Hey Product Hunt! I'm Prashant, the developer behind JVM CodeLens.
I built this because I kept running into the same problem: a JVM goes sideways in production, someone captures a heap dump and a GC log, and then the team spends hours manually analyzing them. The worst part? Even after all that analysis, the answer is usually "some code somewhere is allocating too much." Not helpful at 3 AM.
JVM CodeLens takes a different approach: real parsers extract the data, AI does the reasoning. Most "AI debugging" tools feed raw dumps into ChatGPT and hope for the best. That's fragile and inaccurate. We use proper parsers (Eclipse MAT's engine for heaps, Microsoft GCToolkit patterns for GC, JavaParser for AST indexing) to extract structured data, then send that to an LLM for root cause analysis.
The result: instead of "your heap is high," you get "SessionCache.java:142 has an unbounded HashMap growing at 2MB/min because the eviction policy was removed in commit f8a2c1d."
A few things I'm particularly proud of:
Remote JFR capture over JMX — Capture Java Flight Recorder data from a remote JVM without filesystem access. Nobody else does this.
7 automated leak detectors — Not simple threshold alerts. Statistical analysis that detects growing trends, class loader leaks, and thread growth patterns.
Holt-Winters forecasting — Predicts when your JVM will OOM, with confidence intervals. Real time-series algorithms, not heuristics.
Fully offline — Run with Ollama for air-gapped environments. Your source code never leaves your machine.
The Community tier is free forever — no trial, no credit card. I'd love your feedback on what to build next!
