FBref & Understat alternative
A free home for xG — with the predictions FBref never had.
When FBref lost its advanced data in January 2026, the free xG people relied on lost its home. xG Lab keeps expected goals free and open — then goes further, turning it into win-probability replays, match predictions and season projections you can actually check.

What you get
Frequently asked
- Is there a free alternative to FBref for xG data?
- Yes. xG Lab publishes free expected goals (xG) for the Premier League and La Liga, alongside win-probability replays, match predictions and season projections. The core site is free; an optional Pro tier unlocks the deepest player and projection tools.
- What happened to FBref's advanced stats and xG?
- In January 2026 FBref's data partner (Opta / Stats Perform) ended the feed that supplied its advanced metrics, including expected goals. FBref remains an excellent free reference for basic stats, but its xG and other advanced data were removed with no announced replacement.
- How is xG Lab different from Understat?
- Understat is a great free xG database, but it stops at the raw numbers. xG Lab adds an out-of-sample win-probability model you can replay minute by minute, pre-match win-probability predictions, Monte Carlo season projections, and — unusually — an honest scorecard of how the model performs against the closing market consensus.
- Does xG Lab claim to beat the market consensus?
- No. We publish the comparison openly: the market consensus is still slightly sharper than our model. The point of xG Lab is a fully transparent, open-logic model that gets close to the consensus — a model with nothing hidden, not a service promising certainty.
