Summary
Eight odds comparison sites for NFL line shopping, ranked on books covered, free tools and price, plus the math on why a better number matters.
Key takeaways
Best free screen: BettingPros lists NFL odds from the major sportsbooks and from prediction markets, including Novig, Kalshi, ProphetX and Polymarket, on one page at no cost.
Free grids: Covers, which now runs Odds Shark’s odds pages, and VegasInsider show the opening line and a consensus number next to eight or nine sportsbooks without a paid plan.
Paid tools: Action Network PRO costs $24.99 a month, Pikkit Pro $29.99 a month and Unabated starts at $99 a month; OddsJam’s app plans run from $19.99 to $499.99 a month.
The math: over 100 bets of $100 at a 50% win rate, taking -105 instead of -110 saves $216.45.
Prediction markets: Covers, VegasInsider and SportsbookReview list only sportsbooks, so bettors who use them convert prediction-market prices by hand. A pre-game straight trade on Novig carries no fee, which makes its contract price the whole cost.
The best odds comparison sites for NFL line shopping
Line shopping means checking the same bet at several books and taking the best number. An odds comparison site puts those numbers on one screen. On the afternoon of October 12, 2026, Covers had the Bills’ moneyline against the Rams at +145 at four books and +154 at FanDuel.
The ranking below weighs how many sportsbooks and prediction markets each site compares, what the free tier includes, the NFL tools on offer (opening lines, line history, consensus and alerts) and what the paid tier costs. Prices are from each vendor’s own pricing page or app listing in October 2026.

Covers: best free NFL odds grid
Action Network: best app and line alerts
Unabated: best for a sharp benchmark price
VegasInsider: best for the Las Vegas consensus line
SportsbookReview: best for odds history and betting splits

Why line shopping matters: the math on a better number
At -110 a bettor risks $110 to win $100, so a $100 bet wins $90.91. At -105 the same $100 wins $95.24. That’s $4.33 per winning bet, and it changes the break-even win rate from 52.38% at -110 to 51.22% at -105. The point spread page covers how those prices are set.
Run it over 100 bets of $100 each with 50 wins and 50 losses. At -110 the wins pay $4,545.45 against $5,000 in losses, and you’re down $454.55. At -105 the wins pay $4,761.90, and you’re down $238.10. The picks and results are identical, so the whole $216.45 gap comes from the price.
A half point does its work on the games that land exactly on the number. Suppose three of those 100 bets were on a +3 underdog that lost by exactly three. At +3 each one’s a push and you get the stake back. At +3.5 each one wins, worth $95.24 at -105, or $285.71 for the three. On a moneyline the gap is plain dollars: $100 on the Bills at +154 pays $9 more than at +145. The moneyline guide shows the payout math for any price.
Prediction market prices are often missing from odds screens
Prediction markets quote NFL games as contract prices from 1 to 99 cents instead of American odds, and Covers, VegasInsider and SportsbookReview list only sportsbooks. BettingPros and Unabated show several prediction markets, and Action Network shows Kalshi. Everywhere else, you’re comparing by hand.
A contract under 50 cents converts to plus odds as (1 minus price) divided by price, times 100, so 40 cents is +150. A contract over 50 cents converts to minus odds as price divided by (1 minus price), times 100, so 60 cents is -150. A Bills contract at 39 cents works out to about +156, which would beat FanDuel’s +154 in the example above.
Fees change what a converted price costs. Novig doesn’t charge either side a fee on a pre-game straight trade, so its contract price is the whole cost of a pre-game side, total or moneyline. Kalshi and Polymarket charge takers a fee and ProphetX takes a cut of net winnings, so a converted price from those platforms costs a little more than it looks. The prediction markets vs. sportsbooks guide compares the fee schedules in full.
How to choose an odds comparison site
Most bettors need one free screen and, at most, one paid tool. These four things decide which.
Coverage: A screen is only useful if it lists the books you hold accounts with, and the prediction markets if you trade on them.
Opening line and history: A number means more when you can see where it opened and how it moved.
Alerts: Paid alerts earn their price for bettors who wait on a target number; weekend bettors won’t miss them.
Price: Covers, VegasInsider, SportsbookReview and BettingPros are free for odds, and the paid tools charge for analysis on top.
Odds comparison sites FAQ
What is the best free odds comparison site for the NFL?
BettingPros, because its free NFL screen lists the major sportsbooks and prediction markets such as Novig and Kalshi together. Covers and VegasInsider are the best free grids for sportsbooks alone.
Do odds comparison sites include prediction markets?
Some do. BettingPros shows Novig, Kalshi, ProphetX and Polymarket, Unabated shows several on its odds screen, and Action Network shows Kalshi. Covers, VegasInsider and SportsbookReview don’t list prediction markets.
Is line shopping worth it for a casual bettor?
Yes, if you hold more than one account. Taking -105 instead of -110 is worth $4.33 on every $100 winner, which adds up to $216.45 over 100 bets at a 50% win rate.
Do I need a paid odds tool?
You don’t need one to compare prices. The paid tiers sell analysis on top: line alerts, a fair-value line, +EV and arbitrage finders, or closing line value tracking.
Which odds comparison site has the best app?
Action Network, for its line alerts and Kalshi column. BettingPros, Covers, VegasInsider and Pikkit also have iPhone and Android apps.
Where can I see this week’s NFL lines in one place?
The weekly NFL odds page lists spreads, totals and moneylines for every game on the card. The best NFL betting sites list ranks where to place the bet once you’ve found the number.
