Pros and cons
Notion
Pros
- Highly flexible structure (pages + databases) for many documentation styles
- Strong collaboration and sharing controls for internal/external docs
- Large template ecosystem and easy-to-build internal wikis
- Integrates well with common tools (Slack, Google Drive, GitHub, etc.) and supports embeds
Cons
- Can become messy without governance (naming conventions, database design, permissions)
- Performance can degrade with very large workspaces/databases
- Advanced knowledge-base needs (granular publishing workflows, strict IA, analytics) may require specialized tools
Slab
Pros
- Clean, intuitive writing and reading experience that drives adoption
- Strong search and organization for finding answers quickly
- Useful integrations that connect docs to day-to-day tools
- Good permissioning and sharing controls for growing teams
Cons
- Advanced admin/security features may require higher-tier plans
- Less flexible than fully custom documentation sites for complex public docs
- Pricing can add up as headcount grows compared with flat-fee wiki options
