HN Roast Feed ranks live Hacker News discussions by their heat index — a ratio of comments to upvotes that surfaces the most controversial and heated threads. Instead of sorting by points or time, HN Roast Feed highlights where the real debates are happening. Stories with 400 comments but only 45 upvotes score far higher than a 500-point post with civil agreement. It color-codes threads from Mild to Inferno so you can jump straight to the action.
