Analyze Java Heap Dumps Inside VS Code with AI
HeapLens is a free, open-source VS Code extension that allows developers to analyze Java heap dumps directly within their editor, without the need for a separate tool. It provides interactive analysis features powered by AI-assisted capabilities.
Why it matters
HeapLens simplifies the process of analyzing Java heap dumps, a critical task for Java developers, and integrates AI-powered analysis capabilities directly into the VS Code editor.
Key Points
- 1HeapLens brings heap dump analysis workflow into VS Code, eliminating the need for context switching
- 2It provides a multi-tab interface for overview, class histogram, dominator tree, leak suspects, and waste analysis
- 3The extension has built-in AI-assisted analysis capabilities that allow users to ask questions about the heap dump in plain English
- 4The backend is written in Rust for high performance, enabling fast parsing of large heap dumps (up to 10 GB)
Details
HeapLens is a VS Code extension that aims to simplify the process of analyzing Java heap dumps. Traditionally, developers had to generate an .hprof file, open a separate tool, wait for it to parse the data, and then navigate an unfamiliar UI to find the root cause of memory issues. HeapLens brings this workflow directly into the VS Code editor, providing a seamless and efficient experience. The extension offers a multi-tab interface that includes an overview of heap statistics, a class histogram, a dominator tree for visualizing object ownership, a list of suspected memory leaks, and a waste analysis feature that detects common memory-bloating issues. Additionally, HeapLens has built-in AI-assisted analysis capabilities, allowing users to ask questions about the heap dump in plain English. The AI-powered backend, written in Rust, provides fast parsing and analysis of large heap dumps, even up to 10 GB in size.
