Slab publicly shows annual billing for the paid Startup and Business tiers, while the Free tier is available forever with no credit card required. The pricing page says Startup is free for non-profits and educational use, and it offers a 30-day money-back guarantee. User billing is based on the number of users who can log into Slab, admins can deactivate users at any time, and Enterprise pricing is quote-only with sales contact required.

Pricing FAQ
Yes. Slab says it is free forever for up to 10 users and guests, and the pricing page says no credit card is required to get started. The free tier includes core collaboration and search features, so teams can evaluate the product before committing to paid seats. If a team stays under the free limits, it can keep using Slab without paying.
Yes. Slab says its Startup plan is free for non-profits and educational use. The pricing page instructs users to register for a free account and then request the discount, which indicates the discount is not automatically applied at checkout. No other public discount structure is disclosed on the provided pricing page.
Slab says you are billed for the number of users who can log into Slab. It also says admins may deactivate users at any time, which matters if you want to control seat count as your team changes. Guests are treated separately from regular users and have their own per-user allocation limits on the public plans.
No. Slab lists Enterprise as custom and provides a sales email instead of a public price. The tier requires contacting sales, and the page also shows a minimum of at least 100 users. That means enterprise buyers should expect a quote rather than a self-serve checkout price.
