Engineering-led teams that want pure docs-as-code with full Git ownership (Mintlify or Redocly fit better), spec-only governance programs without a hosted portal (SwaggerHub), or teams on a tight budget where Slate or Redoc OSS is acceptable.
Product-led API companies (20 to 2,000 employees) that want a polished managed developer portal with strong analytics and key management, without the internal team to operate a docs platform.
Why we say this
Editorial pulled these weaknesses from ReadMe’s product card in our Top 10 API Documentation and Developer Portals Software for 2026:
- ! Enterprise pricing is opaque and steps up sharply at scale
- ! Custom theming flexibility behind Mintlify and Redocly Realm
- ! Migration off ReadMe is non-trivial (proprietary content model)
- ! AI assistant features arrived later than Mintlify and Theneo
- ! Some developer-experience surfaces (changelogs, recipes) still feel bolted-on
If ReadMe is wrong for you, consider these instead
Same API Documentation / Developer Portals category, different best-fit buyer.
Best for
Spec-first engineering teams and platform groups (50 to 5,000 employees) that already use Redoc OSS, want commercial governance and linting, and treat OpenAPI as the contractual source of truth.

Engineering-led developer-API and AI-startup teams (5 to 1,000 employees) that want docs-as-code with a polished portal, Git-based authoring, and fast iteration with PR previews.

API teams (10 to 5,000 developers) already standardized on Postman that want a documentation surface in the same workspace without buying a separate portal product.
