ThreadMine
JVM thread dump analyzer that catches Loom pinning
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.
It started as an itch: I kept reading JVM thread dumps by hand during incidents, and the worst one to catch by eye is virtual thread pinning — your Loom app quietly turns back into a bounded thread pool and nothing in the logs tells you. So I built the reader I wanted: paste a dump, get the problems named, with a health score and a shareable link.
Free, no login: upload up to 10 MB, automatic detection (deadlock, thread leak, pool exhaustion, CPU spikes, Loom pinning), health score, shareable report. Paid tiers add the AI explanations (Vein), history, multi-dump comparison and integrations.
New this week: there's an MCP server, so your coding agent can read a thread dump itself. Install:
npx @threadmine/mcp
"Why is prod hanging?" → it pulls the dump, gets the analysis back, and tells you which lock is the problem. That one surprised me — it's the use case I didn't design for and now use the most.
Straight about privacy since people ask: the dump is uploaded and processed server-side (not in your browser), over TLS, encrypted at rest, kept temporarily and deletable on demand, with zero retention on the AI side.
I'd genuinely love for you to throw a real production dump at it and tell me where it's wrong — especially edge cases in OpenJ9/Zing parsing or the pinning detector. Happy to answer anything here.
PS: `PRODUCTHUNT` takes 30% off the first payment, if you want it.
