Scalar is a modern API platform that provides developer-first tools for API documentation, SDK generation, API clients, and registry services. It enables teams to create beautiful, up-to-date documentation using Markdown, MDX, OpenAPI, and AsyncAPI, with two-way Git synchronization.
The platform offers type-safe SDK generation for multiple languages including TypeScript, Python, Golang, PHP, Java, and Ruby, all from a single OpenAPI document. Scalar also provides a fully open-source, offline-first API client that supports collaboration and avoids vendor lock-in.
Scalar emphasizes open-source values, OpenAPI compliance, and seamless CI/CD integration. Its ecosystem supports API design, documentation, testing, and governance, making it easier for developers to adopt and integrate APIs efficiently.
