Another one is https://github.com/xoofx/Varena https://github.com/xoofx/Varena Arguably, there's less need for arenas in C# in most scenarios than in Go because of easy object and array pooling out of box with ArrayPool<T>, ObjectPool<T> (Sdk.Web workload) and stackalloc/InlineArray and co. You can also just use malloc/free directly with NativeMemory.Alloc/Free instead.
