System Overview
LaunchFast is a founding codebase for TypeScript web applications. It exists to minimize irreversible mistakes in the first 90 days of building a product.
What this is
A pre-configured Remix application with authentication, payments, email, and infrastructure already integrated. The decisions are made. The patterns are established. The correctness constraints are encoded.
What this is not
- A boilerplate with maximum flexibility
- A framework you extend with plugins
- A collection of components to pick from
- A starting point for multi-cloud architectures
Core assumptions
- Single product
- Single primary deployment target
- Low operational load
- Small team (1-5 engineers)
- No dedicated infrastructure team
When these assumptions no longer hold, the correct response is explicit migration, not gradual configuration.
Where to start
- Correctness Invariants — What guarantees this system provides
- Project Structure — How the codebase is organized
- What's Intentionally Missing — Features excluded by design
