Confluence vs Slab: should you switch in 2026?

Last updated May 2026

If you're reading this, you're probably unhappy with Confluence. The search doesn't work. The interface feels like 2010. Pages take too long to load. Nobody maintains the wiki. You've heard Slab is the cleaner, faster, simpler alternative. You're wondering if migration is worth it.

Short answer: Slab fixes the design problem. It doesn't fix the maintenance problem. If your team stopped maintaining Confluence because it was ugly and slow, Slab might restart that habit. If your team stopped maintaining Confluence because nobody wants to maintain a wiki, Slab is a nicer wiki that nobody will maintain.

Side-by-side comparison

Where Slab wins over Confluence

The editor. This is the most immediate difference. Slab's editor is fast, clean, and modern. Writing feels pleasant. Confluence's editor has improved over the years but still feels a generation behind. If your team avoids contributing to Confluence because the writing experience is painful, Slab removes that friction.

Search. Slab's search works. Fast full-text search across posts and integrated apps (Slack, Google Drive, GitHub). Users praise it consistently. Confluence's search is its most documented weakness across every review platform. For finding content within the wiki, Slab is meaningfully better.

Simplicity. Topics instead of deeply nested page trees. Multiple topics per post instead of rigid single-parent hierarchies. Flatter structure that's easier to navigate and harder to lose things in. Confluence's space-and-page-tree model can become labyrinthine at scale. Slab stays clean.

Adoption speed. A new team member can use Slab productively within minutes. Confluence requires orientation: which space, which page tree, which templates, which macros. Slab's learning curve is near zero.

Price. Slab Startup at $6.67/user/month versus Confluence Standard at ~$5.42/user/month. Close on base price, but Confluence's Marketplace apps, Atlassian Guard for SSO, and storage expansion add costs that Slab doesn't have.

Migration. Slab has a Confluence importer. For most teams, migration is straightforward. Content transfers. Structure adapts. It's not painless, but it's not a six-month project either.

Where Confluence wins over Slab

Jira integration. If your team runs on Jira, this is the conversation-ender. Confluence pages link to Jira issues natively. Jira macros embed in Confluence pages. Sprint planning, incident reports, product specs, post-mortems, all flow between the two products. Slab has no Jira integration. For engineering teams in the Atlassian ecosystem, leaving Confluence means losing this integration.

AI. Confluence has Rovo AI on Standard+ with search, chat, and agents (25 credits/user/month). Slab has no AI. In 2026, a wiki with no AI capabilities is a hard sell for teams that expect AI-powered search and Q&A.

Marketplace. Thousands of apps for diagramming (draw.io, Gliffy), reporting, compliance, workflow automation, and more. Slab has no marketplace and limited extensibility. If your Confluence usage depends on marketplace apps, Slab doesn't have equivalents.

Enterprise compliance. SOC 2, HIPAA (with Atlassian Guard), data residency options. Slab has no SOC 2 certification. For regulated industries, Confluence meets requirements Slab doesn't.

Permissions depth. Space-level, page-level, and group-level permissions. Complex but powerful. For large organisations with granular access control requirements, Confluence offers more. Slab's permissions are simpler, which is fine for smaller teams but insufficient for enterprise governance.

Ecosystem maturity. 20 years. 250,000+ organisations. Massive template library. Extensive documentation. Large community. Enterprise support. Slab is younger, smaller, and less battle-tested at scale.

Native mobile apps. Confluence has iOS and Android apps. Slab is web-only with responsive design but no native mobile experience.

The question neither answers

Both are wikis. Both require your team to write documentation, maintain the structure, and keep content current. Slab makes this work more pleasant than Confluence. It doesn't eliminate the work.

If your Confluence decayed because the editor was painful and search was broken, Slab might fix that. A better tool can restart the documentation habit.

If your Confluence decayed because nobody on the team prioritises documentation maintenance regardless of the tool, Slab will decay too. It'll just look nicer while it does.

The underlying question: does your team want a better wiki, or does your team want knowledge to work without a wiki?

If you're already considering migration

Migrating from Confluence to Slab solves the design problem. You get a cleaner editor, faster search, simpler structure. The migration is manageable. Many teams have done it successfully.

But if you're already going through the effort of migrating away from Confluence, consider whether you should migrate to another wiki at all.

Fabric isn't a wiki. It's a knowledge system that organises itself. You save content, any file type, from any source, and the AI handles the rest. Semantic search finds things by meaning. No page trees to build. No topics to maintain. No documentation discipline required.

The AI understands every file type: PDFs to the paragraph, audio and video to the timestamp, images by visual similarity. Notes with real-time co-editing. A spatial canvas with live embeds. Annotations on any content. Bot-free meeting transcription. Tasks with due dates. Publishing with analytics.

No per-user pricing. Generous free plan. $5/month Plus.

If you're migrating from Confluence because the wiki doesn't work, Slab gives you a better wiki. Fabric gives you something that isn't a wiki at all. Both are improvements. The question is which problem you're solving.

How to choose

Switch to Slab if your team likes writing documentation but hates writing it in Confluence. You want a better editor, better search, and simpler structure. You don't depend on Jira integration. You don't need AI, marketplace apps, or enterprise compliance. Your team is small enough that Slab's simpler permissions work. You want the fastest path to a wiki that doesn't make people miserable.

Stay on Confluence if your engineering team runs on Jira. You need marketplace apps. You need enterprise compliance (SOC 2, HIPAA). You have admins who manage the wiki. You're too embedded in the Atlassian ecosystem for the migration to make sense.

Try Fabric if the problem isn't that you have the wrong wiki. It's that wikis don't work for your team. You want knowledge to organise itself. You want search by meaning across all content types. You want AI included at every tier. You want a team wiki that doesn't need a librarian. Generous free plan.

FAQs

Is migrating from Confluence to Slab hard?

Slab has a Confluence importer. For most teams, migration is straightforward. Complex page hierarchies and marketplace app content may not transfer cleanly. Budget 1-2 weeks for a mid-size Confluence instance.

Does Slab have AI?

No. As of 2026, Slab has no AI features. Confluence has Rovo AI on Standard+ with credit limits. Fabric has a full AI assistant included at every tier.

Does Slab integrate with Jira?

No. If your team depends on deep Jira integration, Slab is not a replacement for Confluence. This is typically the deciding factor for engineering teams.

Which has better search?

Slab. Its fast full-text search across posts and integrated apps is praised consistently. Confluence's search is its most common complaint. Neither has semantic search by meaning across all content types. Fabric does.

Is Slab cheaper than Confluence?

Similar. Slab Startup at $6.67/user/month versus Confluence Standard at ~$5.42/user/month. Confluence's real cost is higher when you add Marketplace apps, Atlassian Guard for SSO, and storage. Slab's pricing is more predictable. Fabric is $5/month flat with no per-user pricing.

What if my team won't maintain any wiki?

Then the choice between Confluence and Slab is the wrong choice. Fabric organises knowledge automatically. The AI is the librarian. No documentation discipline required.
