About LoomCode AI

LoomCode AI is an open-source AI app builder. You describe an app idea in plain English; the platform generates a working application across 8 frameworks and runs it in a live sandbox you can interact with immediately.

What We Build

Most AI coding tools fall into one of two camps: code-completion assistants that live inside an IDE, or no-code builders that hide the code entirely. LoomCode AI sits in the gap between them — you describe an app in natural language, and the AI produces a complete, runnable project with proper file structure, dependencies, and idiomatic patterns for the framework you picked.

The generated app runs immediately in an isolated E2B sandbox with live preview. You can click through the UI, submit forms, watch state update, and iterate with follow-up prompts ("add dark mode", "make the sidebar collapsible"). When you're happy, deploy with one click or copy the source code into your own project. Everything is standard React, Next.js, Vue, Python, or Laravel code — no proprietary framework, no vendor lock-in.

What We Value

Open-Source by Default

The entire platform is open-source. Self-host it on your own infrastructure, fork the codebase, or contribute back. No vendor lock-in, no black-box pricing.

Bring Your Own LLM

Use OpenAI, Anthropic, Google, Mistral, DeepSeek, Groq, xAI, or local models via Ollama. Switch providers at any time without rewriting prompts.

Sandboxed Execution

Every generated app runs in an isolated E2B micro-VM. Code never touches your machine until you choose to download it.

Real Apps, Not Snippets

The output is a complete, runnable project with proper file structure and dependencies — not a single-file demo or a syntax-highlighted code block.

How It Works

When you submit a prompt, LoomCode AI routes it through the LLM you selected via the Vercel AI SDK. The chosen framework template includes system prompts, dependency lists, and file-structure conventions specific to that stack, so the model produces idiomatic code instead of generic snippets.

The generated project executes inside an E2B sandbox — a secure, ephemeral micro-VM. You get a live preview URL within seconds; the AI can also rewrite the app based on follow-up prompts. Both source code and preview persist for the session.

Frameworks We Support

Open Source

LoomCode AI is fully open-source. You can read the code, file issues, send pull requests, or fork it for your own organization. Self-hosting requires only Node.js, your LLM provider API keys, and an E2B account.
