Flexible local app builder

Dyad is a local, open-source AI app builder for building apps on your own machine. It combines an AI-driven chat workflow with code you can inspect, approve, export, and run locally, so the app-building process stays under your control.

The product is designed for people who want flexibility rather than a managed platform. It supports multiple AI models, connects to tools such as Supabase, and includes deployment paths to GitHub and Vercel. The quickstart shows a simple flow: install Dyad, install Node.js, set up AI access, prompt the builder, approve the generated code, and run the app locally.

Core capabilities

Model flexibility

Build with OpenAI, Anthropic, Google Gemini, Ollama, LM Studio, and other models without being locked to one provider.

Local, owned code

Keep generated apps on your own machine and export clean, runnable code instead of working inside a closed system.

Supabase workflow

Connect Supabase accounts to add database, authentication, and server functions to full-stack apps.

Version comparison

Review generated changes with per-version diffs and inspect the files changed in each app version.

Built-in security reviews

Scan for critical security issues such as SQL injection, XSS, and auth misconfiguration before publishing.

Publishing and extensibility

Deploy to GitHub and Vercel in a few clicks, or bring your own cloud and use MCP servers or templates to extend the workflow.

Common ways people use Dyad

Start a new app from scratch
Use Dyad to scaffold a new web app from a chat prompt, then approve the generated code and run it locally on your own machine.
Build a full-stack app with backend services
Connect Supabase when you need database storage, authentication, or server functions in a full-stack app.
Inspect changes across versions
Review per-version diffs to understand what changed between app versions before you continue editing or revert work.
Check code before publishing
Run security reviews on generated code to catch issues like SQL injection, XSS, or auth misconfiguration earlier in the process.
Publish or hand off an app
Export or deploy the result to GitHub or Vercel when you want to move an app out of the local build environment.

Pros and Cons

Pros

Runs locally on the user's machine, which keeps app creation and generated code under user control.
Supports multiple model providers, including OpenAI, Anthropic, Google Gemini, Ollama, and LM Studio.
Exports clean code and allows import/export workflows, reducing lock-in.
Includes practical workflow support such as Supabase integration, security reviews, version diffs, and deployment to GitHub or Vercel.
Has a documented quickstart that walks through setup and first-app creation.

Cons

The collected pricing page URL returns a 404, so pricing details are only partially documented in the material provided.
Some documented capabilities, such as the desktop-app FAQ item, are not fully answered in the collected source text.

FAQ

Is Dyad free, and what does the paid plan add?

Yes. The home page says Dyad is free, downloadable for macOS and Windows, and requires no sign-up. The paid Pro plan adds exclusive Pro modes, 200 AI credits per month, and full Dyad Academy access.

What can you build with Dyad?

Dyad is built for creating AI apps locally, including full-stack apps that can connect to Supabase for database, auth, and server functions. The homepage and docs also show deployment to GitHub and Vercel.

How do you get started with Dyad?

The quickstart explains that after installing Dyad, you install Node.js, set up AI access through an API key such as Google Gemini, Anthropic Claude, or OpenAI, then type a prompt and approve the generated code before it runs locally.

Does Dyad run locally?

The quickstart says Dyad runs on your machine and the homepage describes it as local-first and open-source. It also notes a Windows-specific warning during installation that can be bypassed with 'More info' and 'Run anyway.'

Can you build desktop apps with Dyad?

The source materials mention app-building workflows, code export, version diffs, and deployment, but they do not claim native desktop-app output in the material provided. The FAQ item on desktop apps is present on the site, but the collected text does not include its answer, so that capability should not be assumed here.
