Is there a library instead of selenium?

Question

C++ / C#

The question is, for example, you need to register on the site (example), but you don’t really want to do it through the web driver. I saw that people do it on QT, and even multi-threaded (with a web driver you can’t run 50 threads). So the question is, is there any library that works in a similar way? Yes, I know that you can see what data is being sent and send it all POST, but this does not work on JS sites where data is generated in the process of working with it (for example, when clicking on an input).

Answer 1

99% of registrars/parsers/posters can be made without using a browser emulator using, for example, the wonderful https://github.com/csharp-leaf/Leaf.xNet
If you really need an emulator, in 99% of cases you will not need 50 threads ( Do you seriously need 100,000 accounts per day? With 50 threads, the performance will be about the same).
Yes, and with Selenium Chrome 50 threads on a more or less modern machine, it will not be a problem to run.

Answer 2

NWJS is great for things like this. From third-party applications, it steers perfectly through web sockets.
