Live Demos
Small apps vibe-coded with Claude Code, running right here — each with the complete build log: every prompt, every bug, every correction. Try the app, read how it was made, then remix it with one copied prompt.
Tip Splitter
The classic first vibe-coding project — bill, tip, split, with honest cent-rounding. Built in four prompts.
Focus Timer
A 25/5 pomodoro timer with phase auto-switching and a progress bar — and a React interval bug the agent had to fix properly.
CLAUDE.md Generator
Answer six questions, get a ready-to-commit CLAUDE.md for your repo. The most-requested artifact from Course 01, as a tool.
Finished apps teach you nothing about the process — the learning lives in the turns: what was asked, what broke, how the correction was phrased. That loop is exactly what Course 01 drills, and these demos are the loop caught on tape. The prompt logs and source for every demo are also in the open-source repo.
