Playground

Paste an OpenAPI document — or fetch one by URL — and see the exact Rust the generator emits. The real generator runs in your browser as WebAssembly; nothing is uploaded.

OpenAPI document (YAML or JSON)

Generated files appear here.

Pick an example on the left to see typed models, an async client, and the dependency fragment the generator produces.

Runs openapi-to-rust compiled to WebAssembly. Same pipeline as the CLI, minus writing files. The downloaded archive is a complete crate — extract it and run cargo build. Constraint metadata is emitted as doc comments — generated code carries no runtime validation dependencies.
