It bothers me that I see an increasing number of apps that run a local web server. I've got half a dozen apps, mostly development tools like pgAdmin, that force me to run the app and then access the UI through a browser. How many such apps am I running that I don't know about? And how many of them are exposing my system to malicious web sites, or to curious people in my office on the same subnet? I wish I knew.
