Scalar review

Scalar earns its place because one OpenAPI document drives hosted reference docs, an API client, an SDK and hosted MCP servers. Pro costs $125 a month billed yearly or $150 monthly and includes 5 editor seats, up to 15 APIs, one SDK up to 100 endpoints, custom domains, Git Sync, Markdown and MDX pages, access groups, a full developer portal and 500 Agent Scalar credits. Business at $500 a month billed yearly raises the limits to 25 APIs and 10 editor seats and adds SSO and subpath hosting. Every plan includes one SDK, and extra SDKs cost $150 a month each up to 100 endpoints. The Free plan lists hosted OpenAPI docs and landing pages for up to 3 APIs with 1 editor seat, but Scalar states that after the 7-day trial, publishing a Docs site needs a paid plan. For DevRel teams that also ship client libraries, the combined price is low next to buying docs and SDK tools separately.
