What Dyad is

Dyad is a local-first open source AI application builder. The site emphasises that it is flexible, local and open source with zero lock-in, and it supports connecting different AI models and MCP tools.

It also includes a built-in security review and publishing support.

What you can do with it

• Build an app on your own machine
• Choose which model does the work
• Connect MCP tools
• Publish when the app is ready

Who it is for

• Developers who want local control
• Independent builders
• Open source enthusiasts

What to watch out for

• Complex production structure, team collaboration conventions and long-term maintenance still need planning
• Local execution is private but your hardware sets the limits
• The built-in security review is a filter, not an audit
• Confirm current model and platform support
