How to take a screenshot of a remote site?

Question

PHP

Are there any solutions that would be suitable for shared hosting, i.e. without installing additional libraries or programs on the server?
PHP has an imagegrabscreen function , but it takes a screenshot of the executable site. Maybe there are some libraries that emulate a browser (curl is not suitable here, I think), allowing you to work in symbiosis with this function?
If it is impossible or difficult to implement the task without additional libraries or programs, then what would be the best solution?
UPD: There is no question about third-party APIs due to the GDPR, it is better not to use them in this project.

Answer 1

Search in Google: javascript site screenshot and render a picture on the user's computer, then upload it to yourself. The problem is the low quality of these screenshots.
