Offscale - SDKs & Interactive API Docs

OpenAPI in. Packages and Docs out. Zero-touch.

Code generation is only half the solution. Automate your entire developer experience pipeline. Build, test, and publish idiomatic clients directly to native registries, and deploy interactive HTML docs—fully autonomously.

Autonomous SDK Generation

Trigger our GitOps pipeline with an OpenAPI spec to instantly synthesize strongly-typed client libraries across 13 languages. Eliminate manual intervention and configuration drift.

Native Registry Publishing

Go beyond repository generation. Our pipeline fully automates the release lifecycle—handling semantic versioning, dependency resolution, packaging, and publishing directly to package registries like PyPI, npm, crates.io, and Maven.

Interactive API Documentation

Complement your generated SDKs with a comprehensive, interactive developer portal.

🚀 Static HTML Compilation

Compile your documentation into performant, static HTML, CSS, and JavaScript. Host seamlessly on Amazon S3, GitHub Pages, or any static file server without backend dependencies.
💻 SDK-Integrated Snippets

Ensure perfect accuracy. Our documentation engine automatically integrates precise, copy-ready code snippets for every endpoint across all 13 supported languages, derived directly from the generated SDKs.
⚡ Interactive API Explorer

Enable users to execute live API calls directly from the browser. Validate request payloads, inspect raw responses, and debug integrations seamlessly within the documentation.

Interactive Live Demo Live Now

Experience our WebAssembly (WASM) powered pipeline locally in your browser. Input an OpenAPI spec and instantly preview the generated SDK code—fully client-side, with zero backend dependency.
