LibreKB
Lightweight web-based knowledge base built with PHP and MySQL

LibreKB is a lightweight, open-source web-based knowledge base application implemented in PHP and designed to run on MySQL-compatible databases. It provides a responsive, Bootstrap-based UI and a WYSIWYG editor for creating and organizing help articles and documentation.
Key Features
- PHP/MySQL stack that installs quickly on standard web hosting or via Docker
- Responsive Bootstrap-based public and admin interface
- Rich-text article editing using TinyMCE
- Content organization with categories and subcategories and searchable index
- User accounts and predefined user groups for basic access control
- Email-based password reset and account management features
- Simple branding/white-labeling options and customizable source code
- GPL-3.0 licensed, free to use and modify
Use Cases
- Internal company knowledge base for support articles and SOPs
- Public-facing product documentation and FAQs
- Lightweight documentation portal for small teams or projects
Limitations and Considerations
- Focused on small-to-medium deployments; not aimed at enterprise-level scaling or advanced RBAC
- No built-in automatic update checks (manual updates expected)
- Integrations such as SSO/LDAP or advanced analytics are not provided out of the box
LibreKB is suitable for teams and projects that need a simple, self-hosted knowledge base with quick setup and straightforward editing tools. It prioritizes ease of deployment and basic access controls over enterprise integrations and large-scale feature sets.
