LaunchFast
The only boilerplate that makes AI safe to use.
Machine-readable guardrails that prevent AI tools from breaking your architecture. No other boilerplate does this.
Every boilerplate gives a starting point. None protect it.
Every boilerplate gives you a starting point. None of them protect that starting point from AI tools.
You paste your codebase into Claude or Cursor, ask for a feature, and the AI silently rewrites your auth layer, adds a second ORM, or restructures your deployment config. The code compiles. The architecture is broken.
This is not a bug in AI tools. It is a missing constraint. AI optimizes for the immediate request — build this feature, fix this error — without maintaining awareness of your architectural boundaries. It does not know that you have one auth system, one database pattern, one deployment target.
The result is architectural drift. Slow, silent, cumulative. Each AI-generated change is locally correct and globally destructive. By the time you notice, the codebase has two competing patterns for everything.
No amount of careful prompting fixes this. The constraint has to be machine-readable.
Why guardrails must be machine-readable
- 01AI tools are powerful but unsupervised.
- 02They optimize for the immediate request, not architectural coherence.
- 03No boilerplate constrains AI behavior after setup.
- 04Architectural drift is silent and cumulative.
- 05Therefore: the constraint must be embedded in the codebase and readable by AI.
LaunchFast includes machine-readable guardrails — constraints that AI tools read before writing code. They prevent architectural drift, enforce boundaries, and keep your codebase correct even when AI is writing most of it. No other boilerplate does this.
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.
