Slab

Slab launched in 2016 aimed squarely at teams frustrated with Confluence's clutter and the chaos of a free-form Notion wiki. Its pitch is simple: a knowledge base that's a joy to write in and easy to keep organized. For internal documentation at growing companies, Slab hits a sweet spot that's surprisingly hard to find.

What Makes Slab Special

The editor is the first thing you notice. It's clean, fast, and gets out of your way — closer to a polished document editor than a clunky wiki form. The second thing is structure: Slab organizes content into Topics rather than deeply nested page trees, and a post can live under multiple topics. That keeps things findable without the rigid hierarchy of Confluence or the sprawl of Notion. Unified search is the third pillar — Slab searches not just its own content but connected tools like Slack, Google Drive, GitHub, and Asana, so it becomes a front door to all your team's knowledge.

Day-to-Day Experience

Writing in Slab feels good, which sounds minor but matters — people document more when the tool isn't fighting them. Verification flags let you mark posts as current, and analytics show what's read and what's ignored. Integrations are well done: paste a Slack link and it unfurls, embed a Google Doc, reference a GitHub PR. The reading experience is just as clean as the writing one. It's the kind of tool where onboarding a new hire to "go read these topics" actually works.

The Honest Trade-offs

Slab is internal-only — there's no public help center, full stop. It's also not cheap: the Startup plan is around $8 per user per month and Business around $15, which puts it above Confluence per seat. The topic model is elegant but less powerful than database-driven structures if you need filtered views and metadata. It's a focused tool, so no project management or ticketing. And the integrations, while polished, are fewer than the Atlassian Marketplace offers.

Who Should Choose Slab

Slab is for startups and mid-size companies that care about documentation quality and want their team to actually enjoy maintaining the wiki. If Confluence feels heavy and Notion feels messy, Slab is the middle path. It's especially good for engineering and product teams that value a clean editor and unified search. Skip it if you need a customer-facing knowledge base or a tight budget rules out per-user pricing at this level.

Pricing and Value

Slab has a free plan for small teams (up to 10 users with limited posts), a Startup plan around $8 per user per month, a Business plan around $15 per user per month, and custom Enterprise pricing. The free tier is a real way to try it. For a 40-person team on Business, that's roughly $600/month — more than Confluence, but the writing experience and unified search are what you're paying for, and for doc-heavy teams that trade-off is often worth it.
