New Approach to REST APIs

The feTS Client and Server can be seamlessly used together for a comprehensive, type-safe API experience. Alternatively, they can function independently, providing you with the flexibility to adapt to your project's specific needs.

Harness the Power of OpenAPI

feTS leverages the OpenAPI specification for universal tool compatibility. Plus, enjoy the convenience of an out-of-the-box Swagger UI with our server.

JSON Schema Route Description

feTS utilizes the JSON Schema specification for route description, enabling integration with any tool within the JSON Schema ecosystem.

No Code Generation needed

Experience full type-safety with the feTS Client. It infers types from the OpenAPI spec and JSON Schema, eliminating the need for code generation.

Deploy Anywhere

feTS Server provides a super fast HTTP server that can run anywhere with the power of @whatwg-node/server
