Frequently asked questions from the Hyperbeam community
Streaming
To ensure optimal performance of Hyperbeam virtual computers, it is recommended that your users meet the following bandwidth requirements. Even though users who have less bandwidth available can still stream virtual computers, the image quality or framerate may be suboptimal.
| Resolution | Framerate | Bandwidth Required |
| ---------- | --------- | ------------------ |
| 720p | 24fps | 5mbps |
| 720p | 30fps | 6.3mbps |
| 900p | 24fps | 7.8mbps |
| 900p | 30fps | 9.8mbps |
| 1080p | 24fps | 11.3mbps |
| 1080p | 30fps | 14.1mbps |
Enabling sharp mode triples these bandwidth requirements.
Monitoring
Yes, you can detect when a user changes the virtual browser URL by using Hyperbeam’s tab event listener API available in our Web SDK. We do not currently provide a way to directly detect this action server-side.
Proxies
Not at the moment. Hyperbeam uses a variety of server providers which makes it difficult to whitelist Hyperbeam servers based on IP. You can use username/password authentication to ensure traffic originates from Hyperbeam.
{
"http_proxy": {
"pac": "function FindProxyForURL(url, host) {return {'PROXY 255.255.255.255:12345'}",
"username": "<username>",
"password": "<password>"
}
}

Caveats:
- Only HTTP traffic is sent through the proxy server. WebRTC traffic is excluded. Hence, there is no functional difference between the use of SOCKS, HTTP or HTTPS protocol on the proxy server.
- Authentication is not supported for SOCKS protocol. This is due to it not being implemented by Chrome.
- Due to these reasons, we recommend the usage of HTTPS to authenticate and secure communication between Hyperbeam and the proxy server: HTTPS Proxy Scheme.
Troubleshooting
Requests to the Hyperbeam API should not be made from the client as doing so exposes your API key to users which can easily be abused. Instead, API requests should only be made from a backend such as Vercel, Netlify or Cloudflare.
