Ask for changes to your web app & try them as they happen.

Every chat gets its own running copy with a live preview.

The Toyon window. The list of chats down the left, the chat beside it with the agent's reply, and the app it is working on, a plant shop, filling the rest of the window.

On your machine

cd your-project
npx toyon

macOS and Linux. Needs Node 18 or newer and an account for the agent you pick; the install doc has the rest.

On your own server

Keep it running when your laptop is closed: deploy it to your own Fly account, or run it on a box of your own behind Tailscale and open it from your phone. Your code and keys never pass through a Toyon server.

How to set it up

Ask, and watch it change

Say what you want, or point at it on the page. The app updates as the agent works; steer it, or fix the small thing yourself.
