Unity Memory Profiler
Unity's official package captures and compares memory snapshots by objects, allocations, and reference chains.
Why use it
It locates unreleased assets, duplicate textures, managed retention, and peak changes between scenes or builds.
Where it fits
Use testing, performance, accessibility, and diagnostic tools to remove problems players will notice.
What to check
Snapshots are heavy and reference chains are not root causes; capture representative scenes on target platforms.
