Show HN: Open-source AI app builder you can embed into your own SaaS

https://github.com/totalumlabs/ai-app-builder-open
5•francescjuille•3h ago
We just open sourced a first class our AI web app builder.

Instead of using another hosted AI coding platform, you can fork this project and build your own AI app builder, fully customized and running under your own brand.

It includes:

Next.js + TypeScript AI chat with streaming Artifact generation File explorer Code editor Live preview Databases Sandboxes to be used by AI agents Versions Responsive production-ready UI And a lot more...

The only required dependency is the Totalum API, which exposes the AI generation engine through a simple REST API. You can replace or extend the backend however you want.

It's designed for developers, SaaS companies and agencies that want to:

Build their own AI app builder Add AI app generation to an existing product Create a white label AI builder Customize every part of the UI and workflow Self host the frontend

We use the same frontend in production, and decided to open source it so others don't have to start from scratch.

Repository: https://github.com/totalumlabs/ai-app-builder-open

I'd love feedback, feature requests, or ideas from the HN community.
