I have code that monitors Hacker News comments for mentions of various things (including cloudflare, my username). It runs once a minute and uses https://hn.algolia.com/ to find new comments. I actually saw this was on Hacker New via Twitter.
Genuine question; I’ve got a static IP (v4) to my only server that I run at home. Are there any real benefits I gain to using tools like this one (or Tailscale et al)?
