I Vibe Coded a Viral Tweet App using X’s Now Open Source Algorithm

X revealed their algorithm, but nobody is using it to build. Today, we change that.

I used "Vibe Coding" in Google AI Studio to reverse-engineer the actual X Open Source Algorithm. By feeding the raw scoring logic (Heavy Ranker) into Gemini, I am building a free web app that grades your tweets before you post them—effectively "kickstarting" the viral loop using X's own rules.

I shipped the app and you can use it for free with your keys. Using the Google Gemini option is free. Access the app here: https://xoooom.com and leave feedback on x: https://x.com/vibecodewiki (the app doesn't require any auth and has no storage)

I ended up building the app with Vibe Code App: https://www.vibecodeapp.com/sign-up?code=ref-36mrjog6vsjh (Using my invite will give us both free credits)
