Scripts written against the QBCore framework, covering jobs, inventory, HUD, vehicles, admin and utilities. QBCore resources expect QB-Noyau to be present and call its shared exports, so they will not run on an ESX server without being rewritten.
Compatibility inside QBCore matters as much as the framework label. The largest split is the inventory: a script written for qb-inventaire handles item metadata differently from one written for ox_inventaire, and swapping them usually means editing every item call. Check which one a listing names before buying. Then check how recently the resource was updated against the QB-Noyau version you run, since renamed exports between QBCore releases are the usual cause of a script that loads without errors but silently does nothing.
