RivetC# in, OpenAPI 3.1 out

Your C# types and endpoints are the source of truth. Rivet emits a faithful OpenAPI 3.1 spec; the OpenAPI ecosystem generates the types, clients, and validators.

Get Started

CLI Reference

C# Types -> OpenAPI Schemas

Roslyn reads your compiled C# — records, enums, brands, generics, nullability, validation attributes — and maps it to component schemas with full fidelity.

ASP.NET -> OpenAPI Operations

Controllers, minimal APIs, and compiler-enforced [RivetContract] definitions become operations derived from the real transport shape.

One Spec, Any Consumer

TypeScript types via openapi-typescript, a typed client via openapi-fetch, Zod via openapi-zod-client, docs via any OpenAPI renderer.

Rivet is a meta-framework over OpenAPI: it owns the C# → spec mapping and delegates code generation to the OpenAPI ecosystem.
