Show HN: Srcbook – Self-hosted alternative to AI app builders

Today we’re releasing a full AI app builder in Srcbook. We released our TypeScript notebook a few months ago (https://news.ycombinator.com/item?id=41291700 https://news.ycombinator.com/item?id=41291700) and the response was encouraging, but we kept hearing that people wanted to build interactive apps. Today we are releasing just that. You can think of it as an open-source and local version of vercel’s v0. We actually think of it as something in between an IDE and that, because we believe the code matters and don’t shy away from that: you can view and edit the code in a full editor, but prompt your way forward if that's what you prefer. When the AI makes changes you can review the files diff like you would a GitHub pull request, and toggle between versions to view the visual diff.
