Dyad
A local, open-source AI app builder that creates owned web-app code using cloud or local models.
About Dyad
Dyad is a desktop AI app builder for creating web applications through a chat-based workflow. You describe an idea, inspect and approve the generated code, and run the project locally with a live preview. It supports cloud models from OpenAI, Google, and Anthropic, along with local options such as Ollama and LM Studio, so teams can choose their model setup instead of being tied to one provider. Generated code stays accessible and can be imported or exported, while Supabase support covers database, authentication, and server functions. Deployment can flow through GitHub and Vercel or another cloud. Dyad is open source and runs on the user’s machine, but setup still requires Node.js and AI access. Model API usage may carry separate provider costs, and some agent capabilities, including conversation-history search, are associated with Pro.
Best for
Best use cases
Turn an early product idea into a runnable local prototype, then inspect and approve the generated changes before continuing.
Import an existing app, ask for targeted changes in chat, and keep the resulting code available for further development outside Dyad.
Build a full-stack project with Supabase, then deploy through GitHub and Vercel or move the code to another cloud.
Compare before choosing
Unlike hosted builders that keep projects inside a proprietary platform, Dyad runs locally and lets users import or export their code.
Its model flexibility suits buyers who want OpenAI, Google, Anthropic, Ollama, or LM Studio rather than a single bundled provider.
The free desktop application lowers software entry cost, but external model APIs can add separate usage charges and Pro features require a subscription.
Features
Prompt-to-app building
Describe a web app in chat, review the generated code, approve it, and run the result locally with an in-app preview.
Full-stack app setup
Connect Supabase to add database, authentication, and server-function support while keeping the generated project code accessible.
Flexible deployment
Move a finished app to GitHub and Vercel in a few clicks, or take the owned code to another cloud and deployment workflow.
Pros
- The free, open-source desktop app keeps generated code accessible and supports import and export without platform lock-in.
- Support for cloud and local AI models gives teams flexibility over provider choice, privacy posture, and model-related cost.
- Supabase, GitHub, and Vercel workflows connect prompt-based building to familiar full-stack and deployment tools.
Cons
- Initial setup requires a Dyad installation, Node.js, and configured AI access before the first app can be generated.
- Using paid cloud-model APIs may create costs separate from Dyad, and actual charges depend on the selected provider.
- Some advanced agent capabilities, including conversation-history search, are limited to the Pro subscription tier.
