Jira can model almost any process you throw at it - agile boards, custom workflows, fields, permission schemes, release planning - and for a large org that depth is the point. But that same flexibility is the complaint you hear most: configuring it well is close to a full-time job, screens get heavy, simple changes route through an administrator, and small teams end up paying in friction for power they never use.
The open source trackers below keep the parts people actually rely on - issues, boards, workflows, integrations - with far less ceremony to set up and maintain. Self-host them and your issue history sits in a database you control, reachable through open APIs and easy to back up or move whenever you need to.
