Free Team Wiki and Docs Tools

Which docs, wiki and knowledge base tools a startup team can use for free today, how many members and pages the free plan covers, how much page history it keeps, whether a card is needed and what the first paid plan costs, read from each tool's own page.

Free allowances read on each provider's own pages, all checked on or after . Wiki and docs tools change their free plans from time to time: confirm the terms on the tool's page before your team moves its docs there.

Wiki and docs tools a startup team can use for free today include Slab (Free forever for up to 10 users + guests), Docmost (Free community edition, self-hosted), Confluence (Free forever for up to 10 users), BookStack (Free and open source, MIT licensed), and Notion (Free plan, limited blocks for teams). Each of the 9 free plans below links to the tool's page that states it, with its main limit, how much page history it keeps, whether a card is needed and what the first paid plan costs.

A team wiki is where a startup writes down how things work: onboarding, decisions, specs, processes. Most wiki and docs tools have a free plan for a small team, and several open-source knowledge bases are free to run yourself.

The headline rarely tells you how far it goes. A free plan can stop at a handful of users or items, cap uploads and blocks, or keep only a few days of page history. Each tool below shows what is free, its main limit, how much page history it keeps, whether a card is needed and what the first paid plan costs, quoted from the tool's own page with the date we read it.

Which tools we picked and the order they appear in are our editorial choices; the terms are the providers'. Some of these providers pay us a referral commission when someone signs up through our link: those links are labeled, and they play no part in which tools are listed or where.

Methodology

How this comparison is built

The list covers team wikis, docs workspaces and knowledge bases a founder can use for free today without applying to a program. The order and the "best for" notes are our editorial reading of each tool's terms. Every term comes from the tool's own pricing or help page on the date shown, never from a third-party list; follow each link for the full conditions. A cap on members, blocks or uploads, or a short page history, can matter more than the headline, so the comparison quotes them wherever the tool states them. Some of these tools pay StartupPerks a referral commission, and their links are labeled as referral links; that decides neither whether nor where a tool appears, and no tool pays for a placement on this page.

StartupPerks is a comparison tool and is not endorsed by the programs it lists. It is a referral partner of some providers, and those links are labeled where they appear. AITraining.jobs and Founden are run by the same company as StartupPerks: their listings are free, ranked by the same rules as every other program, and labeled "Same owner as StartupPerks" wherever they appear. Values and eligibility are aggregated from each provider's public pages and can change or be incomplete. Always confirm the current terms and your eligibility on the provider's own page before applying.
