ThreadMine.dev
ThreadMine analyzes Java/JVM thread dumps in seconds. Upload or paste a dump (no signup, up to 10 MB) and get automatic detection of deadlocks, thread leaks, pool exhaustion, CPU hotspots and virtual thread pinning (Project Loom), plus a health score and a shareable report.
Parses HotSpot, OpenJ9, Zing and GraalVM. Paid plans add an AI assistant that explains the root cause and suggests a fix, multi-dump comparison/timeline, history, integrations and an API. A free, no-login web analyzer is the entry point โ the same low-friction flow as fastThread.io or jstack.review, but with automatic problem detection and AI on top.
Privacy: no account, TLS + AES-256, temporary dumps, zero AI-data retention.
