Plane
plane.so
Open-source project management platform — issue tracking, sprints, and roadmaps as a self-hostable alternative to Jira.
Why it is useful
Plane offers Jira's core workflow (issues, cycles/sprints, modules, views) with a noticeably cleaner interface and none of Jira's per-seat licensing once self-hosted. It's a good fit for teams that outgrew a simple kanban board but find Jira overly complex or expensive.
