AGPL-3.0
Realtime kanban board for workgroups (alternative to Trello).
Planka is an open-source task management & to-do lists project positioned as an alternative to Kanban board, with 12k GitHub stars and a health score of 80/100. It committed 252 times in the last twelve months across 11 of those months, and its status is actively maintained. Licence: ⊘ Proprietary. It has real momentum, so treat it as a live competitor rather than a stale repository.

Health score combines commit recency, twelve-month commit volume, months with activity, release recency and archive state. Metadata refreshed August 2026.
Non-standard or mixed licensing. Check the repository before commercial use.
This matters most when you plan to sell a hosted version. A permissive licence means anyone — including a competitor with more capital — can do the same, so your defensibility has to come from distribution, support or data, not from the code.
Planka is shipping code consistently, so a buyer comparing your product will find a maintained free option. Price and position against the total cost of self-hosting it, not against the paid incumbent's list price.
Winnable, but differentiation is not optional. Pick one underserved segment and be visibly better for it rather than competing feature-for-feature with a free tool.
Actively maintained. Planka recorded 252 commits over the last twelve months, with activity in 11 of those months and 14 commits in the last quarter. Last commit: 2026-08-10. Last release: 2026-08-10. Committed within the last 45 days.

Planka targets the same job as Kanban board and is actively shipping. Adoption sits at 12k stars. Whether it is a good replacement depends on your deployment constraints: self-hosting adds infrastructure, upgrade and security work that a commercial subscription absorbs for you.
24 open-source implementations, 9 of them actively maintained, led by AppFlowy at 75k stars. Saturation score 50/100 — Contested. Several maintained alternatives exist, but no one owns the category.
