LaunchFast
AI writes your code. Who checks the architecture?
LaunchFast ships with machine-readable guardrails that prevent AI tools from breaking your codebase.
AI tools are fast. That is the problem.
Cursor, Claude, Copilot — they write any code you ask for. Entire features in minutes. It feels like a superpower.
But they also silently introduce a second auth system, swap your database engine, or add a plugin architecture you never asked for. They optimize for the immediate request, not the long-term coherence of your codebase.
By the time you notice, you are 10,000 lines deep. The auth system has two competing patterns. The database layer assumes two different ORMs. The deployment config references infrastructure that was never set up.
The cost of fixing it exceeds the cost of starting over. And you only discover this after months of building on a broken foundation.
The faster you ship, the faster you lock in mistakes.
Why speed needs a constraint
- 01AI accelerates code production.
- 02Faster code compresses decision time.
- 03Compressed decision time increases errors in foundational choices.
- 04Foundational errors become irreversible quickly.
- 05Therefore: the constraint is not speed. It is correctness.
LaunchFast ships with AI guardrails — machine-readable 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. Not just a template. A founding state that stays correct as you build.
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.
