Sportsbooks We Compare
Full game lines and player props, ranked side by side so you see who's actually paying more.
Prediction Markets
Real-money exchanges, included in the exact same price comparison as every sportsbook above.
DFS Pick'em Apps
Real, direct PrizePicks Standard/Goblin/Demon lines on every prop we cover, then every other book's price checked against that same real line to find you the best number.
OddsGap VerifiedWe don't ask you to trust a screenshot. Every logged pick is chained into a tamper-evident hash ledger the moment it's logged and locked again once it's graded. Edit or delete one after the fact and the record shows it. Results are measured against closing line value (CLV), the same metric sharp bettors and sportsbooks use internally, because it can't be faked on a small sample.
Most picks arrive automatically via GapSync's live book sync or Scan Slip's bet-slip photo upload, not hand-typed in after the result's already known. Full CLV coverage across moneylines, spreads, totals, and player props, every sport we carry.

Line Scanner
Every sportsbook price for a game, ranked against the Sharp Price or Market Consensus, so you see which book is actually paying more than the bet is worth.
Gamecast
Live play-by-play for every sport we cover, with real ball/shot trajectory replays (not just a static chart), drive charts, win-probability swings, and full box scores. Browse any live game right now, or go back and replay real historical games for years back, not just today's slate.
Player Props & Alt Lines
Every player prop cross-checked the same way, plus a dedicated Alt Lines view pulling every alternate number a book offers into one list. Live for MLB, WNBA, and NFL today, expanding to the rest of the slate as each season opens.
Player & Team Profiles
A real bettor-style profile for every player and team: league rank, recent performance, radar-chart archetype breakdown, and a full season game log, not just a splits table.
Prop History
Full distribution, trend, and decision hierarchy on any prop line, not just a hit-rate number.
Line Movement
Full pregame-through-live odds history, so you can see exactly when and how a line actually moved.
DFS Pick'em Coverage
Real, direct PrizePicks Standard/Goblin/Demon lines, plus Underdog's own real per-leg prices, with every other book matched against those same real lines, never an estimated number.
CLV Grader & Pick Tracker
Log every bet, get it auto-graded against the closing line, the one number that tells you if you're actually beating the market.
GapSync
Link a book account once and every bet syncs automatically going forward, no manual logging. Kalshi and Polymarket sync through their own official APIs; PrizePicks sync is experimental since PrizePicks has no public API to use instead.
Scan Slip
Upload a screenshot of your bet slip and it's read and logged automatically, no typing in odds and stakes by hand.
Performance Dashboard
Your real record over time: ROI, units, and CLV trends by day, week, sport, and book.
Bettor Profile
Your own spider-web radar chart, real betting archetypes, and a breakdown of your genuine strengths and weaknesses.
OddsGap Verified
Every logged pick chained into a tamper-evident hash ledger the moment it's logged, locked again once graded.
Season Recap & Integrity Report
A real shareable card for your season: audit score, chain-verified pick count, and an honest trail of every correction or deletion, not just a stats screenshot.
Reputation Score
CLV quality, sample size, and consistency rolled into one real skill score, separate from raw win rate.
Public Leaderboard & Hall of Fame
See real, verified track records, sortable by raw ROI% or by Reputation Score.
Bankroll & Kelly Sizing
Kelly-based stake sizing and exposure caps, so bet sizing stays disciplined instead of gut-feel.
Confidence Score & Matchup Web
A single synthesized confidence read on a game, plus a web visualizing every real factor feeding it.
Market Pressure
Real public betting % (bets vs. money) and flags for when the money backs a different side than the ticket count.
Parlay Builder
Log real parlays leg by leg, auto-graded against the closing line, with correlation warnings when legs on your slip tend to move together.
Betting Tools
Bet Grader, Hedge Calculator, Odds Converter, Kelly Calculator, Vig Calculator, and Live Line Shopper: quick calculators for the math you'd otherwise do by hand.
Pick Pairs
Surfaces sides that keep winning together on the same slate in your own pick history, an honest pattern read, not a claimed statistical correlation.
