Roblox Game Instance Redirector

What is this?

This service creates deep links that automatically launch Roblox and join a specific game server instance. When a user visits your link, they're redirected to a page that triggers the roblox:// protocol, instantly opening Roblox to the specified place and server.

How to use

https://join-rbx.vexsys.site/public?placeId={placeId}&gameInstanceId={gameInstanceId}

Parameters:

placeId — The Roblox place/game ID (e.g., 15532962292 for Sol's RNG)

gameInstanceId — The specific server instance UUID (e.g., 1cca5e6c-b360-47fc-bb56-de16fa13592a)
