Open-source alternatives to Trello
4 alternatives, ranked by a published maintenance score computed from live GitHub signals (fetched 2026-09-04). We flag unmaintained projects on both sides — including Trello itself when the data says so.
About Trello: Proprietary (Atlassian); free tier capped at 10 boards per workspace. It is closed-source, so the same public maintenance signals do not exist for it — we score only the alternatives below.
