Questions
Do I need the browser extension?
For live Underdog drafts, yes — a lightweight extension mirrors your picks onto the board in real time. It installs in about a minute (step-by-step guide) while our Chrome & Edge store listings are in review. Running a home or off-platform draft needs no extension at all — just open the board and draft each pick yourself.
Is it safe? Will it touch my Underdog account?
The extension only reads the draft you're already looking at in your own browser. It never makes picks for you, never signs into your account, and never sees your password. Your draft data syncs to your BestBallTracker account and nowhere else. BestBallTracker is an independent tool — not affiliated with, endorsed by, or sponsored by Underdog Fantasy.
Which contests does it work with?
Every Underdog Fantasy Football Best Ball contest type — from 2-, 3-, 4-, 6- and 12-person sit-and-gos to large-field tournaments and satellites, across scoring formats. It reads each draft's own settings, so the board always matches your contest.
What does it cost?
Your first draft is completely free — no credit card. Pro is $4.99/month (or $39/year with a 7-day free trial) and unlocks unlimited drafts plus exposure tracking across every draft, all season.
Is the extension in the Chrome / Edge stores yet?
The store listings are in review. You don't have to wait — install it now in about a minute with our quick setup guide, and it'll switch to one-click auto-updates once the listings go live.
