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. Works with your Claude Code, Codex or OpenCode account.

Requirements

On your own server

npx toyon deploy fly up my-toyon

Keeps running when your laptop is closed, on Fly or behind Tailscale. Your code and keys never reach a Toyon server.

Setup

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.
