Open-source alternatives to Zapier

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

About Zapier: Proprietary SaaS; task-based pricing makes heavy automation expensive. It is closed-source, so the same public maintenance signals do not exist for it — we score only the alternatives below.
