- Description: Which browsers and computers can play OpenBeam Cloud, what your network needs, and how to get a smooth stream.

OpenBeam Cloud runs the simulation on our servers and streams the picture to your browser. Your computer only decodes video, so it doesn't need a powerful GPU. It does need a browser and network that can carry the stream.

## Browser

- **Use Chrome or Edge on a Mac or PC.** OpenBeam Cloud streams over WebTransport and decodes with WebCodecs, which these browsers support.
- **Safari, and every browser on iPhone and iPad, can't play yet.** Their WebTransport stalls the stream after a few seconds. You can still sign in and manage your mods and recordings there.
- Other browsers without WebTransport can't play either. The Play tab tells you if yours is one of them.

## Network

- **A wired connection helps.** Wi-Fi works, but a cable gives steadier frame times.
- **Bandwidth.** The stream is 1080p at 60 fps and 20 Mbps by default. In the player you can choose 5 to 50 Mbps, or **Auto bitrate**. See [Use the player toolbar](https://openbeam.world/docs/player-toolbar/).
- **UDP.** The stream uses UDP. Networks that block UDP traffic, such as some company or campus firewalls, can stop it from connecting.

Before a session starts, OpenBeam Cloud checks your connection (*Checking your connection…*).

## For a smooth stream

- Close other tabs or apps that use a lot of bandwidth.
- If the picture stutters, lower the bitrate in the player toolbar.
- Use **Stats** in the toolbar to see the frame rate and bitrate, and **Latency test** to measure input delay.
- Go fullscreen and use **Capture mouse** for driving and camera control.
