Slab plans, side by side
Every published tier in ascending order of price, with the number of features each one lists. An absence here means the record does not itemise it, not that the tier lacks it.
| Plan | Price | Features listed | Step up from the tier below |
|---|---|---|---|
| Free | Free | 4 | Entry tier |
| Slab | On request | 5 | Priced on request |
What each tier adds
The set difference between each tier's feature list and the one beneath it. Where a tier lists nothing new, the vendor has either stopped repeating the inherited list or the tier raises limits rather than adding capability, the record does not distinguish the two, so this page does not either.

What the product covers
The full Slab feature record, grouped as the catalogue groups it. This is the product as a whole; the record does not map every feature onto a specific tier.

- Quill editor
- Permissions
- Free tier for small teams
People bring Slab in for building an employee handbook and onboarding path that new starters can actually find, replacing a folder-based wiki where nobody agrees which folder a document belongs in, companies whose knowledge is already spread across drive, slack and github and needs one search box, documenting process and decisions for teams that do not want a project management tool attached. If that is not the job you are buying for, the alternatives to Slab are worth a look before you commit to a tier.
How that compares in Documentation
Too few documentation tools in this directory publish a starting price to quote a meaningful median, so the table below is a like-for-like list rather than a ranking.

| Slab (this page) | Free | Per user per month | - | |
| Paligo | On request | Per author seat per year | - | vs Slab |

| HelpDocs | On request | Per editor seat per month | - | vs Slab |

Ratings are aggregated from third-party sources and imported with each catalogue entry, they are not reviews hosted on Softwr. How each figure is used is set out on the Slab badges page.
Before you pay for Slab
Three things this page cannot tell you, and all three change the bill. The record carries a price and a billing period but not the unit - per-seat and flat-rate pricing are indistinguishable in this data, so a five-person team may be looking at five times the figure above. It carries no annual rate, so any discount for paying yearly is not something this page can quote. And it carries no trial length.
What it can tell you is the shape of the ladder: 2 tiers between Free and On request, with the jump itemised above. Because there is a free tier, the cheapest way to answer the rest is to use it before paying anything.
Slab runs on web, and is published by Slab of San Francisco, California, United States. The full record is on the Slab review, and the rest of the category is under best documentation tools.
