MyBB

MyBB is an open-source forum software used for building and managing online community discussion boards. It provides a structured environment for threaded conversations, allowing administrators to organize topics and manage user interactions within a web-based interface. The software focuses on providing a stable platform where users can register accounts, start new discussion threads, and reply to existing posts in a categorized format.

The application is written in PHP and is deployed as a server-side web application. It requires a database backend to store forum posts, user profiles, and configuration settings, making it suitable for hosting on standard web servers. Because it is self-hosted, administrators maintain full control over their data and the specific configuration of their community environment, from user permissions to the overall board structure.

Key features

• Support for MySQL and MariaDB databases
• Support for PostgreSQL databases
• Support for SQLite databases
• Plugin system for adding new functionality
• Theme system for visual customization
• Translation support for multi-language boards
• Dedicated administration interface for board management

The software architecture relies on a PHP core that interacts with the chosen database system to serve dynamic content to the browser. Users can extend the base installation through a variety of community-provided resources, including plugins and themes, which allow for the modification of both the logic and the appearance of the forum. The project includes a dedicated system for vulnerability reporting and security research to ensure the stability of the production-ready versions. Detailed documentation is provided for administration, usage, and troubleshooting to assist with the setup and maintenance of the server.

MyBB is designed for community managers and developers who require a self-hosted platform for structured social communication. It provides the necessary tools to scale a discussion board from a small private group to a larger public community while maintaining ownership of the underlying infrastructure.
