RBX Editor

RBX Editor is a free Luau editor that runs in your browser. It autocompletes the whole Roblox API (every class, property, method, event and enum) and executor functions like hookmetamethod, getgc and request, with their signatures, so a script can be written without looking anything up.

Files save in this browser, with no account. Attach a game from your executor and Run sends the script into it, with its print and warn output coming back here. Modules you write can be required from any script.

The Assistant on the right edge runs on your own AI key (OpenAI, Anthropic, Google, OpenRouter, or a model you host) and can read, fix and test the script you have open. How the editor works · The assistant · Ember UI library
