Hey PH 👋 Solo maker here. Every chat app ships with the UI someone else chose. foomchat's bet is that the app itself should be part of the conversation: ask for a feature and the AI writes it — real HTML/CSS/JS — as a card you install with one click. It mounts into the live app instantly. No extension, no reload. The catalog has 22 features in it and I wrote the code for none of them — I asked for every single one. Zen mode, conversation search, export to markdown, a prompt library, keyboard shortcuts, message timestamps. Then, to find the edges: an LSD Simulator with a dose slider that progressively melts the entire interface, and a fully playable Flappy Bird. Both took one sentence each. That's the honest state of it: I'm the only person who's really used this yet. It launched a week ago and it's early. Features are versioned and can depend on each other, like tiny packages. Publishing goes through review before anything reaches other people — installed code runs in the page, so the catalog stays hand-checked until it's properly sandboxed. That's the top item on the roadmap and I'd rather say it out loud than have it found. Free credits on signup, no card, or bring your own OpenRouter key. What's the first thing you'd ask your chat app to become? I'll be here all day building the good ones live. 🛠️
