FROGLOGS is the tool I use to debug and test Roblox games. It also has a whole chat, user and key system. As I wanted to expand upon it, users can type in chat, and you can join the user through their chat message directly.

Automatic game details finder, like placeid, universeid, how many players in game, max players, the server IP and location.

It will also automatically find subplaces, and you can join through this UI.

It doesn't read/write memory in any way and using imgui was a personal preference. This could have been done in any language but I wanted to use C++ for fun.
