World's #1 choice for GC analysis

For those focused on industrial maintenance, several "game-style" simulators provide a realistic way to practice standard procedures.

: This is widely considered the only truly free online industrial-grade simulator. It includes a unique 6-step Lockout/Tagout (LOTO) safety training and realistic fault scenarios where you must use "all five senses" to troubleshoot. You can access it directly on the BIN95 website .

: A "full-on professional tool" that is completely free. It is the industry gold standard for power electronics and switching regulators. Download it from Analog Devices .

Many professional-grade simulation software packages offer free versions for students or hobbyists. These are "verified" in the sense that they are used by top-tier engineering firms.

: Available on Google Play , this app focuses on basic series circuits and allows users to practice 24/7 without needing a lab or expensive equipment. 2. Industry-Standard Circuit Simulators (Free Tiers)

: An ideal starting point for beginners and students. It allows you to virtually "breadboard" components, simulate microcontrollers like Arduino, and troubleshoot code in real-time.

Finding a that is verified and effective can be difficult because many high-end professional tools require expensive subscriptions. However, several reputable educational platforms and industry leaders offer powerful, no-cost tools to help students and professionals hone their skills in a risk-free environment.

How it works?

Java GC Tuning is made to appear as rocket science, but it's a common sense!

  • 1

    Enable GC Logs

    You can enable GC log by passing following JVM arguments:
    Until Java 8: -XX:+PrintGCDetails -Xloggc:<GC-log-file-path>
    Java 9 & above: -Xlog:gc*:file=<gc-log-file-path>

  • 2

    Upload GC Logs to GCeasy AI

    Upload your logs to our deterministic engine to extract 100% accurate metrics instantly.

  • 3

    Chat with GC Logs

    Ask our AI for root cause analysis, heap optimizations, and instant performance solutions.

Features

Our cutting-edge features transforms the way how engineers analyze GC Logs

Deterministic AI Engine

Proprietary engine extracts 100% accurate metrics for the LLM to interpret. This ensures conversational insights based on ground truth, not hallucinations.

Conversational Troubleshooting

Stop deciphering cryptic graphs. Chat with your logs to get instant answers to questions like "Why did my pause time spike?" or "What's the best heap size?"

AI-Powered Root Cause Analysis (RCA)

Go beyond detection to resolution. Our AI synthesizes complex data to pinpoint the exact root cause of memory leaks and latency issues instantly.

.NET GC Log Analysis (New!)

Bringing AI-powered precision to the .NET ecosystem. Analyze Managed Heaps, LOH fragmentation, and generational collection issues starting April 14th.

Node.js GC Log Analysis

Comprehensive analysis for modern JavaScript stacks. Gain deeper insights into Node.js garbage collection behavior to optimize application throughput.

Android GC Logs

Full support for all Android formats, including Dalvik and ART. Perfect for eliminating mobile stutters and optimizing device battery consumption.

Java NMT (Native Memory Tracking)

Go beyond the heap. Parse NMT output to isolate leaks in Native Memory Regions like Metaspace, Code Cache, and Direct Buffers.

JStat Analysis

The ultimate JVM utility. Analyze JStat output alongside full logs for a quick, real-time health check of your JVM's memory performance.

Online GC Analyzer

Zero friction. No registration or installation required-simply upload your log and move from raw data to AI insights in under 10 seconds.

How to enable Java GC Logging?

For Java 1.4, 5, 6, 7, 8 pass this JVM argument to your application: -XX:+PrintGCDetails -XX:+PrintGCDateStamps -Xloggc:<file-path>

For Java 9, pass the JVM argument: -Xlog:gc*:file=<file-path>
file-path: is the location where GC log file will be written

GCeasy couldn't parse my GC Logs?

We do support all of the GC log formats irrespective of the JVM version, JVM provider, GC algorithms, memory settings.

However if we don't support your format, Please report it to . We will fix it.

Can I look at sample GC log analysis reports?

Sure. Here are some sample reports generated by GCeasy:
