Good question, I don't use any custom api servers for this. It queries the hacker news and reddit public api's directly from your browser, no other servers are contacted or information stored. It uses ajax to check if a post exists on one of these sites. If it does, then it finds the number of comments and link to the post. Have a try and Let me know what you think! Cheers
