Vibe Coding Project Examples
Vibe coding project examples reported on Reddit: browser games, a music sequencer, a 3D scene, an iOS app and more, with the tools posters named.
Here are 10 vibe coding project examples that people reported on Reddit in the week ending Oct 15, 2026. They include browser games (a 3D survivors-style game, a 39 KB shooter, and Flappy Bird driven by CSS), a music sequencer, a 3D creek scene, a Twitch stream game, an iOS app and a movie tool. Each entry says what the poster reports building and which AI tool they name, if any. If you're after vibe coding project ideas, these show what people are attempting right now. None of them have been tested by us.

FAQ
What are good vibe coding project ideas? The posts above suggest a few starting points: small browser games, a tool for a hobby like music, a 3D scene, or an old idea of your own, like the 1987 board game. In our view, starting small and in the browser keeps the first build manageable.
Can you vibe code games? People report doing it. This week's reports include a 3D survivors-style game, a 39 KB shooter, a web board game and a driving sim. See Vibe coding for game devs.
Which tools did these posters use? Those that named one mentioned ChatGPT, Claude, Claude Code, Three.js, Meshy, GPT 6 Astra or Meta's Muse. One post, the driving sim, doesn't name a tool.
Are these examples verified? No. Each one is what the poster reports. We haven't tested them.
