Playground

The Playground is a developer tool for connecting to a live session and exercising it interactively — without writing any frontend code.

What it does

The Playground opens a live connection to one of your deployed app functions and gives you widgets to drive it: send control-doc updates, push input media such as a webcam feed, and watch the session's output streams in real time. It's the fastest way to confirm a freshly deployed app actually serves a session.

When to use it

• Smoke-test a new deploy before wiring up a real frontend.
• Reproduce a session bug interactively while watching Logs and the session's Events.
• Demo an app to a teammate without standing up a UI.
