What it does
Compare live odds across 19 sportsbooks and 4 exchanges (Kalshi, Polymarket, ProphetX, Novig), pregame and live in-play, best price flagged on every line. Line shop game lines and props, grade PrizePicks, Underdog, Betr and Pick6 on the DFS board, plus an 8-mode hedge finder, middle finder, bet tracker with CLV, 11 calculators, and a Discord bot. One-tap betslip deep links, light or dark. Nothing paywalled; a free email unlocks the 60-second live board. Math, not picks. Built solo in Michigan.
Side-by-side moneyline, spread, and total prices across every major US sportsbook. Find the best line before you bet.
Same bet, better price. We do not sell picks. We do the arithmetic that tells you which book is paying the most for the exact bet you were going to make anyway. Live odds from every major sportsbook and prediction market, side by side, refreshed through the day so the number you see is the number that is up. Pinnacle and the prediction markets set the fair price. We strip out the built-in margin (the vig) to see what each side is really worth, with no juice baked in. When one book drifts off that fair number, that difference is value you can capture. We show you the best price and exactly how much better it is than the next book. Math, not picks.

- UBUsing bots and maths to beat the sportsbooks2023 · whop.com · ▲13
I have recently developed a bot capable of simultaneously scanning over 140+ sportsbooks around the globe. It analyzes millions of odds in real time and uses this data to find overpriced odds. The logic behind it is straightforward: it uses odds from all sportsbooks to calculate the probabilities of an event occurring. Then, with simple maths it determines if the expected value is positive, meaning the potential payout exceeds the risk. Unfortunately, sportsbooks limit your accounts once they realize that you are profitable and not a losing customer. So I have already been limited at more…

I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

OpenSEO▲928Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
