Capture Game Screen is a demonstration of recording a player’s game, not a ready-to-install anticheat. The author explicitly describes it as an example rather than an immediately usable product. Its manifest loads client.lua and a built frontend at frontend/dist/index.html.
Setup and checks
Before experimenting, inspect how capture starts, where recordings go and who can access them. Check that the frontend build exists and test only with informed participants. This source review does not establish recording retention, access controls or a completed in-game test.
