Open-source alternatives to Figma

3 alternatives, ranked by a published maintenance score computed from live GitHub signals (fetched 2026-09-04). We flag unmaintained projects on both sides — including Figma itself when the data says so.

About Figma: Proprietary SaaS. Alternatives searched for self-hosting and file ownership, especially since the attempted Adobe acquisition. It is closed-source, so the same public maintenance signals do not exist for it — we score only the alternatives below.
