Where Slab wins
- Slab takes fifth place for pricing that is easy to read: a free plan for up to ten users, then a Startup tier at $6.67 and a Business tier at $12.50 per user a month billed annually.
- The vendor describes itself as a fully remote company and positions the product as a wiki and knowledge base for organizing and finding documents.
- For a team of ten that wants a proper home for its processes without paying, it is a sensible choice.
Where it falls short
- The pages we could read gave little product detail, so integrations, security controls and AI features were not confirmed here.
- The only address in the terms is a copyright-agent notice address, not a stated headquarters.
- The free plan ends at ten users, which is the point where most growing companies need to pay.
- Wrong for buyers who must confirm a headquarters address and security certifications before a pilot, and for companies above ten people who want to stay free.
