Overview

Scalar is an open-source API platform founded in 2023, operating under the MIT license and self-describing as 'The OpenAPI Company.' Built around the OpenAPI standard, Scalar provides a suite of developer tools covering the full API lifecycle: interactive API reference documentation rendered from OpenAPI/Swagger specifications, an offline-first REST API client, a centralized API registry with Git integration, hosted developer docs with Markdown and MDX support, automated SDK generation, and an MCP-compatible AI agent interface. The platform has gained significant traction — exceeding 1 million developers, 50,000 APIs, and 10 million open-source installs — and is notably the default API documentation UI for Microsoft's .NET 9+ Web API projects, replacing Swagger UI. Scalar targets API-first companies, platform engineering teams, and independent developers.
