Plane

Plane is an open-source project management and issue-tracking tool that brings modern, streamlined planning to software teams — with the transparency, flexibility and ownership that open source provides. Often described as an open alternative to tools like Jira and Linear, Plane gives teams a clean, fast way to track issues, plan sprints and manage projects, while letting them self-host for full control over their data or use the managed cloud for convenience.

Plane covers the essentials modern product and engineering teams expect: issues with rich properties, multiple views including list, kanban board and spreadsheet, cycles (sprints) for time-boxed work, modules for grouping related work, and roadmaps to see the bigger picture. The interface is intentionally clean and quick, drawing on the design sensibilities that made newer trackers so popular, so teams get a pleasant experience rather than the bloat associated with older enterprise tools.

The open-source foundation is central to Plane's appeal. Teams that care about data ownership, privacy or avoiding vendor lock-in can run Plane on their own infrastructure, inspect the code, and shape it to their needs — while still benefiting from active development and a growing community. It's increasingly adding capabilities like analytics, integrations and AI-assisted features, expanding what it can do without losing its lightweight feel. For startups, open-source enthusiasts and engineering teams that want a capable, modern project management tool but prefer the freedom and economics of self-hostable software over closed, per-seat platforms, Plane offers a genuinely compelling option. It's one of the most promising open-source entrants in the project management space, combining contemporary design with the values of the open-source movement.
