Meta's Pocket turns prompts into games, but the games never leave the app
Meta's Pocket app builds playable mobile games from text prompts in minutes, but according to Ars Technica there is no way to take a finished project outside its platform.

Meta's new prompt to game app, Pocket, will build you a working game in about two minutes flat. It will not, however, let you take that game anywhere else.
According to a report from Ars Technica, Pocket launched in the US on Friday 21 August, five months after Meta acquired the team behind the now defunct vibe coding app Gizmo. The app lets anyone type a description into a box marked “Describe an idea…” and get back a playable mobile game, called a gizmo, with no code visible at any point. Finished gizmos live in a TikTok style feed, complete with likes, comments and reposts.
The Ars Technica writer Kyle Orland tested the app for the better part of a week. His first prompt described an overhead game where holding the screen spins a sling around a character and releasing it fires a ball. Pocket delivered a functional prototype in under two minutes, and threw in extras nobody asked for, including explodable hay bale targets, a score counter and an on screen power meter.
What a hundred prompts buys you
Orland kept going. Over more than 100 follow up prompts he added marching robot enemies, new enemy types, an ammo system, then removed the ammo system in favour of a minimum sling speed, an electric fence around the player, items and a scoring system. A second project, a juggling game built around bouncing coloured balls off thumb controlled paddles, grew a similar pile of features: a multiplier system, an item pool and end of game graphs.
He describes the results as a majority of prompts landing exactly as intended, a minority needing a follow up prompt to clarify or fix a detail, and only a handful breaking the game outright, at which point a single tap reverted to the last working version. Compared with the CLI heavy, terminal based version of vibe coding aimed at people who already know their way around an IDE, Pocket strips out every barrier bar the typing.
Why the results cannot leave the garden
The catch is that Meta controls the results. Pocket's gizmos are built and hosted entirely inside Meta's platform. There is no export button, no source code to download, and no real way, as Ars Technica notes, to turn a finished gizmo into something separate from Pocket itself. Whatever Orland built over his week of prompting stays exactly where Meta wants it: inside a feed that Meta owns, subject to whatever terms and moderation Meta decides to apply next.
That matters for anyone who has watched the Gizmo acquisition play out already. Gizmo was a standalone vibe coding app until Meta bought its staff in March and folded the idea into Pocket. Nothing in the Ars Technica account suggests Pocket users get any more portability than Gizmo users did, which leaves creators building on borrowed ground. A hit gizmo, or a promising prototype worth turning into a proper release, has no obvious path off the platform if Meta changes the rules, shuts a feature down, or simply decides gizmos are not worth hosting any more.
What is still unclear
Ars Technica's account is a hands on first impression rather than a technical breakdown, so plenty is unconfirmed. There is no detail yet on what model or models sit behind Pocket's code generation, how gizmos are stored, or whether Meta has any plans to open up export options later. Nor is it clear how Pocket's moderation and monetisation will work once the feed fills up with other people's gizmos. For independent developers weighing whether easy AI prototyping is worth the trade off, the honest answer right now is that nobody outside Meta has published the terms of that trade.
