Real example · Build apps (vibe coding)

Vibe-coded a mini app in an hour, then needed 100 hours to ship it

Done withClaude
Free tier From $20/mo

Also used: ChatGPT، Gemini

What they did

Mac Budkowski scoped an idea with ChatGPT and built Cryptosaurus with Claude Opus: a Farcaster mini app that turns a profile picture into a dino-styled image, generated through the Gemini API, which users can mint for $2.

How it went

A working local prototype appeared in the first hour, but the finished product took about 100 hours and roughly 200 image-prompt iterations. He reports 1,000+ downloads, 180+ paid mints and a top-three place in the mini app store in week one, and puts the real speedup at 10 to 100 times.

Worth knowing

Much was manual or went wrong: a launch bug left some payments stuck and he refunded them by script, the cloud setup was overbuilt, and a browser dark-theme bug that three AI models could not fix was solved by a senior engineer in one line. Figures are self-reported.

Try it yourself with Claude

Prompt to paste
I want to ship [small app idea] to real users. Before writing code, ask me clarifying questions. Then give a one-page plan: the user flow, what data is stored, the services needed, and the three most likely failure points at launch (payments, sign-in, odd inputs).
Keep the architecture as simple as possible and tell me what you would deliberately not build yet.

Let an AI agent build a 3D museum showcase site alone

Hady Raie gave Claude Opus 5.5 (as named in his video) one prompt for a 3D interactive showcase of the Grand Egyptian Museum, and left it for about 90 minutes. It made its own plan, generated images, turned them into 3D, wrote the code, screenshotted and fixed its own bugs, and published the site.

What happens when a coding agent tries to fix a staging error alone

PocketOS, a small software firm serving car-rental companies, had a Cursor agent (running Claude Opus 4.6, per ABC News) hit a credential mismatch in staging. It chose on its own to fix it by deleting a Railway volume.
