While Mintlify may look like a Markdown hosting service from the outside, the build versus buy question for documentation infrastructure goes much deeper than rendering Markdown. Beneath the surface, a complete platform requires self-updating content, search optimization, multiple editing interfaces, user feedback tracking, AI assistants, custom components, security features, MCP server integration, analytics, and SEO capabilities. Building these features in-house demands months of engineering resources that could instead be directed toward core product work.
