Have a look at Dynamic-Web-TWAIN

"a cross-platform scanning SDK designed for web document management applications. With just a few lines of JavaScript code, you can develop robust web applications to scan documents, edit images and save them to file systems".

This is the only one I have come across. You can also search for more on github.

  • I am also searching for a good / affordably price solution. The above option is very expensive for me: +- 3000$ per server. Commented Jan 20, 2023 at 17:09

I've found someone suggesting this...: Yes, there is an application that enables scanning on the remote machine. When someone opens the browser a connection between the web browser and that local machine application is established...

Please try this: ScanAppForWeb

  • At the moment, this looks spammy. You should really declare if you have an affiliation to the site. Commented Jul 16, 2023 at 13:39
