Everything they charge for? Free here.
Yahoo locks median scoring behind a paywall. ESPN pushes gambling ads. We believe core fantasy tools should be free for every manager.

Managers don't go back
Real scenarios our substitution engine was built for.
My starting back tore up his knee in the first quarter. I subbed in my bench guy and still won by 9. On ESPN I'd have been dead in the water.

3-year league commissioner
The projections page actually shows the floor, ceiling and boom rate — not just one made-up number. It's the only tool I trust for tough start/sit calls.
Priya S.
Two-time league champ
I cancelled my paid fantasy add-ons. Everything I was paying for is here for free, and the live subs are genuinely something no one else does.

We got tired of losing to bad luck
Every manager knows the feeling: your stud goes down early, and there is nothing you can do but watch a zero sit in your lineup. The big platforms have never fixed it — because a broken Sunday keeps you refreshing their app.
So we built the fix ourselves: live in-game substitutions with frozen-point scoring, powered entirely by real NFL data, and we made every tool free — forever. No paywalls, no gambling ads, no catch.

Frequently asked questions
What are live in-game substitutions?
They let you swap a player out of your lineup during an in-progress NFL game — for example when a starter gets injured or underperforms. Points already earned are frozen and kept; the incoming player scores from the moment of the swap.
How does scoring work when I substitute?
A lineup slot total = Frozen Points (everything the players you subbed out already banked) + the New Player's Points (everything the current player earns after entering the slot). You never lose points already scored.
Is FantasyFootballSubs free?
Yes. Create an account, build your roster, and start making real-time substitutions during live NFL games at no cost.
Do you use real NFL data?
Yes — live scores, rosters, fantasy points, injury status, and standings are all powered by real NFL data.
