More builders are shipping small, playful web projects through vibe coding—quick experiments made with Cursor, Claude, Bolt, and similar tools. They are rarely polished SaaS products; the point is that they are fun enough to make a stranger click. Here are five worth a few minutes of your time.
HowToWhistle: Real-Time Whistle Practice in the Browser
https://howtowhistle.org/
HowToWhistle lets you practice whistling along with songs while a live pitch line shows every note you hit or miss. After each run it marks what was on pitch and what drifted. There is a song library, a range test, daily challenges, and leaderboards—all free, no account required. Allow microphone access (HTTPS only); headphones help keep the metronome out of the mic.

Move with WASD or arrow keys, tap Space to squeeze aboard, and survive 34 stations—each with its own crowd gimmick. Miss a train and you lose three minutes.
Birthday Cake Online: Blow Out Candles with Your Mic
