PoolKit is a pooling plugin from our small studio, Barbed Wire Glove Games. Swap Spawn Actor from Class for Spawn Actor From Pool and Destroy Actor for Release Actor To Pool. No manager actor, base class or interface. It also pools widgets, sounds, Niagara systems, decals and mesh components.

  • Auto-tune: play normally and it suggests pool sizes from each pool’s real peaks.
  • Debugger tab: live counts, a 30-second graph, and warnings for leaks and double releases.
  • Replicated actors pool server-side. PoolKit.Benchmark times SpawnActor against pooling on your own machine.

UE 5.4-5.8, Win64 only, source plugin (needs a C++ project). Built with AI-assisted development; 27 automation tests included.
