Counterplay

Counterplay is a free desktop app for League of Legends on Windows 10 and 11. It runs next to the League client during champ select and suggests which champion to pick for your role.

Each suggestion is scored from ranked matches of the current patch: the champion's win rate, the matchup against your lane opponent, matchups against the rest of the enemy team and synergy with your allies. Small samples are smoothed, so a handful of lucky games can't push a pick to the top. The list updates every time someone hovers or locks a champion.

For the chosen champion, Counterplay shows items, runes, summoner spells and skill order. One click puts the rune page into the League client.

Also included:

• ban suggestions for your role;
• champion pools per role;
• your win rate per champion and a rank chart for the last 30 or 90 days;
• your team's composition style and damage mix;
• interface in 15 languages.

Counterplay reads champ select through the League client's local API (LCU). It works only during the draft: it never reads game memory and by default hides to the system tray when the match starts. It never asks for your Riot account login and shows no ads.

Counterplay isn't endorsed by Riot Games.
