Does it do the things that Drupal Views does? For example aggregating and joining nodes? I have views that do that and also some that export Json files. I couldn’t transfer a Drupal site to WordPress because I needed that functionality.
Sorry, I’m not clear what you mean by “aggregating and joining nodes”. Are you referring to View’s relationships? I’ve not explored Query Wrangler extensively, my use case is very simple. My sense is that there are probably a few things it can’t do that Views does natively. I’ve not talked with the developer, but reading the support forum, he seems quite responsive.
These were all different modules but I couldn’t find anything that would do things like that and I imagine it would be too big a task for one developer to undertake.
