GitHub - fanjin-z/RedHN: A Reddit-style extension for Hac...
fanjinz · 2026-06-21 · via Hacker News: Show HN

A browser extension that makes Hacker News feel more familiar, readable, and interactive while keeping the official site, links, and account actions intact.

Motivation

RedHN brings a Reddit-style UX to Hacker News: card-based stories, clearer discussion threads, familiar actions, theme controls, and easier navigation, all while staying on HN. It is built for readers who love HN's content but prefer the comfort and flow of a more modern social-news interface.

Demo

30-second RedHN demo

Features

Card-based story feed

Stories become scannable cards with HN metadata, voting, links, comments, hide, and viewed states.

Sticky navigation and search

A sticky top bar, search, sidebar, and quick links make HN feeds easier to move through.

Visual comment threading

Thread guides, collapse controls, reply counts, inline replies, and reveal-more states make discussions easier to follow.

Hacker News actions still work

Voting, hiding, favoriting, replying, login, signup, submit, account, and logout actions still use HN's own links and forms.

Reading preferences and local state

Theme controls, viewed-story styling, read state, and mute filters let readers tune the interface locally.

Profile pages with more context

Profiles show karma, join date, about text, activity, submissions, comments, favorites, upvotes, and account controls.

A friendlier submit flow

Submit modes separate Hacker News, Ask HN, and Show HN posts with clearer URL, title, body, and rule feedback.

Classic fallback and isolated styling

The popup toggle restores classic HN immediately, while Shadow DOM keeps RedHN styling isolated.

Privacy

RedHN stores settings and read state locally in browser extension storage. It does not add analytics, tracking, ads, remote code, or a RedHN-operated backend.

RedHN runs on supported news.ycombinator.com pages and requests public metadata from the official read-only Hacker News Firebase API at https://hacker-news.firebaseio.com/.
