Wave is an external Roblox script executor built around a multi-tab code editor. Each tab keeps its own script, execution history and editor state, and the built-in browser indexes scripts by game so a payload can be located and run without pasting from a separate window.
The executor monitors the Roblox process and can attach automatically when the client starts. Output from print and error calls is mirrored into a console tab with timestamps, and execution can be queued so that multiple scripts run in a defined order.
