A powerful Unreal Engine 5 editor plugin for profiling UObject memory usage, detecting memory leaks, and analyzing object reference graphs in real-time.
- Real-Time Monitoring — Track object creation and destruction with zero-cost incremental tracking using UE's native UObjectArray listeners
- Leak Detection — Automatically identifies classes with consistently growing instance counts
- Hot Object Detection — Highlights classes with high creation/destruction rates
- Memory Analysis — View total and average memory size per class with detailed breakdowns
- Snapshot System — Take snapshots and compare object counts over time to identify memory growth
- Reference Graph — Visualize incoming and outgoing object references with configurable depth
- Smart Filtering — Filter by category, size, source (Engine/Game/Plugin), text search, and leak/hot status
- Grouping — Group results by module or category for easier navigation
- Export — Export profiling data to CSV for external analysis
- Content Browser Integration — Jump directly to assets from the profiler
- Clone or download this repository into your project's
