Open Source ClickUp Alternative

Why choose an open-source ClickUp alternative

ClickUp packs a large feature set, including docs, whiteboards, goals, time tracking, and dashboards, into a single product, with the deeper features gated behind paid tiers and usage limits on lower plans. That breadth is useful for some teams, but it also means a lot of surface area to configure, and project data lives inside ClickUp's hosted platform regardless of which tier a team is on.

A self-hosted project management tool puts task data, timelines, and team communication on infrastructure the team controls. That matters for teams under data residency requirements, or ones that would rather run a smaller, more focused tool than manage ClickUp's full feature surface.

What to look for

Project management software needs task tracking with dependencies, a way to visualize timelines through Kanban, Gantt, or both, goal tracking tied to actual tasks, and reporting that shows where work is stuck. Since most teams don't come from a formal project management background, an interface that doesn't require PM training to use daily is worth weighing against raw feature count. Onboarding time is a real cost too: a tool that takes weeks to configure before anyone can track a single task is a poor trade even with a longer feature list.

Leantime as a ClickUp alternative

Leantime is built with PHP and designed around a lean, idea-to-execution workflow rather than replicating every ClickUp feature. It covers ideation boards, task and milestone tracking, Kanban and Gantt-style timelines, goal tracking, and time tracking, aimed at teams and non-profits that don't have a dedicated project manager. Because it's self-hosted and open source, there's no per-user fee or feature gate tied to a pricing tier: the full feature set is available in the self-hosted deployment. Leantime's workflow model starts from an idea or goal and connects it down to individual tasks, which keeps day-to-day work visibly tied to the reason it exists rather than sitting in a disconnected task list.
