01.Evaluation guide

Who it suits

A team that wants one API definition to produce both a docs site and client SDKs, with llms.txt, an MCP server and an AI assistant on the free plan, which covers 10 team members and 1,000 pages.

Consider something else if…

You need a paid plan between free and custom. Fern Docs lists a free plan and an Enterprise plan quoted by sales and nothing priced in between, and SSO and self-hosting are Enterprise-only.
