Heaplight · Memory Keeper
Trace the objects a program still needs, sweep unreachable cycles, compact survivors and repair moved references across eight memory puzzles. Original responsive interface and challenges, hints, undo and local progress. Browser adaptation of gc-viz mark/sweep/compact algorithms; a simplified learning toy, not a real runtime heap monitor.
