Confluence vs Slab

Confluence

• Teams that run Jira and want documentation linked to their issues
• Company wikis and intranets organized into spaces per team or project
• Small teams: the Free plan covers up to 10 users

Slab

• Teams of up to 10 that want a free internal wiki
• Companies that want one place to search docs and connected tools
• Non-profits and schools, which can get the Startup plan free

Confluence

• The Free plan stops at 10 users and 2 GB of storage and has no space or page permission settings.
• The pricing page's default prices ($5.42 Standard, $10.44 Premium) are per-user averages for a 300-user team; the first 100 users cost $6.70 or $13.20 each.
• Enforced SSO and SCIM need a separate Atlassian Guard Standard subscription on every plan except Enterprise, which is sold on annual contracts only.
• The self-managed Data Center edition reaches end of life on March 28, 2029, when its subscriptions expire and it becomes read-only.

Slab

• The Free plan stops at 10 users and has no private topics, no custom domain and no AI features.
• SAML-based SSO, SCIM, the API and webhooks need Business at $12.50 per user / month billed annually; audit logs are Enterprise only.
• Slab has no read-only accounts: billing counts every user who can log in, and guests are capped at 3 or 5 per user below Enterprise.
• The downloads page offers desktop apps for Mac and Windows and a Chrome extension, but lists no mobile apps.

Confluence

Pages and spaces

Pages hold project plans, meeting notes and policies, and are grouped into spaces with a page tree. Several people can edit at once, with inline and page comments and version history.

Whiteboards

Freeform canvases for brainstorming and diagrams, with built-in links to Jira. Free allows 3 active whiteboards per user, Standard 10, and Premium and Enterprise have no limit.

Databases

Structured collections that gather information from Jira and other apps and can be laid out as tables, cards or boards.

Rovo AI

Rovo Search, Chat and Agents come with paid plans and are metered in monthly credits: 25 per user on Standard, 70 on Premium and 150 on Enterprise.

Automation

Rule-based automation with templates and a low-code builder. Monthly allowances run from 50 steps per subscription on Free to 500 steps per user on Enterprise.

Permissions and external sharing

Paid plans add space and page permissions, view-only public links, anonymous access and up to 5 free guests per paid user, each limited to a single space.

Slab

Posts and Topics

Content is written as posts and grouped into Topics, which organize related posts and give readers context. Posts and topics are unlimited on every plan.

Real-time editor and templates

The editor applies consistent formatting by default and lets several people work on a post at once. Templates are included on every plan.

Unified Search

One search box returns results from Slab content and from the tools connected to it, so answers stored elsewhere surface in the same list.

Post verification

A published post can be given a verifier and a review interval. A banner shows who verified it and when that expires, and verifiers are reminded to recheck it.

AI Autofix, Predict and Ask

Slab lists three AI capabilities: AI Autofix from the Startup plan, and AI Predict and AI Ask from Business. The Free plan includes none of them.

Integrations, API and webhooks

Standard integrations such as Slack, GitHub and Google Workspace are capped at 10 on Free. The GraphQL API, webhooks and premium integrations start on Business.
