Docs and wiki pricing — Notion, Confluence, Slab, and the alternatives
Read-only and guest pricing dominates the bill because every employee consumes docs even when only a small team writes them.

About Docs, wiki, and knowledge base software
Docs-and-wiki is where SaaS pricing gets quietly expensive because every team needs it and most teams end up paying for two — a public-facing docs platform (GitBook, ReadMe, Mintlify) and an internal wiki (Notion, Confluence, Slab). The buying decision rarely starts as a pricing comparison; it starts as a workflow question ("do we need a separate dev-docs site?") and the pricing only matters once the workflow is set. The pages below show per-seat list across the major platforms and call out the read-only / guest pricing, which is often the dominant cost line because docs are typically consumed by a much wider audience than they're written by.

Best for
- Engineering orgs choosing a public dev-docs platform (GitBook, Mintlify, ReadMe)
- Companies replacing Confluence with Notion or vice versa
- Customer-facing teams building a public knowledge base
What to evaluate
- Per-seat list and whether read-only / guest seats are cheaper
- Public-page hosting (and whether it costs extra)
- API and Git-sync support (matters for dev docs)
- Single sign-on and audit log tier gating
Frequently asked questions
Is Notion cheaper than Confluence for a 50-person team?
Notion Plus is 10 USD per seat per month on annual billing; Confluence Standard is 5.16 USD per seat per month on annual billing at 50 seats (Atlassian's per-tier price drops as seat count rises). Confluence is roughly half the per-seat list price at this team size, but most teams pick Notion-vs-Confluence on workflow fit rather than price.
What does a public dev-docs site actually cost?
On dedicated dev-docs platforms, GitBook Plus is 65 USD per site per month plus 6.40 USD per editor per month, Mintlify is 120 USD per month for the Pro plan, and ReadMe is 99 USD per month per project. For most engineering orgs the editor count is small (5-15) but the per-project cost adds up quickly across product lines.
Do read-only docs viewers need a paid seat?
Notion and Confluence both offer reader / guest seats at a discount (Notion guests are free up to a per-workspace cap; Confluence content viewers are $0 above a base seat count on Premium). GitBook, Mintlify, and ReadMe price by editor only and include unlimited public readers. The vendor pricing pages below note the reader / guest policy on each tier.
