Mintlify vs Stoplight
Side-by-side comparison of features, pricing, ratings, and alternatives.
Mintlify is a documentation platform that helps teams build and maintain product and API documentation that stays current automatically. It positions itself as a knowledge layer for both human readers and AI agents, offering an API playground, authentication-aware docs, and an MCP server so AI tools can query documentation directly. The platform is used by companies ranging from large enterprises like Microsoft and Anthropic to YC-backed startups, and reports serving tens of millions of documentation page views. Paid tiers add unlimited editor seats, automation features, preview deployments, and enterprise controls like SSO, SCIM, and RBAC.
Stoplight, now part of SmartBear, is an API design and documentation platform built around the OpenAPI specification. It gives teams a visual editor for designing APIs, generates interactive documentation automatically, and spins up local mock servers so front-end and back-end teams can work in parallel before an API is fully built. Stoplight promotes a design-first workflow with reusable models and components to keep specs DRY, and gives organizations visibility across their whole API portfolio. It also maintains open-source tooling, including the Spectral linter, the Prism mock server, and the Elements documentation component, and counts companies like Calendly, Schneider Electric, and PagerDuty among its customers.

- Pro plan jumps to a high fixed monthly price
- Enterprise pricing is not public
- AI-agent focus may be more than teams need for simple docs
- Higher tiers (Pro Team, Enterprise) get expensive for larger teams
- Full governance and SSO features are locked behind the top pricing tiers
- Interface is centered on OpenAPI, so it's less suited to non-REST API styles
