Overview
Scalar turns an OpenAPI or Swagger document into an interactive API reference, and includes an offline-first API client for sending requests. You can add the reference to most web frameworks or load it in a single HTML file from a CDN, with no build step.
What it does well
Scalar renders API references you can read and try out in the browser, with themes and configuration to match your brand. The API client works offline and is built around OpenAPI, so requests and documentation stay in sync. There are integrations for many frameworks, and an agent skill helps coding agents set it up in a project. Scalar's paid platform adds hosted docs, SDKs and MCP servers on top.
Why it’s in the collection
Scalar is a polished, open-source way to give an API good documentation and a client from the OpenAPI file a team already has. It's MIT-licensed.
