What type of software is Xrumer, scrapebox? ~ client side application?

Just wondering what type of software is Xrumer, scrapebox, etc? Are those client side applications since they have to access a server to valide the username/password?

Thanks

Anyone know? Thanks

These kinda applications are client side. They don't access the server. They communicate with server through the post request. Servers can understand only these get and post messages. So, User name and password are added as fields and sent to server. Validation is done in server and response is received by the same tool, decrypted and wanted operations are performed.

Client side refers to the process being performed by the user's computer/browser/application.

Server side refers to the task being performed on the server end (e.g. automatically updating database information).

All of these apps, are desktop apps, thus are client side, with some server interaction.

they are thin client multi-tier applications (or at least scrapebox is for sure as I used to use it), scrapebox has a GUI program that runs on the user's machine and then this communicates with an API on their centralized server somewhere (most likely using POST requests, as someone already said), most of the functionality is in this core centralized app which they did so that the software can't be pirated, since the user can't have direct access to this
