Dyad

Dyad is a free, local, open-source AI app builder that runs on your computer and lets users build apps using their own data and AI models. It emphasizes ownership of code and data, with no dependence on a cloud provider. The tool targets developers and non-developers who want to create web apps from ideas without committing to a cloud platform. The reference describes Dyad as an alternative to other builders and highlights its local-first nature.

Dyad operates by keeping app code in a folder on the user’s machine, enabling work with the chosen AI model and local resources. It supports importing repositories, editing with VS Code, and exporting clean code. The workflow is designed to avoid vendor lock-in and cloud reliance, offering visibility into prompts and diffs and enabling offline work with local models.

Dyad’s main capabilities include full-stack database and authentication integration with sources like Supabase or Neon, built-in security scans that check for bugs and misconfigurations, and one-click deployment to GitHub and Vercel. It also offers model flexibility, letting users bring their own API keys, switch between providers, and run even offline models while retaining full source code ownership.

Dyad presents plans and platform details: it provides downloadable desktop builds for macOS, Windows, and Linux, and emphasizes local, open-source operation with no cloud lock-in. It offers a Free tier and paid options (Pro and Max) with different AI credit allowances and features, and supports integration points like MCP plugins and various AI providers.
