JoinRBX · 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

Make a GET request to /public with two parameters:

                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)

📌 Try this link:

/public?placeId=15532962292&gameInstanceId=1cca5e6c-b360-47fc-bb56-de16fa13592a

→ Opens a page that auto-launches Roblox into the specified Sol's RNG server.

🔧 Deep link format (what the page triggers):

                    roblox://experiences/start?placeId=15532962292&gameInstanceId=1cca5e6c-b360-47fc-bb56-de16fa13592a
