The short version
- Each has a real cost: MkDocs no built-in versioning, which Docusaurus provides and documentation teams eventually need; 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: MkDocs covers Plain Markdown, 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.
MkDocs
- No built-in versioning, which Docusaurus provides and documentation teams eventually need
- Extending past the theme means writing Python plugins
- Markdown only, so embedding interactive components is not the model
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
MkDocs: Is MkDocs free?
Yes, open source under the BSD licence. The Material theme has a free version and a paid Insiders edition.
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.
MkDocs: MkDocs or Docusaurus?
MkDocs is simpler and faster to adopt, especially for Python teams. Docusaurus offers versioning, internationalisation and React components, which matter once documentation grows.
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.
MkDocs: Does MkDocs support versioned docs?
Not natively. Plugins such as mike add it, where Docusaurus includes versioning in core.
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.
