ThreadMine

About

ThreadMine analyzes JVM thread dumps to provide answers within seconds. Simply paste or upload a dump, free of charge and without requiring a signup. It automatically identifies issues such as deadlocks, thread leaks, exhausted pools, CPU hotspots, and pinning for virtual threads from Project Loom, assigning an A through F health grade. Its AI assistant, Vein, clarifies the underlying cause in simple terms and recommends solutions. The tool supports dumps from HotSpot, OpenJ9, Zing, and GraalVM. A key differentiator is its ability to detect virtual thread pinning, which other solutions often overlook.
