How it works
Short on purpose. A game nobody can follow is not a game.
- 1
Two products enter
You get a matchup: two products, each with a logo, an eight-word pitch, a screenshot and a link. Tap the one you'd ship. That is the whole game, and it takes about a second.
- 2
Always the same category
An AI tool never fights a marketing tool. Cross-category votes measure which category you like rather than which product is better, so every matchup is drawn from one category only.
- 3
The board resets at midnight UTC
A forever leaderboard is a graveyard of old winners. The daily board scores duels won minus duels lost from zero each midnight UTC; yesterday's #1 becomes Product of the Day, and the weekly board keeps the longer story.

Ratings, not raw likes
All-time strength is an Elo rating: beating a strong product moves you far, beating a weak one barely at all. Matchmaking pairs similar ratings, so most fights are close — and a close fight is the only kind whose result means anything.

Every matchup keeps a page
Each fight lives at a permanent address like /duel/notion-vs-obsidian, with the running tally and the argument underneath it.
- 6
The weekly boss fight
The week's top two are pinned as the featured duel. Beat the boss in the crowd's eyes and next week you are the boss.
- 7
One verdict per matchup per person
Your browser gets exactly one call on each matchup, forever. You cannot judge a duel your own product is in, and nothing moves your product up except strangers picking it.

You judge before you are judged
Submitting is free and needs no account — a URL, a name, a category, a pitch, at most 3 a day. Your product waits until you have called 10 duels yourself, then goes live with its first 50 fights guaranteed.

Accounts are for talking
Sign in with X, GitHub or Google to comment, post in the forum and get a profile. Voting and submitting never need one — a login wall on the main loop is how sites like this stay empty.

Free stays free
Judging costs nothing and always will. There are no paid votes and no paid ranks; if money ever shows up it stands next to the fight, never inside it.
