In simple English
You describe a web application in plain chat. An artificial intelligence (a computer program that generates text and code) writes the code inside a real Linux environment (a virtual computer running inside your server). You watch the app update live in your browser. When you are happy with the result, you publish it with one click. It is free to run on your own server, but you pay for the artificial intelligence API calls you use.
What it is
An open-source web application builder powered by the Vercel AI SDK (a software toolkit for adding artificial intelligence to web apps) and Freestyle virtual machines (isolated cloud computing environments). It gives you conversational coding, live previews, terminal access, and one-click publishing.
What it is good for
Solo builders who want to rapidly prototype web applications using chat prompts without setting up development environments from scratch.
- Builds full web applications from simple text prompts in real time.
- Includes live previews and terminal access for inspecting the running code.
- Keeps all project files and conversation history saved on permanent virtual machines.
- Requires an external API key from OpenAI or Anthropic, which costs money per use.
- Needs a Freestyle cloud account and API key to manage the underlying virtual machines.
- Setup requires familiarity with Node.js and environment variables.
