Roblox Build, the company's text-prompt game maker, entered public alpha on July 28 — but only in New Zealand. It is the first time anyone outside Roblox can type a sentence into the Roblox mobile app and get back a playable game, and the company has given no date for anywhere else.
Build was announced on July 16 by Nick Tornow, Roblox's Senior Vice President of Engine, and Vlad Loktev, its Chief Creator Ecosystem Officer. The alpha is the first time it has been in public hands.
How Build works
You describe the game you want in ordinary language — the company's own example is "let's make a cozy adventure game set in a dense forest with environmental obstacles" — and Build generates a starting project. That starting point is not just a map: it covers gameplay mechanics, environments, characters, visual style, and sound.
From there you iterate. You can playtest the result immediately, ask for changes through a chat interface, share the project with friends, or move it into Roblox Studio, the full desktop editor, to keep working on it properly. TechCrunch reports that Build runs on a mix of open-source and Roblox's own proprietary AI models.
The important design choice is that all of this happens on a phone. Roblox Studio has always required a computer, which quietly excluded a large share of the platform's own users from ever making anything.
Who can use it, and who can publish
The two age gates are different, and the gap between them is deliberate:
- Age-checked users 9 and older can use Build during the alpha.
- Age-checked users 16 and older can publish what they make to a global audience.
Both require passing Roblox's age check. Published games must also clear the company's safety checks and go through the same extended review that every Roblox game faces before it enters the catalogue.
The flood problem, and Roblox's answer
The obvious risk with prompt-to-game tools is volume: if anyone can generate a game in a minute, the platform fills with thousands of thin ones. Roblox's stated answer is that generated games get no special treatment in discovery. They are ranked by the same retention-based system as everything else and compete in the same candidate pool.
The company puts it bluntly: "If no one plays it — no one can find it. The quality of games on the homepage isn't changing."
Whether that holds is the thing to watch. Retention ranking sorts what people already opened; it does not by itself stop a catalogue from becoming harder to search.
Pricing
There is a free base version, with paid options aimed at heavier users. Roblox has not published what those tiers cost or what they unlock.
More agents are coming
Build is the consumer-facing piece of a wider push. Roblox says three further AI agents are coming to both Build and Studio: a playtesting agent that hunts for bugs, an analytics agent that explains game performance in plain language, and an experiment agent for tuning engagement and monetisation.
No Philippine date yet
This one has to be said plainly: Build is not available in the Philippines, and Roblox has not announced when it will be. The rollout plan is only that it will reach "more creators and more regions over the coming months".
That is a real gap for a market like this one. Roblox in the Philippines is overwhelmingly played on phones rather than on gaming PCs, which is exactly the constraint Build is designed to remove — a mobile-first creation tool matters far more where Roblox Studio was never a realistic option. Filipino creators who want it are waiting on a regional expansion with no published schedule.
Roblox has been reshaping its feature set fairly aggressively this year, including shutting down Roblox Connect in favour of Party Voice. Build is the more consequential change: it moves the platform from hosting what creators make to generating the first draft for them.
