The short version
- Only GitBook has a free tier, so it costs nothing to try first.
- Each has a real cost: Redocly only as useful as your commitment to OpenAPI; teams without a maintained spec get little from it; GitBook hosted, so you do not own the rendering pipeline and are subject to platform changes
- They diverge on capability: Redocly covers OpenAPI reference docs, GitBook covers Two-way Git sync.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Redocly
- Only as useful as your commitment to OpenAPI; teams without a maintained spec get little from it
- The portal and governance features are paid, while the open-source renderer covers only reference rendering
- Linting rules are another thing to configure and argue about before value appears
- Narrower than a general documentation platform, by design
GitBook
- Hosted, so you do not own the rendering pipeline and are subject to platform changes
- Git sync is powerful but conflicts between browser and repository edits are confusing to resolve
- Pricing scales per user, which gets expensive where many people contribute occasionally
- Less customisable than a static site generator you control end to end

Answered from the vendors’ own pages
Redocly: Is Redocly free?
The Redoc renderer and CLI are open source and free. The developer portal and governance features are paid, with pricing published on the vendor site.
GitBook: Is GitBook free?
There is a free tier for public documentation, with paid team plans above it. Check current rates with the vendor.
Redocly: What does the linter do?
It enforces rules on the OpenAPI spec itself in CI — missing descriptions, naming, examples — so a poor spec fails the build rather than becoming poor documentation.
GitBook: How does Git sync work?
Changes made in the browser commit to the connected repository, and commits to the repository appear in GitBook, so both editing routes stay in step.
Redocly: Do I need OpenAPI to use it?
Effectively yes. Without a maintained specification there is little for it to work with.
GitBook: GitBook or Docusaurus?
GitBook is hosted and lets non-technical people write directly. Docusaurus is free and fully controllable but assumes contributors work in a repository.
