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

AI Analysis

MidShip It

White-label v0 clone that still locks you into a single proprietary backend API.

Strengths
  • Includes comprehensive features like sandboxing, database, and GitHub sync out of the box.
  • Responsive UI and artifact generation provide a solid starting point for customization.
Weaknesses
  • Not truly self-hosted since the core generation engine requires the Totalum API.
  • Competes directly with established players like Lovable and Bolt without clear differentiation.
Target Audience

SaaS founders and agencies wanting to embed AI app building

Post Description

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.

Clovr – Generate structured Next.js front ends from a prompt

Clovr trades mockup screenshots for an actual file scaffold: it claims to output a Next.js repo with a consistent design system, routing, spacing scale and readable components you could commit. That focus on structure over pixels is the right call, but the space is crowded—I'd need to see TypeScript/test support, extensibility for existing repos, and examples of nontrivial apps before I'd swap it in for templates plus Copilot.
