Compiler for AI-coded systems
Define contracts once. Generate consistent code across API, DB, UI, and events. Regenerate safely anytime. No lock-in.
One contract, all surfaces in sync
Stop chasing drift between your API, database, UI, and events. One spec generates all outputs, guaranteed to stay consistent.
REST & GraphQL API
Type-safe endpoints with validation. Standard Express, Hono, Elysia, or Apollo handlers.
Database Schema
Prisma migrations and types generated from the same spec. Always in sync with your API.
UI Components
React forms and views derived from specs. Validation and types flow through automatically.
MCP Tools & Events
AI agent tool definitions and event schemas. Same contract, different surfaces.
Regenerate anytime without fear
Contracts enforce invariants. Breaking changes are caught at compile time, not production. Regenerate with confidence.
Spec-First Safety
AI agents read specs, not implementations. Generated code that violates contracts gets flagged automatically.
- Type-safe from spec to runtime
- Invariants enforced at compile time
- Breaking changes detected early
Version Control Built-in
Every spec change is tracked. Roll back to any previous version. Migrations are explicit and reversible.
- Git-native spec history
- Explicit migration paths
- One-click rollback
AI governance that actually works
Constrain what AI agents can change. Enforce contracts they must respect. No more hallucinated refactors breaking your system.
How contract enforcement works
Contracts define what the system should do. AI-generated code that violates these contracts is automatically flagged and rejected before it can cause damage.
Define
Write specs in TypeScript. Define inputs, outputs, and invariants.
Generate
ContractSpec generates code across all surfaces from your specs.
Enforce
Any code that violates specs is flagged. AI agents can't break contracts.
You own everything. Eject anytime.
ContractSpec is a compiler, not a prison. The generated code is yours — standard TypeScript, standard SQL, standard GraphQL.
Standard Tech Output
- TypeScript you can read and modify
- Prisma migrations you can run manually
- GraphQL schemas you can serve anywhere
- React components with no magic
- REST handlers that work with any framework
No Proprietary Dependencies
- No runtime library required
- No vendor-specific abstractions
- Works with your existing CI/CD
- Eject anytime, keep everything
- Open spec format
Like TypeScript compiles to JavaScript, ContractSpec compiles to standard code.
We're the compiler, not the prison.
Start small. Expand gradually.
You don't rewrite your app. You stabilize one module at a time. Start with one endpoint, prove value, then expand.
Pick one API endpoint. Write a spec. See what gets generated.
Add a few more specs. Compare generated code to existing code.
Migrate a full module. Enjoy multi-surface consistency.
