Duels
by LightFreecs
Duels adds ranked player-versus-player matches to Minecraft, with ELO climb leaderboards across several kits, for players who want to compete on Fabric.
What it does
Players queue for ranked PvP matches, and each player carries one skill figure. That figure combines OpenSkill Bayesian skill estimation with an ELO reward system, and it drives matchmaking. Smart placement pairs opponents of similar strength, so strong players face each other and weaker players can climb by winning rather than grinding at the bottom.
Matches take place in several kits, from weapon-focused setups to team and survival-style formats. Global and per-kit leaderboards track each player's climb. Team modes allow 2v2 and 3v3 matches with friends through parties and a social menu.
The mod needs Fabric API and runs on the client only, so players install it themselves and a server does not need it. Duels is published for Fabric 1.21.11 only, and the code is licensed under All rights reserved, so it is not open source.

Who it’s for: Players who want ranked PvP on Fabric 1.21.11 and groups who play team matches together. Server owners do not need to install it, because only the client runs it.
How it compares
Duels is a client-side only Fabric mod for 1.21.11, published under All rights reserved. MCRanked is also client-side only and built for 1.21.11 under All rights reserved, so the two share the same install side and version. EloTiers Ranked PVP covers 1.21 – 1.21.11 on Fabric and needs the client while the server may skip it, so it suits a wider version span.
