Common Questions
Q: Which is cheaper—Slab or Tettra?
A: It depends on team size and needs. Tettra's Basic plan at $4/user/month is cheaper than Slab's Startup plan at $6.67/user/month, and Tettra includes AI features at that lower price. However, Slab's free plan is more capable (real-time collaboration, 90-day history) than Tettra's for teams under 10 users. For most paid use cases, Tettra delivers more features per dollar.
Q: Does Slab offer a free trial?
A: No. Slab does not offer a free trial on its paid Startup plan—it only offers a free plan capped at 10 users. You would need to commit to a paid subscription to access features like unlimited version history and advanced analytics. Tettra, by contrast, offers a 30-day free trial on its paid plans, which is a meaningful advantage when evaluating the two tools.
Q: What do you get for Tettra's $12/user Professional plan that isn't in Scaling?
A: Tettra's Professional plan at $12/user adds three things over the $8/user Scaling tier: SSO/SAML for enterprise authentication, custom branding for your knowledge base, and a dedicated customer success manager. If your team doesn't need SSO or branded portals, the Scaling plan at $8/user covers most practical needs including API access and analytics.
Q: Is Slab's Business plan worth the custom pricing?
A: Slab's Business plan adds SSO, advanced security, and dedicated support—features that competitors like Tettra include in defined paid tiers without requiring a sales call. If those features are essential, you'd likely get more transparent pricing and comparable enterprise features from Tettra's Professional plan at $12/user before reaching out to Slab's sales team.
Q: Is there a better alternative to both Slab and Tettra for teams that need more than an internal wiki?
A: Yes—Docsie addresses the core limitations shared by both tools. Neither Slab nor Tettra can convert videos into documentation, deliver content to external clients through branded portals, support 100+ languages, or provide built-in LMS and certification capabilities. Docsie's Premium plan at $199/month for 15 users includes all of these features, plus AI credits for video processing, SOC 2 Type II compliance, and multi-tenant portal delivery—making it the stronger choice for teams whose documentation needs extend beyond internal knowledge sharing.
Q: Can Slab or Tettra scale to serve external customers or multiple clients?
A: No. Both Slab and Tettra are internal-only tools with no external documentation delivery at any price point. Neither supports custom domains, white-labeled customer portals, or multi-tenant architectures. If your team needs to deliver documentation to customers, partners, or multiple client organizations, you would need to purchase a separate documentation platform on top of either tool—negating much of the cost savings from their affordable pricing.
Deep Dive
Slab wins on raw per-seat cost—$6.67/user/month (annual) is the cheapest paid tier in the internal wiki market. However, that low price reflects a stripped-down feature set with no AI, no API, and no custom branding. Tettra's $4/user Basic plan includes Kai AI and content verification, making it arguably better value despite the lower sticker price. For teams that need AI-assisted knowledge management, Tettra's $4/user delivers more functional value than Slab's $6.67/user. Both tools are genuinely affordable compared to Confluence or Notion, but you get exactly what you pay for—minimal feature sets with no external delivery capability.
Both tools use per-user pricing, which means costs scale linearly with headcount and can become expensive at larger team sizes. Slab's Business tier has no published pricing, creating uncertainty for growing teams. A 50-person team on Slab Startup pays $333/month; Tettra Scaling costs $400/month for the same size. Tettra's Professional tier at $12/user becomes $600/month for 50 users—still reasonable by enterprise standards. The real scalability concern is feature ceiling: neither tool adds meaningful capability as you spend more, and both hit a wall when teams need external delivery, multi-tenant portals, or advanced compliance features that no tier provides.
The biggest hidden cost with both Slab and Tettra is what they don't do—forcing supplemental tool purchases. No video-to-documentation capability means separate screen recording tools. No multi-tenant portals means separate customer documentation platforms. No multi-language support means separate translation services. No LMS means a separate training platform. Slab's hidden cost is its feature ceiling—teams eventually outgrow it and migrate, incurring switching costs. Tettra's hidden cost is the SSO gap: jumping from $8/user Scaling to $12/user Professional solely for SAML represents a 50% price increase just for an authentication feature. Neither tool offers a free trial-to-paid migration without credit card commitment at the same time.
