BookStack: An Open Source Alternative to Confluence
Free and Open Source
BookStack is 100% free to use under the MIT license. The code is fully open; Use and modify BookStack any way you like, just provide attribution if you distribute the code.
Self-Host However You Please
There's no push to the cloud here unless that's your preference. Whether you install on a Raspberry Pi, or stick it in AWS; It's fully up to you. You can ensure your documentation stays behind your firewall.
Lightweight and Speedy
Tired of seeing placeholder content while your pages load? Tired of managing bloated Java processes? BookStack is built in modern PHP and can run on lightweight systems.
WYSIWYG Editing Experience
BookStack uses a WYSWIYG editor at it's core, with a range of essential formatting options and features. No scary mark-up language. Ideal for mixed-skill environments.
Standard Content Storage Format
BookStack primarily retains content in a relatively focused and flat layer of HTML. One of our ideals is to keep the format relatively standardised for if you ever need to migrate away from BookStack.
Our growing REST API allows the programming of automation where desired, and provides a mechanism for import where needed.
An Open Community
Whether it's via GitHub, Discord or our subreddit, you can discuss with and seek help from the BookStack developers & the wider community.
Diagrams.net Integration, Built In
Want to create diagrams in your documentation? You can jump directly into an embedded diagrams.net editing session which will save directly into BookStack.
A range of authentication options and controls are built-in including LDAP, SAML2 and a range of OAuth clients. Additionally MFA with role-based enforcement can be used with any of these.
