The short version
- Each has a real cost: GitBook hosted, so you do not own the rendering pipeline and are subject to platform changes; Slab it is built for internal knowledge, so public product documentation on a custom domain with versioning is outside what the product does.
- They diverge on capability: GitBook covers Two-way Git sync, Slab covers Topics instead of folders.
- Prices and features above were last checked on 31 August 2026.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
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
Slab
- It is built for internal knowledge, so public product documentation on a custom domain with versioning is outside what the product does.
- There is no docs-as-code workflow, no git synchronisation and no markdown files on disk, so engineering-owned technical documentation ends up somewhere else anyway.
- Hierarchy is shallow by design, and organisations that genuinely need deep nested structure find topics an awkward substitute rather than an improvement.
- There is no offline mode, so a knowledge base that includes incident runbooks is unavailable during exactly the incident where the network is the problem.
- Pricing is per user per month, so organisations where most staff only read a handbook twice a year still pay a seat for each of them.

Answered from the vendors’ own pages
GitBook: Is GitBook free?
There is a free tier for public documentation, with paid team plans above it. Check current rates with the vendor.
Slab: Can I publish documentation publicly with Slab?
Posts can be shared by link, but it is not a product documentation platform. There is no custom domain publishing, versioning or API reference tooling.
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.
Slab: What does the free plan actually cover?
Up to ten users with unlimited posts and core integrations. It is a real free tier rather than a trial, and it is enough for a small company handbook.
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.
Slab: How does it compare with a general workspace tool?
Slab does less on purpose. There are no databases, boards or task views, which makes it faster to write in and much harder to turn into an unmaintained sprawl.
Slab: Does search really cover other tools?
Yes, connected sources are indexed and appear in results. That integration is the main reason to choose it, so verify your specific tools are supported before committing.
