Overview

Connect your ESPN Fantasy league to League Blitz in one click. Syncs your league data automatically.

League Blitz brings your Yahoo, Sleeper, and ESPN fantasy leagues into one dashboard, with live scores, matchups, rosters, power rankings, and AI matchup analysis. This extension exists for one thing: connecting your private ESPN leagues. ESPN doesn't offer a public login for third-party apps, so for private leagues this extension reads your ESPN session from your own browser and securely syncs your league data to your League Blitz account. No copying cookies by hand, and no ESPN password is ever asked for or seen. - One-click connect for private ESPN leagues - Auto-detects the leagues you're in - Keeps your league data refreshed - Your credentials are encrypted and used only to fetch your own leagues Public ESPN leagues and Yahoo/Sleeper leagues don't need this extension. You can connect those directly at leagueblitz.app. Not affiliated with ESPN, Yahoo, or Sleeper
