Overview

Scalar is an API platform founded in 2023 by Marc Laventure and Cameron Rohani, headquartered in San Francisco and run by a small team of around ten people. It is built around the open-source Scalar project, a popular renderer for OpenAPI and Swagger specifications that also ships a standalone interactive REST API client.

The commercial Scalar platform layers hosted documentation, an API registry, SDK generation, and developer portal tooling on top of that open-source foundation, letting teams turn an OpenAPI specification into a full branded developer portal with a live, interactive request runner.

Key Features

Scalar parses OpenAPI/Swagger specs and renders interactive documentation with a built-in request runner that lets developers test API calls directly from the docs. Its open-source REST client supports collections, environments, and pre/post-request scripting.

Paid plans add custom domains, Git sync for docs-as-code workflows, Markdown/MDX authoring, generated SDKs in multiple languages, hosted MCP servers for AI agent integration, API versioning, and full developer portal features like landing pages and guides.

Pricing

The Free plan includes hosted docs, the API client, one editor seat, unlimited viewers, and 50 monthly AI credits, limited to three APIs in the registry. The Pro plan costs 72 dollars per month and adds custom domains, Git sync, SDK generation, hosted MCP servers, and 500 monthly AI credits.

Enterprise pricing is custom and adds SSO/SAML, RBAC, SLA-backed priority support, and migration services. Additional SDK languages on the Pro plan cost 100 dollars each per month.
