+
+For platforms that support live desktop/browser streaming, here is how the underlying technologies compare:
+
+| Dimension | WebRTC (Neko) | VNC (noVNC) | CDP Screencast | WebSocket + JPEG |
+|-----------|:---:|:---:|:---:|:---:|
+| Typical latency | 50-150ms | 100-500ms | 200-1000ms | 150-400ms |
+| Frame rate | 30-60 fps | 10-30 fps | 1-15 fps | 5-20 fps |
+| Video quality | High | Medium | Low-Medium | Medium |
+| Audio support | Yes | No | No | No |
+| Interactive input | Full | Full | Limited | Limited |
+| Bandwidth (adaptive) | Yes | No | No | No |
+| Used by | Sandbox Agent | E2B, Gitpod | Browserbase | Various |
+
+Sandbox Agent uses [Neko](https://github.com/m1k1o/neko) (WebRTC) for streaming, which provides the lowest latency and best interactivity of any approach. The same stream serves both the full desktop and browser automation modes.
