Engine extends Roblox with custom services, systems, and packages.
The developer documentation for Engine by Arthonier. Install it once with the Studio plugin, then use ready-made services, systems and packages the way you use Roblox's own.
Server Script
local ServerScriptService = game:GetService("ServerScriptService")
local Engine = require(ServerScriptService:WaitForChild("Engine"))
local EconomySystem = Engine:GetSystem("EconomySystem")
EconomySystem:CreateCurrency("Coins", { Leaderstat = true })
EconomySystem.BalanceChanged:Connect(function(player, currency, balance)
print(player.Name, balance, currency)
end)What's inside

Quick Start
Why Engine
Built for Roblox developers
- Feels like Roblox
- Engine:GetService works like game:GetService. Names, properties and Signals follow Roblox's own style.
- Safe by default
- Session-locked data, purchases granted exactly once, remotes that validate and rate-limit, and every client request checked on the server.
- Only what you use loads
- A module starts the first time you get it. Everything you never touch costs nothing.
- Configurable, not forkable
- Every setting has a default. Change only what you need in one small module, and keep it through every update.
- Always up to date
- With automatic updates every new server runs the newest Engine. With manual updates, you choose when to move.
- Nothing to download
- Engine never comes from a website. The plugin installs it in Studio and updates arrive through Roblox.
