Someone just put “Minecraft” inside an X post with WORKING multiplayer. 💀
Indie builder
@jaivinwylde launched Tweetcraft: open the post, jump into a block world, explore and play with other people without downloading a game or leaving the feed.
Within hours, it had already pulled 3M+ views.
But the crazier part is how it was built:
Claude handles the game logic, persistence and multiplayer plumbing.
X provides the distribution layer.
One person + AI can now build something that once needed a small game team and instantly drop it into the timelines of millions.
Jaivin has been shipping weird consumer-social experiments for years; his site is basically a collection of internet “trinkets,” from oomfmap to Auralized, alongside his public dev work. And he’s already joking about letting brands sponsor the final boss like an F1 car.
Important caveat: this is not Mojang’s actual Minecraft client. Jaivin says Tweetcraft uses none of Minecraft’s assets and is not affiliated with Mojang or Microsoft.
Yesterday, you used a post to promote an app.
Tomorrow, the post itself may BE the app.
Games. Prediction markets. AI agents. Shopping. Multiplayer rooms. Interactive media.
If all of them can live directly inside the feed, X starts looking less like a social network and more like a distribution layer for executable internet experiences.
And AI coding changes the other half of the equation:
Idea → tell Claude → ship it → drop it into the timeline.
That’s why Tweetcraft matters far more than the Minecraft gimmick.
Now the real question:
Does this evolve into custom worlds + UGC + a creator economy… or remain one insanely good demo?
