Mergic ingests your Datadog, Sentry, PagerDuty, and OpenTelemetry — so every PR review reasons about real blast radius, latency regressions, and the incidents that happened the last time this code path changed.
Mergic’s reranker is trained on millions of historical PR comments labeled by whether they correlated to a real production incident. Findings are prioritized by likelihood of breaking production — not by where they fit in a checklist.
Error rates, latency, and saturation pulled in for every changed code path.
Recent exceptions on the path you’re changing — flagged in the review.
Past incidents tied to the code path — so the reviewer knows what broke last time.
Vendor-neutral trace ingestion. Honeycomb, Grafana Cloud, Tempo all supported.
Quantifies how many services, customers, and on-call rotations a PR could affect.
Ingests your incident postmortems and flags PRs that repeat past failure modes.
If a function caused an incident in the last 90 days, Mergic flags every PR that touches it — with a link to the postmortem, the responsible commit, and the patch that resolved it.
