In plain English

Dyad is a local, open-source AI app builder that runs entirely on your own machine, a desktop alternative to cloud-based tools like Lovable, v0, Bolt, or Replit. Instead of sending your project to a third-party server, Dyad runs locally, so your code stays private and you are not dependent on any vendor's infrastructure. You supply your own AI API keys (supporting providers such as Anthropic and Google Gemini), which means you pay only for what you use and there is no Dyad subscription. It runs on Mac and Windows with no sign-up required, and its core is open-source under the Apache 2.0 license. It is aimed at power users who want the convenience of an AI-assisted app builder without giving up control over their data or environment.
