Runtime diagnostics & CI gates for Spring Boot
5 followers
WireDoctor is a runtime diagnostic tool for Spring Boot. Add one dependency and it hooks into your app's real, resolved ApplicationContext at startup, no server, no dashboard.
It shows beans on your startup critical path, catches cycles Spring silently tolerates, flags beans that cost startup time but are never used, and catches silent autoconfig changes across Boot upgrades.
In CI: commit a baseline, fail the PR that adds a new cycle or a startup regression.
Boot 2.7-4.1.x, Java 17/21/25.
I'm Deendayal, and I built WireDoctor after one too many "why does this service suddenly take 40 seconds to boot?" debugging sessions. Spring Boot's Actuator gives you raw StartupStep JSON, but nobody ships the analysis layer on top of it so you're left manually digging through logs.
WireDoctor fixes that. Add one dependency, and at startup it hooks into your real, resolved ApplicationContext and turns it into:
🔍 An interactive HTML report searchable dependency graph, real per-bean startup timings, no reflection heuristics
🚨 Cycle detection with fix advice Tarjan SCC finds silently-resolved bean cycles and ranks which @Lazy would break them
👻 Ghost bean detection finds beans that cost startup time/memory but show no sign of use (honestly labeled, never overclaimed)
🛡️ CI gates commit a baseline, and any PR that introduces a new cycle or startup-time regression fails the build automatically
It's zero-intrusion (no dashboard server), runs fully offline, and works across Boot 2.7 through 4.0.

Would love your feedback especially from anyone running large Spring Boot monoliths where startup time and hidden architectural debt are real pain points. Happy to answer any questions! 🙏
