dsh-sidebar-cdp-browser

Want to watch and drive a Chromium running on a server or in a container straight from the DSH sidebar—without installing VNC clients on every workstation? This plugin projects the external browser into the DSH sidebar as a live JPEG pixel stream on a canvas. Open the tab and the remote page appears; click the canvas and you can issue clicks, drags, wheel events, keyboard input, and navigations, all with zero CDP passthrough.

Security is the core design: the client never learns the CDP address, every command must pass a zod strict discriminated-union allow-list, and no {method, params}-shaped CDP passthrough exists of any kind. Interaction sits behind a two-level gate—a global master switch plus a per-view checkbox—defaulting to observe-only. Only with both engaged can the view accept control input, and the host enforces the ticket mode so even a forged client cannot emit a single control command.

Typical use cases include remote or headless Chromium visualization, real-time supervision of an AI-driven browser session with the ability to take over at any moment, projecting a permission-scoped demo browser to colleagues with zero client installs, and multi-observer monitoring of a single browser session. Frame rate, JPEG quality, and maximum resolution are all adjustable in the web settings panel; on save the host disconnects existing views with code 1012 and they reconnect automatically with the new parameters in effect.
