OpenAPI in. Packages and Docs out. Zero touches.

Generating code is only half the battle. Automate your entire developer experience pipeline. Build, test, publish idiomatic clients directly to native registries, and deploy interactive HTML docs—without a single click.

100% Automated Generation

Commit an OpenAPI spec and watch our GitOps pipeline instantly synthesize perfectly typed client libraries across 13 major languages. No human intervention, no configuration drift, just code.

Direct to Registries

Don't just dump generated files into a repo. Our automated pipeline handles the complex lifecycle: version bumping, dependency resolution, packaging, and publishing directly to PyPI, npm, crates.io, Maven, and more.

The Ultimate API Docs Frontend

We don't just generate SDK code; we generate the perfect developer portal to match.

  • 🚀 Zero-Config Static HTML

    Your documentation is compiled into lightning-fast, static HTML, CSS, and JS. No databases, no servers—just drop it into an S3 bucket or GitHub Pages and it works instantly.

  • 💻 Real Code Snippets

    Because we generate the SDKs, we also generate perfectly accurate copy-paste code snippets for every endpoint in all 13 supported languages.

  • ⚡ Interactive API Explorer

    Allow your users to make live API calls directly from the browser. Test request payloads, view raw responses, and debug integrations without leaving your documentation.
