Overview
LibreKB is a free, open-source, self-hosted knowledge base web application created by developer Michael Staake and first released in May 2024. It is a community-maintained project rather than a commercial company product.

Key Features
LibreKB includes a TinyMCE-powered rich-text editor for articles, role-based user groups for access control, customizable branding, and email-based password recovery, all wrapped in a responsive Bootstrap interface.
Its PHP and MySQL foundation means it can run on almost any shared hosting provider without specialized infrastructure, and Docker support is available for containerized setups.

LibreKB is completely free and open source under the GPL-3.0 license, with no paid tiers, subscriptions, or commercial edition.
Costs are limited to whatever hosting infrastructure an organization chooses to run the PHP and MySQL application on.
