ThreadMine

ThreadMine turns a JVM thread dump into an answer in seconds. Paste or upload one — free, no signup — and it auto-detects deadlocks, thread leaks, pool exhaustion, CPU hotspots, and virtual thread pinning (Project Loom), with an A–F health score. The AI assistant, Vein, explains the root cause in plain language and suggests the fix. It reads HotSpot, OpenJ9, Zing and GraalVM. The thing others miss: virtual-thread pinning detection.
