Scalar is an open-source API platform centered on rendering beautiful interactive API references from OpenAPI/Swagger documents, with a built-in API testing client. The monorepo also includes an offline-first API client, mock server, CLI, SDK generator, and framework integrations for 35+ frameworks.

Use cases

render interactive API documentation from an OpenAPI spec
test REST APIs with a modern Postman alternative
generate SDKs from an OpenAPI document
mock API responses from an OpenAPI file
embed API reference docs in Express, Fastify, FastAPI, or Next.js apps
upgrade legacy Swagger 2.0 documents to OpenAPI 3.1
publish a developer portal with Markdown and MDX docs

When to choose

you want modern, self-hostable API docs from an OpenAPI document instead of dated Swagger UI
you need an integrated docs + API client + SDK generation workflow driven by one spec
you use a popular framework and want drop-in API reference integration

When to avoid

you need GraphQL-first documentation rather than OpenAPI/REST
you require enterprise features like SSO/SAML or RBAC without a paid plan
you only need a simple static docs site with no API component
