AGPL-3.0
Kan is an open-source task management & to-do lists project, with 5.4k GitHub stars and a health score of 64/100. It committed 91 times in the last twelve months across 4 of those months, and its status is actively maintained. Licence: AGPL-3.0. 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.

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.
Kan 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.
