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

npx toyon ~/projects/app

Local by default, with the agent you already use: Claude Code, Codex or OpenCode.

What you need

On your own server

npx toyon deploy fly up my-toyon

Runs on with your laptop closed, on Fly or a box behind Tailscale. 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.
