Common reasons people leave DeepSource: private repositories need a paid per-user plan after the trial, and AI review is metered separately on top of seat pricing. We ranked 7 alternatives by how directly each one replaces DeepSource, then by reviews, real visits and how recently each app's facts were checked against its own website. SonarQube currently ranks first.

DeepSource has been acquired. DeepSource has joined Harness, according to a notice on the DeepSource website.
