NeetCode Versus Companion Autor: Rakesh Reddy

Unofficial companion for NeetCode Versus. Not affiliated with or endorsed by NeetCode.

Queue with one key, get pulled back the moment an opponent is found, see your odds before you write a line, and watch your rank move when it's over.

Never miss the start
- A chime, a desktop notification, and the match tab brought to the front the instant a match is found, even if you're on another NeetCode page or the browser is minimised.
- Clicking the notification takes you straight into the match.

Queue without going back to the lobby
- Press Alt+M anywhere in Firefox to start a search. It never navigates away from a match in progress or a problem you're working on.
- Optional auto-queue: a new search a few seconds after each result, cancellable.

Know your opponent, automatically
- A scouting card reads both players from the match header. No typing names.
- Win chance estimated from both ratings, with a verdict from "Long shot" to "Heavy favorite".
- Rating, win rate, ranked games and problems solved, side by side.
- The card collapses once you start coding, and you can drag it anywhere.

See your rank move
- After each match: the result, your rating change, a bar filling toward the next tier, and a promotion or demotion banner.
- The new rating is confirmed by re-reading your public profile, so it matches what NeetCode shows.

Your dashboard
- Tier emblem, rating, global rank, rated matches left today, and today's record.
- Recent matches, a rating chart, win rate by difficulty, best streak, rivals, and 14 achievements to unlock.

Privacy
- No analytics, no tracking, no third-party servers.
- The only thing sent anywhere is a public profile lookup (a Versus name) to neetcode.io, the same request the NeetCode website makes.
- Your settings and match history are stored only in this browser. You can copy or erase them from Settings.

Permissions
- neetcode.io: reads the Versus pages and looks up profiles. It runs on no other site and never reads your code or sign-in.
- Notifications: the match-found alert.
- Tabs: finding your NeetCode tabs and bringing the match tab to the front.
- Storage: saving your settings and record.

Requires Firefox 140 or newer. Shortcuts can be changed in about:addons under Manage Extension Shortcuts.
