Redmine

Project Management Free

Redmine's appeal starts with the price tag: it's free and open source, yet covers real ground — issue tracking, wikis, forums, and Gantt views — without licensing costs getting in the way. The plugin ecosystem is where it really opens up, letting technical teams bolt on the specific features they need rather than accepting whatever a vendor decided to ship. That's also exactly who it suits best: teams comfortable extending and maintaining their own tooling, since getting the most out of Redmine means treating it a bit like an internal project itself.

It integrates with Slack and Microsoft 365, with plugins extending integrations further. There's no per-seat cost to worry about, which matters for small and mid-size teams watching budgets closely.
