You may already have this. sl_bridge ships inside every ScriptLab script, and the copy you have is the one you need. This listing exists so it can be downloaded and updated on its own - there is nothing to buy.

Detected, not configured

It looks for qbx_core, then qb-core, then es_extended, in that order - QBox ships a QBCore compatibility layer, so both answer and the more specific one has to win.

It refuses to start on a guess

Find no framework and it stops there, naming the three resources it looked for and the convar that forces one. A bridge that started anyway would fail later, somewhere far less obvious.

One vocabulary for money and jobs

Scripts ask for cash, bank or black and get the right account on either framework. The same for jobs, grades, and who counts as a boss.

Inventories too

ox_inventory, the framework's own, or sl_inventory when it is running - picked in that order, behind one set of calls. Adding an item is the same line whichever is installed.

One file to fit a renamed server

Renamed your dirty money account, or your boss grades? modules/config.lua is the single place that mapping lives, and it stays readable after purchase.
