AI tools that make Roblox games, compared

Most AI tools for Roblox either work inside Roblox Studio on a computer, or build in the browser and hand you a file to publish from Studio. Two publish the game for you with no Studio at all. Roblox Build does it in a limited alpha inside the Roblox app, and studs.gg does it in any browser, phone included.

Last checked 13 October 2026. We make studs.gg, so every claim about another tool links to that tool’s own page or to Roblox.

Made by Roblox

Builds in the browser

  • studs.gg

    Builds and playtests the game, then publishes it to your own Roblox account. A one-time sign-in to Roblox sets up five empty games on your account and a publishing key limited to them, so you never create or paste a key. Works the same on a phone.

    How credits workChangelog

  • PromptBlox

    Builds in a browser chat, phone included, then hands you an .rbxlx file. Its own guide says you finish the game in Roblox Studio on a computer. An optional direct publish needs a place you already own and your own Open Cloud API key.

  • Obby

    Builds a game with a preview in the browser, then exports a standard .rbxlx file that you open in Roblox Studio and publish from there.

  • LevelShaper

    Designs and previews the game in any browser, then you download an .rbxlx file. Its FAQ says opening the file needs Roblox Studio on a Windows PC or Mac, and you publish from there.

  • Roblox AI (Robcel)

    One product under two names, robloxai.net and robcel.com. It builds in the browser and gives you a place file to open and publish in Roblox Studio. Downloading it needs a paid plan.

  • Player.games

How we checked

We read each tool’s own homepage, docs and pricing, and Roblox’s documentation for its tools. “Needs Studio” means Roblox Studio on a computer is needed at some step between your idea and a live game. A cell we could not confirm from the tool’s own pages says Unverified. Something out of date? Email support@studs.gg and we will fix it.

Questions

Which AI tools can publish a Roblox game from a phone?
Two, as of this check. studs.gg works in any phone browser and publishes to your Roblox account. Roblox Build does it inside the Roblox mobile app, but it is a public alpha open in a limited set of countries to age-checked users. The other browser builders let you start on a phone and finish in Roblox Studio on a computer.
Can I make a Roblox game with AI without Roblox Studio?
Yes, with studs.gg or Roblox Build. Most other browser builders, such as PromptBlox and Obby, build without Studio but hand you an .rbxlx file to publish from Studio. Studio plugins such as Rebirth, Ropilot and SuperbulletAI need Studio on a computer throughout.
What is the difference between a browser builder and a Studio plugin?
A browser builder makes the whole game from your description on its own servers. A Studio plugin is an assistant inside Roblox Studio. It edits the place you have open, and you stay in Studio to test and publish. Plugins suit people who already use Studio; browser builders suit people who do not.
How is studs.gg different from Roblox Assistant?
Assistant helps you build inside Roblox Studio, one request at a time. studs.gg builds the whole game for you outside Studio, playtests it, and publishes it.
