Docs and wikis

Docs and wiki tools hold a company's shared knowledge: pages, spaces and the history of who changed what. They differ less in writing than in who they bill (every member, every user, or only the people who create docs), in how much history and analytics the first paid plan keeps, and in where the admin and compliance controls start.

We compare them on the same six indicators, read from each vendor's pricing, security and help pages:

• Pricing clarity: who is billed, add-ons on separate price lists, and prices the pages leave open.
• Free tier: whether a team can share content on the free plan, how many people it allows and how much history it keeps.
• Price for 30 people, 10 who write: the lowest listed monthly cost at one stated scenario, with the assumption named where the page cannot settle who must be paid for.
• History and analytics: version history and page analytics on the entry paid plan.
• Compliance and data residency: the vendor's own SOC 2 Type II report, ISO 27001, a HIPAA BAA, a choice of data region.
• Admin control and portability: SAML SSO, SCIM, an audit log, and exporting your content in open formats.

Because the billing models differ, prices are compared at one reference scenario and the arithmetic is shown. Each review says which pages it was written from and when. Where we have run a product hands-on, the evidence is on its page.
