Edit .lua and .luau files
Open and organize Lua and Luau source files in a multi-file code editor. The editor is designed for code review and writing, including Roblox scripting projects.
Browser-based coding workspace
Online LuaU Editor for Luau and Roblox scripts
VibeCoding By Zeox gives you a focused place to create and edit LuaU (Luau), Lua and web project files in your browser. Work in a local-first workspace with syntax-aware editing, lightweight diagnostics and optional AI assistance.
What you can do in the LuaU editor
Use one browser workspace for scripting files and related project assets, without installing a desktop editor first.
Review syntax diagnostics
Lightweight Lua and Luau structure checks help surface common syntax issues. They are not a replacement for the Roblox Luau compiler or type checker.
Keep projects in your browser
Workspace files are stored locally in the browser. Export a backup when you want to move or preserve a project.
Customize your editor
Change interface and syntax colors with custom themes, and adjust editor settings to suit your workflow.
Use optional AI tools
Connect your own Gemini or Mistral API key for development chat or code-fix requests. Your key remains in page memory and requests go directly to the selected provider.
Preview web files
For static HTML, CSS and JavaScript projects, use the built-in website preview alongside your source files.
LuaU and Luau: what to search for
Luau is the language commonly associated with Roblox scripting. People also search for it as “LuaU,” “Lua U,” or “Roblox Lua editor.” VibeCoding supports both .lua and .luau file workflows in its browser workspace.
This is an online editor, not the Roblox runtime. To run a script inside Roblox, use Roblox Studio and its supported tools.
LuaU editor FAQ
Can I edit LuaU online without installing an editor?
Yes. Open VibeCoding in a modern browser, create or import a project, and edit LuaU/Luau files in the browser-based workspace.
Does VibeCoding run Roblox scripts?
No. VibeCoding provides code editing and lightweight diagnostics; Roblox scripts must be run and tested in Roblox Studio.
Are my local project files uploaded automatically?
No. Project files are stored in this browser. If you choose an AI feature, the selected prompt and code context are sent to your chosen AI provider; otherwise, code stays local to the browser.
