I can't tell if you can create custom hooks (similar to zapier's zaps) without signing up.
Also we recently introduced source settings by which you can tailor your notifications for example follow a certain product on PH and so on.
We do support Twitter, tumbler, HN, PH, reddit and much more.
It's 100% free
cheers ^^
EDIT: Just realized that HN is going to be sensitive to this comment due to the "middlebrow criticism" issue. I have absolutely no problem with Twilio's blog post or this project. Hacky fixes have their place -- just know what you're doing and don't abandon hope of getting good infrastructure some day.
E.g. I created a pipe today to give me an RSS feed of HN submissions about Haskell.
For example: http://hnapp.com/?q=haskell%20type%3Astory%20score%3E20
Twilio consistently provides excellent documentation and developer support, whereas Google's results on that front are very mixed (varies widely by product).
Twilio is a whole extra level of cruft. Any machine can send an email, so unless you want a voice call to tell you someone mentioned you on HN it makes absolutely no sense.
