About

Scalar is an API platform for hosted OpenAPI docs, an open-source API client, SDK generation, MCP servers and developer portals.

Scalar is an API interface platform that starts with API documentation and extends into SDKs, MCP servers and developer portals. It includes hosted OpenAPI docs, a built-in API client, an SDK generator and an API registry, with Git Sync, Markdown and MDX support, custom domains and access groups.

The open-source MIT-licensed API client is offline first and runs on web, macOS, Linux and Windows. It supports collections, environments, pre-request and after-response scripting and a collection runner. SDK generation covers TypeScript, Python, Java, Go, C# and PHP with an automated GitHub workflow. Higher plans add SSO and SAML, RBAC, priority support and SLAs.
