What are JS\PHP\NODEJS standalone libraries for 2020 for automatic background removal?

Question

PHP

Perhaps someone has met or used libraries to automatically remove the background on the image, i.e. the script finds the main object and removes everything unnecessary.
I would like to know what actual and effective stand-alone (not online services with API and their plugins) libraries in JS or PHP or NODEJS are available today in 2020, and which one is better at this task. Unless, of course, there are any ready-made solutions at all ... :)
