Security sandbox – Prevents IP theft, malware, unauthorized distribution.
What You Can Do
Web embed – Use Roblox’s official embed widget on your site (launches in browser).
Roblox API / Webhooks – External apps can read/write datastores, trigger events.
Roblox Studio → standalone engine? – No official path. Some reverse‑engineered projects exist (Rojo for VS Code workflow, OpenCloud for server APIs) but not .EXE export.
Recreate in Unity/Godot – Port logic/assets manually if you need a distributable build.
Roblox’s terms prohibit extracting or redistributing the engine/client. Stay on‑platform.
