globally with Primary-Replica when you need it
- Documentation that explains every decision, including what was deliberately left out
The CLI (what €199 buys)
- Correct initialization — the template is inert until the CLI sets it up as a working founding state
- AI guardrails that constrain AI assistants to preserve your architecture — not just at setup, but on every change
The code is free. Correct initialization and ongoing architectural protection is what you are paying for.
€199
One-time payment
The alternative is weeks of research and architectural decisions that may still be wrong. The cost when they are wrong: a rewrite.
€199
One-time payment. No subscription.
After purchase, you can authenticate with the LaunchFast CLI — it sets up the open-source template correctly and installs the AI guardrails that keep your codebase correct as you build.
