A FiveM script is a resource that adds gameplay to your server: a job, a HUD, an inventory, a phone, a garage or a whole police department. Every FiveM script on RPScripts lists its frameworks, dependencies and version on the product page, so you know whether it runs on your ESX, QBCore, QBOX or standalone server before you buy.
Start with the systems players use every minute, such as the HUD, inventory and phone, then add the jobs and the economy that keep them busy. Building a new server? A server pack bundles the framework and hundreds of scripts in one download.
