In-Thread Replies
Stay in the thread
Inline reply and quote selection let you respond in place instead of jumping across pages.
Why Install Orange Juice?
If you already use Hacker News every day, Orange Juice gives you better ways to read and respond without changing the site you know. The value is simple: fewer extra clicks, clearer unread state, and faster replies when a thread is worth your time.
Unread Tracking
Keep context between visits
Unread comment highlighting and hide-read controls make it obvious what is new and what you already covered.
Favorites
Save what matters
Use keyboard commands to favorite stories and comments while reading so you can quickly find them again later.
Following
Track people, not just threads
Follow HN users, open a combined activity feed, and keep it ordered the way you read.
Keyboard Flow
Move faster without the mouse
Keyboard navigation and shortcuts help you scan stories, open threads, and act on content without breaking reading flow.
Readability
Make long threads easier to parse
Dark mode, better code styling, and cleaner comment structure reduce friction when threads get deep or technical.
Feature Screenshots
This is not a complete list of features, but it shows what we’re actively building and already delivering. Even this subset should make a strong case for installing Orange Juice.
Inline Reply + Quote Selection
Reply directly inside comment threads and quote selected text with one action.
Unread Comment Highlighting
Quickly spot what changed since your last visit without rescanning the entire thread.
Hover User Details
Hover usernames to quickly preview profile details and context without leaving the thread.
Following Feed
Follow users from anywhere on HN and open a dedicated feed of their recent comments and submissions. Reorder users by dragging, collapse sections you do not want open by default, and refresh one person at a time without reloading everything else.
Small follow buttons appear next to usernames across Hacker News.
The /following page keeps the normal HN look
instead of inventing a separate UI.
Recent fetched activity is cached locally to keep the page fast, with per-user refresh controls when you want a fresh pull.
Hide Read Stories
Clear out items you already opened and focus your attention on new stories.
Keyboard Navigation
Move through stories and comments faster with keyboard shortcuts, so you can browse without constant mouse movement.
Mermaid Diagram Rendering
Render Mermaid code blocks into readable diagrams directly in threads.
GitHub Emoji Shortcodes
Render comment shortcodes like :heart: and
:+1:
as emoji while leaving code examples untouched.
And too many other features to list.
Safe, Open, and Engineered
Orange Juice is designed to be trustworthy by default:
transparent code, clear licensing, and disciplined development.
Fully open source
The full source code is public under the GPLv3 license, so anyone can inspect how it works, verify behavior, and contribute improvements.
AI-assisted, not AI-slop
AI is used as a pair programmer to speed up implementation and review, but architecture and final decisions are human.
Tested, not vibe coded
The extension has extensive unit test coverage, quality checks, and automation through CI/CD. This project is intentionally not vibe coded.
