Load Balancing

Dedicated Workers' Load Balancing​

Your worker can be located in 4 different sites: San Francisco, New York, Amsterdam, or London. If you request to https://chrome.browserless.io, it will redirect to one of the 4 regions.

In order to improve the latency by having a worker located closer to your client, you'll want to use the load balancer closest to your machine to reduce the distance data from requests must travel. These are the load balancers available for you to point your traffic to:

  1. West load balancer (SFO): https://chrome-us-west.browserless.io
  2. East load balancer (NYC): https://chrome-us-east.browserless.io
  3. UK load balancer (LON): https://chrome-eu-uk.browserless.io
  4. AMS load balancer (AMS): https://chrome-eu-ams.browserless.io

Multiple Worker Load Balancing​

When you have multiple instances, it'll automatically load-balance amongst them by least connections. If you want to handle load-balancing on your end, you can get the endpoint for every individual worker by clicking on the URL in the "Address" Column in the Production Workers table available in your account dashboard.
