Flyspray vs MantisBT

Flyspray is a free, self-hosted web bug tracker written in PHP for software development and project management. It runs on Linux and web servers and is released under the LGPL 2.1 licence. Multiple projects, task histories, comments, file attachments, voting, dependency graphs, roadmaps and task search support day-to-day issue work. Users can watch tasks and receive changes by email, XMPP or on the page. Global and project-specific roles and permissions provide customizable access control. Atom and RSS feeds, task filters and CSV export extend task handling. Optional OAuth2 single sign-on can use providers such as Facebook and Google. Flyspray 1.0 or later requires web-server software, PHP 5.6 through PHP 8.3, PHP-GD and a database such as MySQL or PostgreSQL; MariaDB is listed as a compatible variation, and Apache is officially supported. The latest listed release is 1.0-rc11, dated 29 January 2024. Development downloads may contain bugs and unintended side effects and are not recommended for production.
