2 Elixir templates

Build Elixir apps with AI

A Phoenix app on the BEAM with LiveView included and no database required to start. Describe the screens and the builder writes the LiveViews; mix is in the terminal.

Phoenix with LiveView — real-time UI without a JavaScript framework
A Phoenix AI SaaS starter with Supabase sign-in, AI chat and knowledge search
Elixir, which most AI app builders do not offer at all

The Elixir templates

Start opens the New Web App dialog with the template picked — you set the stack, design, model and MCP tools there.

  • Phoenix

    A Phoenix web app on the BEAM — LiveView included, no database required.

    Framework docs
  • Phoenix AI SaaSAI SaaS

    An AI SaaS dashboard: landing, Supabase sign-in, AI chat with history, MCP tools and knowledge search.

Every Elixir project gets

  • A cloud sandbox with a live preview of the running app
  • A real terminal with 15 coding CLIs — Claude Code, Codex, Cursor CLI, Gemini CLI and more
  • AI on your own keys from 24 providers, billed by the provider at cost
  • Its own GitHub repository from the first push

Where it can go

Vercel has no Elixir runtime, and Phoenix holds long-lived WebSocket connections, so it is not deployed there. Push to your GitHub repository and deploy to a host that runs a persistent BEAM process.

Questions

Can I build a Elixir app with AI?

Yes. Pick one of 2 Elixir templates — Phoenix and LiveView — and describe what you want. The builder writes the code in a cloud sandbox with a live preview and a real terminal, using your own AI provider key.

Where can I deploy a Elixir app built here?

Vercel has no Elixir runtime, and Phoenix holds long-lived WebSocket connections, so it is not deployed there. Push to your GitHub repository and deploy to a host that runs a persistent BEAM process.

What happens when I press Start?

You sign up — or, if you are already signed in, go straight on — and the New Web App dialog opens with that template picked. Set the name, stack, design, model and MCP tools there, then press Create.

Do I own the code?

Yes. The project is pushed to your own GitHub repository, and you can open a terminal on it at any point.
