phpBB is the most widely used free and open-source forum solution.

What is phpBB?

phpBB ('BB' for Bulletin Board) is the world's most popular free and open-source forum solution. Our global community of contributors ensures that end-users receive a stable, secure, and infinitely customizable product that's easy to deploy and maintain while also being fun and simple to use.

Why choose phpBB?

Originally released in 2000, the latest version of the phpBB software has evolved to include an extensive permissions system, user groups, hierarchical subforums, file attachments, intuitive notifications, OAuth authentication, support for multiple database engines (PostgreSQL, SQLite, MySQL/MariaDB, Oracle, MS SQL Server), and a variety of other features. The phpBB Customization Database of styles and extensions offers administrators endless ability to adapt the software to their needs.

Our strict security practices have resulted in a hardened product with a proven track record greatly exceeding that of our commercial competitors. Likewise, our coding guidelines and collaborative development model ensure that code quality is a top priority while encouraging constant developer learning and growth.

phpBB and Google Summer of Code

We are proud to have participated in the GSoC program during four prior years. The goal of our mentors is to ensure that all students have a smooth and fulfilling experience. Former phpBB GSoC students have flown across the world to meet the rest of our team during our annual hackathon and have gone on to become long-term contributors to the project, some even joining the core development team. We hope that you will help us continue this excellent trend.
