Open-source alternatives to Datadog
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 Datadog itself when the data says so.
About Datadog: Proprietary SaaS; famously large bills at scale — per-host, per-metric, per-everything pricing. It is closed-source, so the same public maintenance signals do not exist for it — we score only the alternatives below.
