Install the extension
Yahoo closed its Fantasy API to unapproved apps on 22 July 2026, so this site cannot ask Yahoo for your team directly. The extension reads it from the Yahoo pages you already visit, and hands it to this site.

Open your team on Yahoo, once
That is how we learn your roster. A summary strip appears above the table; the numbers show up here right after.
What it asks for, and why
- Your Yahoo Fantasy pages
- To read your roster, matchup and league categories. That is the only way left since the API closed.
- Notifications and alarms
- For the lineup and waiver reminders you set yourself. Off until you turn one on.
- Local storage
- To keep what it read on your own machine. You can clear it any time from the extension button.
It never adds, drops or trades. The only change it can make on Yahoo is starting your already-active players, and only when you click it yourself. Reading pages you have not opened is off until you allow it.
