Ecosystem

Adapters, Plugins, Parsers & Middlewares

Everything you need to generate your entire API layer

Adapters

OpenAPI & Swagger support

Parse your API specification into the universal AST that every plugin understands.

Explore Adapters

Adapter OAS

Plugins

TypeScript clients, React Query hooks, Zod schemas, mocks and more

Official and community plugins that generate every layer of your API from a single OpenAPI spec.

Parsers

TypeScript and custom output formats

Parsers control how generated code is serialised — swap or extend them to match your code style.

Middlewares

Post-process and transform generated output

Middlewares hook into the build lifecycle to post-process generated output — add barrel files, transform code, or run custom side-effects.
