MergeSentry

MergeSentry is a web app (with optional GitHub/GitLab app integrations) that acts as a “merge gate” focused on catching risky pull requests that standard CI often misses. It analyzes PRs for blast radius (which services/modules are touched), dependency impact, test coverage deltas, flaky-test history, and past incident correlations to produce a simple risk score and required checks. Teams can define policies like “high-risk PRs require two senior approvals and green integration tests” without building custom scripts. It also auto-generates a concise PR summary and review checklist to reduce reviewer fatigue. This is a combination traditional + AI app: deterministic rules and repo metadata drive the gating, while an LLM produces summaries and suggested review focus areas. The goal is fewer regressions and faster, more confident merges—especially in monorepos and microservice-heavy orgs.
