Some years ago, I discovered a bot called Little Birdie to watch HN comments for keywords and post a link to Slack. Unfortunately, it has disappeared and I've found myself missing this.

So this bot is a re-implementation of it, but now also supporting Discord.

It's very easy to use: 1. install the bot on your workspace/guild 2. /keywords add rust,hn,foobar (for Discord) ; @newsbutler add rust,hn,foobar (for Slack) 3. done

For technical stuff : it is implemented in Crystal + Postgres (hosted on Render+Neon). I will certainly opensource it when I clean the repo of all production secret.

I'm the only user currently, so it is certainly missing some basic optimizations to support HN crowd size. Please don't hug it to death.
