Find the exact line of code
crashing your JVM
A JVM profiler that analyzes heap dumps, GC logs, thread dumps, and JFR recordings — then correlates every finding to your source code and uses AI to tell you exactly why and how to fix it.
No agents to install. No cloud data upload. Runs entirely on your machine.
Heap Visualizer
LIVE ATTACH: JVM PID 4102
AI REASONING
Leak in SessionManager.java:84.
GC Pauses
Threads
Real-time profiling, AI diagnosis, forecasting, fleet monitoring, and more.
Claude, Gemini, OpenAI, or fully offline with Ollama. Your choice.
Automated pattern matching for growing collections, class loader leaks, static accumulation, and more.
Source code never leaves your machine. Bring your own API key or run air-gapped.
44 Features. Zero Guesswork.
From real-time profiling to AI-powered root cause analysis — everything you need to diagnose, predict, and fix JVM performance issues.
Diagnose
Find the Exact Allocation Site
Don't just see byte[] taking 2GB. See SessionCache.java:142 is the leak. Every heap object traced to its source line.
AI Reads Your Flight Recordings
Upload a .jfr file. Get a plain-English diagnosis in 30 seconds — with fix suggestions pointing to your code.
Native Memory Tracking
Off-heap leaking? Track metaspace, direct buffers, code cache, and compiler memory with NMT analysis.
Spot Deadlocks Instantly
Interactive thread galaxy and state analysis. Click any frame to jump to source. Lock contention highlighted automatically.
AI Intelligence
AI Diagnosis & Chat
Ask the AI about your JVM. Get streaming conversational diagnostics with full context of your metrics, heap, and threads.
8 Leak Patterns, Zero Manual Work
Automatically detects growing collections, class loader leaks, static accumulation, thread-local leaks, and 4 more.
What-If Simulation
What happens if you double -Xmx? Change GC algorithm? The AI predicts the outcome before you touch production.
Incident Reports
Generate a formal RCA document with timeline, diagnosis, findings, and recommendations. Export as PDF or HTML.
Predict
Predict Before It Crashes
Holt-Winters forecasting predicts OOM and CPU exhaustion hours ahead. Get alerts before PagerDuty fires.
SLA & Error Budget Tracking
Set uptime and performance targets. Track budget consumption in real time. Get warned before you breach.
Anomaly Detection
Sigma-based baselines learn your JVM's normal behavior. Get alerted when metrics deviate — before users notice.
MTTR Prediction
How long will this incident take to resolve? Historical pattern matching estimates resolution time.
Operate
Fleet Dashboard
Monitor 50+ JVMs at once. See top consumers, correlated anomalies, and causality chains across your microservices.
Alert Rules & Webhooks
Custom threshold alerts with Slack, Discord, and PagerDuty integration. HMAC-signed for security.
CI/CD Performance Gate
Run headless in your pipeline. Fail builds when heap growth exceeds thresholds or GC throughput drops.
Time-Travel Recordings
Capture .lens sessions and replay them later. Share with teammates. Debug production issues from your desk.
From Alert to Root Cause in 90 Seconds
Watch how JVM CodeLens traces a memory leak from PagerDuty alert to one-line fix.
Alert Fires
JVM CodeLens detects heap usage at 92% and fires a threshold alert.
AI Analyzes
Within 30 seconds, AI identifies the root cause across heap, GC, and thread data.
Git Correlation
Automatically traces the leak to the exact commit that introduced it.
Fix Suggestion
AI generates a code-specific fix with file path, line number, and before/after diff.
