Open-source alternatives to Datadog: which still ship
7 open-source startups in this directory are positioned against Datadog. 7 pushed code in the last 30 days, 0 have been quiet for 31–120 days, 0 have not pushed in over 120 days or are archived. “Alternative to Datadog” is a judgment by Jev, TypeSafe’s classifier, made from the repository’s own name, description and homepage, and printed only when it put that match at 0.5 or better. It is not a claim these projects make about themselves, it is not a feature comparison, and Datadog has nothing to do with this page.
Ship status
7 of 7 pushed in the last 30 days.
The list
All 7, most-starred first.
The last column is the most recent push to any branch, by a person or a bot — it is not a claim that anyone is maintaining the project, and a quiet repository may be a finished one.
