What is ESX in FiveM?
ESX (now maintained as ESX Legacy) is the oldest of FiveM's three mainstream roleplay frameworks, and has the deepest accumulated ecosystem of resources, tutorials, and experienced server operators. It uses a single-job player model built around an xPlayer object, with money split across cash, bank, and black_money accounts. Choosing ESX means the widest availability of long-established resources, alongside the heaviest legacy conventions to work around.

The longer answer.
ESX predates both QBCore and Qbox and carries the deepest body of accumulated resources, forum knowledge, and server operators who know its quirks. Its player object, retrieved via ESX.GetPlayerFromId(source) or the shared object export, models money across three accounts by default — money (cash), bank, and black_money — a convention that scripts written for other frameworks have to map explicitly rather than assume.
Unlike QBCore and Qbox, ESX has no native concept of a gang alongside a job; a player has one job. Resources that need gang-like behavior on ESX typically emulate it through a second job slot or a bolt-on resource, and a bridge layer should document that as a real capability gap rather than quietly pretending gangs work identically across all three frameworks.
ESX's age is both its strength and its cost: the resource and tutorial ecosystem is the deepest available, but internals and conventions have accumulated over more years than QBCore's or Qbox's, and "works with ESX" claims deserve the same scrutiny as any other framework claim — ask which ESX version and which inventory system (ESX's own, or the now-common ox_inventory) were actually tested.
