Open source software development - testing
Tools and software for software testing. 7 self-hosted testing tools are listed here, ordered purely by a repository health score that Repoly recomputes nightly. Sentry Self-Hosted leads at 89/100 with 5,821 commits in the last 90 days and 46k stars, followed by Request Inbox (83) and Bencher (82). 3 of the 7 score 70 or above, 3 publish a Docker image, and the median health is 55. ⊘ Proprietary is the most common licence, carried by 3 of them. The score weighs commits in the last 90 days, release recency, stars, archive status and Docker support; a low number means low measurable activity, not low quality, so a finished, stable tool can legitimately sit lower down.

How the software testing tools compare
Sentry Self-Hosted edges Request Inbox 89 to 83, and most of the difference is stars: 46k stars against 6 stars.
The most recent release is Bencher v0.6.15, published today. None of the measured options scores under 40. By stack, Go (2), Java (1) and Python (1) are the most common. Request Inbox, Bencher and WebHook Tester are permissively licensed. Sentry Self-Hosted, BrowserStack Automate TurboScale, Bamboo and 1 more are source-available rather than open source, which limits commercial reuse. BrowserStack Automate TurboScale, Bamboo and Moon are not hosted on a forge Repoly can read, so they have no measured score yet.
