Scalar
Industry leading Developer Docs, SDKs, API Client & Registry for your APIs.

Scalar is a purpose-built API platform offering developer documentation, SDK generation, an API registry, and an open-source API client — all centered around the OpenAPI standard. It allows teams to upload and version OpenAPI documents, generate type-safe client libraries, and write or sync beautiful API documentation. The platform positions itself as a modern, open-source alternative to tools like Postman, with CI/CD integration and Git sync capabilities.
Users connect their OpenAPI documents to Scalar, which then generates documentation, type-safe SDKs, and provides an offline-first API client and centralized registry — all synced via Git integration.
