Hi Product Hunt 👋
I’m App君, the maker of Doufu.
I built Doufu because I wanted a simple way to “vibe code” small web apps directly on an iPhone—without setting up a dev environment, opening a laptop, or deploying anything just to test an idea.
With Doufu, you can describe an idea in natural language, let an AI coding agent create or modify the local HTML/CSS/JS project, preview it instantly, edit files manually, restore checkpoints, and share the result as a `.doufu` / `.doufull` package.
A few things I care about deeply:
1. **Local-first creation** — projects run locally on your iPhone.
2. **Bring your own model** — use Codex subscription, OpenAI-compatible APIs, Anthropic, Gemini, OpenRouter, or your own provider.
3. **Transparency** — Doufu is open source, and credentials are stored locally in Keychain.
4. **Tiny creative tools** — I want people to quickly make personal tools, prototypes, interactive notes, landing pages, toys, and experiments from anywhere.
Doufu is still early, and I’d love your feedback:
What would you build on your phone if making a small web app felt as easy as sending a message?
been looking for apps like this for a while-- love building things on phone!
