HeapLens

Visualize memory allocation patterns to pinpoint leaks in long-running processes

Code & DevelopmentFreemium

HeapLens captures heap snapshots from long-running processes and generates visual allocation timelines that highlight objects surviving beyond expected lifetimes. The tool identifies retention chains showing why leaked objects cannot be garbage collected, groups leaks by allocation site, and estimates memory waste rates per hour. SREs use it to diagnose production memory growth while developers use it during load testing to catch leaks before deployment.
