Are the two module the same in functionality or there is an advantage  
for each use?

If my main purpose is to extract from an external web server, which  
one should I use?

Or is it an overkill to install both module?

IA’s WebDev module is about exposing _Ignition’s_ web server to other tools, primarily by allowing you to code arbitrary endpoints with custom Python handlers for different HTTP verbs.

Sepasoft’s Web Services module does that itself, _and_ has tools to connect to other web services to better retrieve data.

For your purposes, I think Sepasoft’s module is worth considering, and the Webdev module is probably not necessary.

Great. Thanks for clarification!
