Dyad AI – Free Open-Source App Builder

Dyad is a free, open-source tool that lets anyone build complete web apps using AI—no coding required. Just describe what you want in everyday language, and it turns your ideas into a working app with everything: the user interface, server side, and database.
The best part? Everything stays on your own computer for total privacy—no cloud servers involved. You own the code fully, so you’re not stuck with any company, and you can tweak or use it however you like.
It works with any AI model you prefer, whether it’s running locally through something like Ollama or connected to services like OpenAI or Anthropic. You get quick previews as you go, making the whole process super fast—often done in just minutes.
Whether you’re a beginner entrepreneur prototyping an idea, a student exploring how apps work, or a pro developer speeding things up, Dyad makes it easy and keeps your data safe.
