Wallabag the server is ok, not amazing at rendering webpages to be readable, and article thumbnail view needs work.
The browser plugins are the nightmare (Chrome comes to mind) You need to manually generate an API key and configure it in the browser. The process is very confusing, and too much work to configure on multiple machines with multiple browsers. The plug-ins are written by different developers, all open source as a hobby, so I while I think the effort is admirable and I hope it continues, it is still a beta experience.
