Open-source alternatives to Heroku
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 Heroku itself when the data says so.
About Heroku: Proprietary PaaS; killed its free tier in 2022, the canonical trigger for self-hosted PaaS searches. It is closed-source, so the same public maintenance signals do not exist for it — we score only the alternatives below.
