Description
Get an instant vibe of who's commenting. View their top subreddits in a glance. A browser extension for Chrome and Firefox that gives you an instant vibe of who's commenting. It displays coloured split-pill badges next to Reddit usernames showing their most active subreddits — visible at a glance without leaving the page. Works on both WWW.REDDIT.COM and OLD.REDDIT.COM. --- HOW IT WORKS When an author link scrolls into view the extension queries the Arctic Shift API ([https://github.com/ArthurHeitmann/arctic_shift](https://github.com/ArthurHeitmann/arctic_shift)) to retrieve that user's top subreddits by activity. A huge thank-you to Arthur Heitmann and the Arctic Shift project for making this data openly accessible — this extension would not be possible without it. NOTE ON ACTIVITY COUNTS: the count shown on each pill represents COMBINED POSTS AND COMMENTS the user has made in that subreddit during the configured time period, not posts-only. --- FEATURES * SPLIT-PILL BADGES — each badge shows [subreddit | count] with distinct background colours for the subreddit name and the activity count. * ALL SUBREDDITS — not limited to any specific community; shows whichever subreddits a user is most active in. * SORTED BY ACTIVITY — pills are ordered highest-count first. * CLICK TO SEARCH — clicking a pill opens an author-scoped subreddit search (/r/SUBREDDIT/search?q=author:USER) in a new tab. * VISIBILITY DETECTION — only processes links currently in the viewport; new content loaded by infinite scroll is picked up automatically. * DE-DUPLICATION — already-labelled links are skipped; concurrent requests for the same username are coalesced into one. * RATE-LIMIT HANDLING — respects x-ratelimit-* headers; shows a clickable retry badge when paused. * 1-WEEK CACHE (CONFIGURABLE) — user data is cached in chrome.storage.local and only re-fetched after expiry. * OPTIONS PAGE — configure API parameters, pill colours, cache duration, and pause/resume the extension without reloading the page. --- OPTIONS Open the extension's options page (via the browser toolbar or chrome://extensions → Details → Extension options) to customise: SETTING: NUMBER OF SUBREDDITS DEFAULT: 10 DESCRIPTION: How many top subreddits to show per user (1–100).
