Tomosu

AI now writes 30-60% of code at modern engineering teams, but the same fragile files keep causing the same incidents, and nobody's tracking it. Tomosu scores every PR against your repo's own incident history (not generic lint rules) so you catch risk before it ships. Free self-hosted edition connects to your real GitHub repos in under 10 minutes, no credit card, no sales call. Built by a former Oracle/Hortonworks support engineering lead who got tired of watching incidents recur.
