Built for the Fan Who Wants to Know
HeadToHeadStats is the most comprehensive player comparison platform on the internet — 18,000+ athletes across the NFL, NBA, MLB, and NHL, powered by real data and AI analysis.
Our Mission
HeadToHeadStats was built on a simple belief: every sports debate deserves more than an opinion. Whether you're settling a bar argument about Tom Brady vs. Patrick Mahomes, deciding who to start in your fantasy lineup, or deep-diving into 20 years of career statistics — you deserve real numbers, real context, and a real verdict.
We combine official league statistics with Claude AI (built by Anthropic) to generate analysis that goes beyond raw numbers. Every head-to-head comparison includes career stats by season, positional context, head-to-head matchup records where applicable, and an AI-written breakdown that respects both players.
Our fantasy football tools go even further — pulling live season data from Sleeper, computing breakout scores from 3 years of PPR production, and generating personalized draft strategies for your specific league format.
What We Offer
Data & Accuracy
We source statistics from official league APIs and trusted third-party providers including Sleeper (fantasy stats), ESPN (career data), and NHL Stats API. Our database is maintained and updated regularly. AI analysis is generated fresh for each matchup and cached to ensure fast load times.
We do not guarantee 100% accuracy on all historical statistics — data sources occasionally differ on edge cases like late-career trades or mid-season transactions. If you spot an error, please contact us and we will investigate and correct it.
