When you start a dev server, OpenChamber can open it right inside the app instead of a separate browser tab — so you can see your site next to the chat and point at elements to ask about them.
Open the browser panel from the globe button in the app header. If a dev server is already running, it is listed there and one click opens it — OpenChamber finds it by looking at what is actually listening on your machine, so it works no matter how you started it.
When OpenChamber runs on another machine, its dev server is on *that* machine — `localhost` on your laptop is somewhere else entirely. The desktop app handles this for you: it opens a local port that carries the connection through to the remote dev server, so the page loads normally, with working hot reload and developer tools. You keep typing the address you expect; the plumbing stays out of your way.
