Best Free Odds Comparison Sites Compared

The short answer

All four sites compare odds for free, but they're built for different bettors.

• Oddschecker is best for UK recreational bettors who want the best price at UK bookmakers, especially on horse racing, shown in fractional odds.
• OddsPortal is best for odds history and archived results, with a huge range of leagues and in-play odds, but UK visitors only see soft bookmakers (plus Betfair Exchange), with no sharp bookmakers like Pinnacle.
• Oddspedia is a good all-rounder with live odds, tips and a set of free betting tools.
• OddsHub is best for value betting: it compares 490+ bookmakers against sharp prices like Pinnacle's, so you can see which prices are actually too big, not just which is highest. It also shows Pinnacle's no-vig odds, the "odds to beat", on every match.

We built OddsHub, so we're not neutral. Below, we've stuck to what each site actually shows, checked from the UK on 9 November 2026, so you can judge for yourself.

What makes a good odds comparison site?

Showing the highest price is the easy part. These are the things that separate the useful sites from the rest:

• Bookmaker coverage. More bookmakers means a better chance of finding the top price. What you see often depends on where you live, because many sites only show bookmakers licensed in your country.
• Sharp bookmakers. A site that includes sharp bookmakers like Pinnacle lets you compare prices with the most accurate odds in the market, not just with other soft bookmakers.
• How "value" is measured. Many sites flag value bets. The question is what they compare against: the market average, their own model, or a sharp bookmaker's price with the margin removed.
• Where dropping odds come from. A drop at a sharp bookmaker usually means informed money. A drop at soft bookmakers often just reflects what the public is backing.
• Odds history and closing odds. Seeing how a price moved, ideally on a chart rather than a list of numbers, and where it closed, lets you check whether your bets beat the market.
• How the site makes money. Most free comparison sites earn commission when you sign up to a bookmaker through them, so expect plenty of welcome offers, bookmaker adverts and pop-ups pushing you to sign up.

The comparison at a glance

Oddschecker

Oddschecker is the best-known odds comparison site in the UK. It compares 26 bookmakers on Premier League match odds and shows prices in fractional odds by default, which suits UK bettors used to high street prices. It's particularly strong on horse racing.

Its Market Movers page lists the biggest steamers and drifters, comparing the best original odds with the best current odds. Oddschecker describes these as moves "where user interest has forced the bookmakers to take action", so they mostly reflect what the public is backing rather than sharp money.

Through Oddschecker+, it also offers EV bets based on an AI model's probability, mostly on player props.

Best for: UK recreational bettors, horse racing, and finding the best price at mainstream UK bookmakers.

OddsPortal

OddsPortal has been comparing odds since 2008 and covers a huge range of sports and leagues, pre-match and in-play. Its standout feature is history: archived results and historical odds let you look back at how prices moved and where they closed.

It has free dropping odds, filtered by how many bookmakers have cut their price over the last 1, 12 or 24 hours, plus sure bets and value bets. Its value bets work by comparing a bookmaker's odds with the average odds of the same outcome. That finds prices above the market average, but an average of soft bookmakers isn't the same as the true price.

For UK visitors, OddsPortal listed 19 bookmakers when we checked, and Pinnacle wasn't one of them.

Best for: odds history, results archives and broad league coverage.

Oddspedia

Oddspedia combines odds comparison with live scores, tips and a set of free tools: surebets, dropping odds, value bets and betting calculators. It also runs tipster competitions and leaderboards. Across all countries it covers 183 bookmakers and keeps an archive of over 5 billion past odds, though, as with most comparison sites, you'll only see the bookmakers licensed where you live.

It's a solid all-round site, though its value bet page doesn't say which price it measures value against, which makes it harder to judge how reliable the picks are.

Best for: live odds, tips and an all-in-one free toolkit.

OddsHub

OddsHub compares odds from 490+ bookmakers, exchanges and prediction markets, including sharp bookmakers like Pinnacle, Sbobet and SingBet, the Betfair Exchange, and prediction markets like Polymarket and Kalshi. That's the main difference: instead of only showing you the highest price, it shows you how each price compares with the sharp market.

• Dropping odds are tracked at sharp bookmakers, so a drop usually means informed money, not public interest.
• Value bets are measured against Pinnacle's odds with the margin removed, the closest thing to a true price.
• Free Pinnacle closing odds and odds movement charts let you check whether your bets beat the closing line.
• No bookmaker sign-up offers. OddsHub isn't paid by bookmakers to send you to them. It makes money from the optional paid Terminal instead, so there are no bookmaker adverts or pop-ups getting in the way of the odds.

The trade-off: OddsHub doesn't cover horse racing tips or news. The odds comparison is free, with no delay once you create a free account. The Terminal is a separate paid upgrade, with a free plan on a 15-minute delay.

Best for: value betting, beating the closing line, and comparing soft bookmakers with sharp prices.

Which odds comparison site should you use?

• You bet for fun at UK bookmakers: Oddschecker.
• You want odds history, closing odds, results or in-play prices: OddsPortal or OddsHub.
• You want tips and tools in one place: Oddspedia.
• You want to find bets that are actually priced too high: OddsHub.

There's nothing stopping you using more than one. Many bettors use a UK site for the bookmakers they hold accounts with, and OddsHub to check those prices against the sharp market.
