About YordleDiff

A free companion site for ranked players who want an edge before lock-in.

YordleDiff bundles the parts of the game that are decided before minions spawn into six tools: the tier list, the team builder, a win-condition analyzer, the duo synergy tool, the build optimizer, and the jungle path planner.

Everything is computed in your browser from current-patch ranked data. No account, no install, no Riot integration required.

What is YordleDiff?

YordleDiff is an independent League of Legends tools site. It bundles a champion tier list with win/pick/ban rates, a champ-select coach that calculates bans and comp-aware builds for your whole team, a win-condition analyzer that classifies both teams into one of eight archetypes, a synergy tool that surfaces the teammates who measurably raise your champion's win rate, an item-build optimizer with matchup-adaptive swaps, and a per-jungler clear-route planner.

Is YordleDiff free to use?

Yes. Every tool on the site is currently free to use, with no account or install needed. Open any tool and use it immediately. Nothing you enter is uploaded — calculations run on your device.

What rank do the stats come from?

All win rates, pick rates, and build data are sourced from ranked Emerald+ games on the current patch (16.11). Pair-synergy data requires at least 100 sampled games per pair for inclusion, and comp-aware build picks use the Wilson lower bound rather than raw win rate to avoid recommending high-variance items.

Is YordleDiff affiliated with Riot Games?

No. YordleDiff is an independent fan project. It is not endorsed by Riot Games and does not reflect the views of Riot Games or anyone officially involved in producing or managing League of Legends. League of Legends and Riot Games are trademarks or registered trademarks of Riot Games, Inc.
