Alternatives to Slab
Polished hosted team wiki
Slab ranks #5 of 9 in Team wikis, with an Alt Score of 85. It is proprietary and freemium from $6.67/user/month (billed annually). 12 of 12 checklist rows are verified against a public source.
Teams and growing companies that need a shared home for internal documentation, from non-technical staff to engineers.
A clean, distraction-free editor for writing and organizing docs, with topics/collections to structure content and powerful search to surface answers quickly. Slab integrates with tools like Slack, Google Workspace, and GitHub so content stays connected to where teams already work, and supports collaborative editing with version history.
Team members write and organize documents into topics, then use search or browsing to find what they need; connected integrations let content be created or referenced directly from other tools.
