Which Browsermob proxy replacement can I choose?

Question

proxy

The point is this. This tool is good for almost everyone, but there are nuances that fundamentally do not suit me in its work. They can be discussed here , but what interests me now is: what tool can I choose to replace this tool? The requirements are the following:

• Ability to work through API
  
• The ability to work not just as a proxy, but as a proxy manager, that is, the ability to create separately living proxies, with all their individual settings, and manage them via API
  
• Correctly work with proxy chains, that is, be able to not only independently proxy traffic to network resources, but also proxy it to other proxies.
  
• Living either as a separate standalone application, or as a php project (this is of course unlikely), or as a project that has a PHP SDK.
  
• Collection of statistics in har or some other format, as complete as possible.
  

What can you advise?
