“UIDrop, my design system chrome extension and my first project built with the help of Claude, just hit 10.000 users.”
Editor's note: The founder is a 20-year-old in Romania who builds in public as tudorbuildsai. He says he had given up on coding and didn't want to use AI, then "picked up some tools like Cursor to try stuff out" and made UIDrop (Oct 20, 2026), which he calls his first project built with the help of Claude. He doesn't say how much of the code AI wrote. His second app, Notch, has $88 in Polar-verified sales on TrustMRR. His X bio links uidrop.site, and TrustMRR links the listing to the same account.
How they got customers
A free Chrome extension aimed at vibe coders and frontend designers, promoted on Reddit and X (the two channels on its TrustMRR listing), with growth through the Chrome Web Store. He planned launch-directory listings and a Product Hunt launch for his next app based on what he learned from UIDrop.
Steps to try
Build for people already using AI tools: UIDrop turns a site's design into a prompt for Claude, Cursor or Lovable.
From the sourceA free Chrome extension can reach 10K+ users fast through Reddit and X.
From the sourceUse what you learn from the first launch on the next one; he lined up launch directories and Product Hunt for his second app.
From the sourcePrice for the value, not the install count: 12K users at a $4 one-time upgrade produced $115, so a recurring plan or higher price is the obvious test.
