Fantrax is the deep-league platform, and it's the widest sport range Roster Locker supports — NFL, NBA, MLB, NHL and soccer. Connect with your Secret ID and let the AI read your real rosters.
Roster Locker connects Fantrax through its sanctioned fxea API using your personal user Secret ID — never your password.
No other platform Roster Locker supports spans this many sports in one login. Fantrax connects NFL, NBA, MLB, NHL and soccer — ideal for deep-league and dynasty players who run rosters across several sports.
Fantrax mints a new league ID each season (like Sleeper's dynasty rollover); reconnecting a new season's league is quick.
Roster Locker is free to start. Paid plans (Pro $7.99, All-Pro $14.99, Hall of Fame $22.99 per month) add more AI credits — but live-draft help is always free and unmetered, on every plan, on every platform.
