I built HeapLens because analyzing heap dumps in 2026 still means switching to Eclipse MAT or other desktop tools. As a Java engineer working with production systems, I wanted something that lives right where I code. HeapLens opens .hprof files natively in VS Code. The part I'm most proud of is HeapQL, a query language I designed specifically for JVM memory. Instead of clicking through object trees, you write queries to find exactly what you need. It also supports LLM powered analysis. You can connect any provider or run models locally so nothing leaves your machine. Would love feedback from anyone who works with Java in production. What would make this more useful for your workflow?
