phpBB review: the free, open-source forum software powering thousands of communities. See features, self-hosting requirements, pros, cons and alternatives.
phpBB is free, open-source forum software originally created by James Atkinson in 2000 and now maintained by phpBB Limited alongside a large volunteer contributor community. It is one of the oldest and most widely deployed bulletin board systems on the internet, powering everything from small hobbyist communities to large support and gaming forums.
Because it is self-hosted, administrators install phpBB on their own web server and database, giving them full ownership of their community's data, moderation policies, and customization, in contrast to hosted forum SaaS products.
phpBB provides threaded discussion boards, private messaging, granular user and group permissions, a built-in search engine, and extensive moderation and reporting tools. Its styling system supports fully custom themes, and its extension framework allows administrators to add features like polls, attachments, and third-party integrations.
The platform has been localized into more than 50 languages by community translators and supports a wide range of authentication methods, including LDAP and OAuth-based logins through official and community extensions.
phpBB itself is completely free to download and self-host under the GNU General Public License. There is no official paid tier for the core software.
Costs come from external factors: web hosting, a domain name, and optional premium styles or extensions sold by third-party developers in the phpBB community. Organizations that want managed hosting typically use a separate third-party hosting provider rather than an official phpBB-branded hosted plan.

phpBB includes conversion tools for migrating from several other forum platforms, and community-built converters exist for many additional systems.
Yes. phpBB continues to receive updates from phpBB Limited and its volunteer contributor community, including security patches and new extensions.
phpBB is a traditional, self-hosted, PHP-based bulletin board, while Discourse is a more modern JavaScript-based discussion platform; phpBB tends to offer more granular self-hosted control and a larger legacy plugin ecosystem.
