In plain words
This open-source Chrome extension adds a notification inbox widget to Hacker News, alerting users when someone replies to their threads or comments with an unread bubble indicator. It includes optional email notifications with batching support and makes navigating to new replies straightforward. The extension requires only a public Hacker News username and polls the HN API once per minute to check for updates, regardless of user count.

No cookies, nothing! * This extension works by polling HN API every minute from the backend server to check for new updates. (No matter how many people use this extension, the server calls HN API only once every minute) == Why? == Isn't it much better when there is a way to know that I have an unseen comment? Otherwise, I have to keep refreshing HN to know if someone replied. I'd love to hear your thoughts on this. How do you currently check for new replies to your comments?

Heya HN, I've been working on a reddit-like platform as my primary side project for the last few years. Doing a (very) soft launch today, mainly because I want to use it to encourage discussion of alternatives. How non.io works: 1. Free to browse, paid to interact. 2. Minimum subscription is $2 (though you can choose more). I take $1 to run the servers, everything left gets split evenly between everything you upvote that month. It's a simple model, but I hope it's a better one than the freemium model we've been relying on for the last few years. Fundamentally I feel like any ad-supported…
