Each knowledge base software in brief

1. ProProfs Knowledge Base

ProProfs Knowledge Base suits a one-person team that wants a free start and a public help centre, with 60+ languages and reader ratings available. Costs grow per author: Essentials is $49 for each. The catch: the pricing page lists approval workflow only on the top tier, and Free stops at 1 author and 25 pages.

Best for: Very small teams that want to start free and pay per author. Prices, facts and sources

2. GitBook

GitBook suits documentation teams that want a free start, Git sync, reviewer-gated change requests and a docs API. The catch is that Free is single-user and has no custom domain, and SAML SSO and visitor authentication sit on the upper plans. Its docs do not say whether the search report lists searches with no results.

Best for: Product and developer documentation teams that want change requests and Git sync. Prices, facts and sources

3. Archbee

Archbee suits product-documentation teams that want a hosted help centre with a custom domain and revision history from $80 a month. The Reviewer approval flow, search reports and translations need Scaling at $350 a month, and SAML sign-on needs a quoted Enterprise plan. There is no free plan, the page does not state how many editors the starting prices include, and the platform's source code is not among the vendor's public repositories.

Best for: Product teams that need review rules and a docs widget. Prices, facts and sources

4. Helpjuice

Helpjuice suits teams that want review and approval, SAML sign-in, an article API and a help centre on their own subdomain, and can afford a flat monthly fee. The catch is price: the cheapest plan is $249 a month, with no free plan and no certification named on the pages we read.

Best for: Companies that want an editorial review step and an API and can pay a flat fee. Prices, facts and sources

5. Document360

Document360 suits teams that want custom workflow statuses, reader-specific access and SSO for a public or private help site. It publishes no prices, so you cannot compare cost before talking to the vendor, and it shows no free plan. Its workflow docs describe no required approval step before publishing.

Best for: Teams that want custom workflow statuses, reader groups and SSO and are happy to get a quote. Prices, facts and sources

6. HelpDocs

HelpDocs suits teams that want a public help centre at a flat price, with readers never counted. It covers versions, search reports, feedback, roles and SAML or OIDC sign-in. The catch: there is no free plan, no documented named-reviewer approval step, and no SOC 2 or ISO 27001 report yet.

Best for: Small support teams that want a flat-fee public help centre. Prices, facts and sources

7. Mintlify

Mintlify suits teams that write help content in Git and want a free plan with a custom domain. Search reports and feedback need Pro at $450 a month, and role-based access control and SSO need a quoted Enterprise contract. Articles are managed through Git or the web editor, and the documented API triggers builds and reads content.

Best for: Teams that keep docs in Git and want a free start. Prices, facts and sources

8. ReadMe

ReadMe suits developer-docs teams that want a free start with a custom domain, then branches and reviews on Pro. The step from free to $250 a month is large, and roles, approval rules, translations and SAML sign-on need a quoted Enterprise plan. Access control covers the whole site rather than single sections, and its public GitHub repositories are tools and libraries, not the platform.

Best for: Developer-docs teams that want reviews and Git sync. Prices, facts and sources

9. BookStack

BookStack suits teams that can host a PHP and MySQL or MariaDB app and want a free, open-source documentation site with custom roles, SSO and an API. An admin can make the whole site publicly viewable. The catch: the pages we read show no search reports, reader feedback, help widget or approval workflow, and the project runs no hosting.

Best for: Teams that can run their own server and want a free documentation site. Prices, facts and sources

10. KnowledgeOwl

KnowledgeOwl suits small teams that want custom author roles, revision history, private articles and SAML sign-in at a public price. Basic covers one knowledge base and one author, and each extra costs more. The catch: no free plan, no documented multi-language feature, and no SOC 2 report yet.

Best for: Small teams that need roles, version review and private content. Prices, facts and sources

11. Heroic Knowledge Base

Heroic Knowledge Base suits owners of WordPress sites who want a help centre on their own domain with unlimited editors. Search reports, feedback and login-only access need Plus or higher. The catch: there is no free plan, the price doubles after the first year, and its pages do not describe an API or single sign-on.

Best for: WordPress site owners who want a help centre on their own domain. Prices, facts and sources

Every fact, side by side

Each row is one rule of the method and the points it is worth. "–" means the vendor does not publish it, which earns nothing.

Head to head

We read each vendor's own pages, record every fact with its source and date, and score it by the rules on how we score knowledge base tools. A tie goes to the lower price. Software that publishes a public help centre, knowledge base or product-documentation site. Internal-only wikis are left out unless the vendor documents a public mode. Help desks and live chat tools that bundle a help centre are not listed. Features count if offered on at least one plan; prices count one editor. Vendor claims about speed or quality are shown on product pages but never scored. Prices are in US dollars before tax.
