Stop vibe coding. Start shipping quality code with contracts.
Website • SpecFact CLI • Docs • Contact
We build contract-first, no-escape development tools that prevent bugs before they're written — not after they reach production.
Traditional software development finds bugs at deployment time. We enforce behavioral contracts during development, giving you:
- ✅ Prevention over detection — Stop bugs before they're created
- ✅ No-escape quality gates — Automated enforcement you can't bypass
- ✅ Brownfield-first — Works with existing Python codebases
- ✅ Offline-capable — No cloud dependencies or accounts required
