Roblox Studio Build Roblox games
from your phone or browser
A Studio-style editor with a 3D viewport, Lua scripting, AI Builder, game templates and one-click publish to Roblox. Works on Android 8+, Windows, macOS and any modern browser.
Everything you need to ship a game
The familiar Studio workflow, rebuilt for small screens and the browser — with no install required to start.
3D viewport
Orbit, pinch and pan the camera; tap to select, then move, rotate and resize parts with touch or mouse gizmos.
Lua script editor
Write Luau-style scripts with highlighting and run them in Edit or Play mode. Full interpreter runs on-device.
AI Builder & Coder
Describe what you want — “obby with lava and checkpoints” — and build it in one tap, or let AI write the script.
12 templates + toolbox
Obby, tycoon, racing, simulator and more, plus a searchable part/model library to drop straight into your place.
Publish to Roblox
Publish through Open Cloud with your API key. Paste your game link — the Universe ID is found automatically.
DataStores built in
DataStoreService works while you test and saves between sessions. Published games use Roblox's real DataStores.
Touch controls
Play mode ships with a virtual joystick and jump button, plus keyboard controls on desktop.
Offline & private
Installs as a PWA, keeps drafts and recent places on your device, and never sees your credentials — the web build ships none.
How it works
From empty baseplate to players in four steps — your PC can be switched off the whole time.
Build & script
Assemble your place in the viewport and write or generate the Lua scripts that make it come alive.
Test in Play mode
Hit Play to walk around your own game with touch controls, watch the Output and iterate fast.
Publish
Paste your game's link in Game Settings, add your Open Cloud API key once, and press Publish now.
Players join
The game runs on Roblox's own servers — players just open your game link like any other Roblox experience.
FAQ
Do I need to verify my Roblox account?
No. There is no sign-in at all — publishing is authenticated with an Open Cloud API key (create one at create.roblox.com → Settings → API Keys with the universe-places → Write permission). No government ID, no OAuth app, no client secret.
Do I need my computer on for players to play?
No. Publishing uploads your place to Roblox; the game then runs on Roblox's servers. Your phone or PC is only needed while you're editing. This also means your home IP address is never exposed.
What do I need to publish?
Three things: an Open Cloud API key, your game's link (the app auto-finds the Universe ID from it), and a place that already exists on your Roblox account. Everything is saved in Settings → Credentials on your device.
Is it free? Does it work offline?
Yes and yes. The editor, templates and offline AI engine all work without payment or network; only AI model calls (optional) and publishing need a connection. The web app caches its shell for offline use.
