Frequently asked questions
DonBest is one of the longest-running sportsbook line services in the industry, with consumer odds screens (basic, premium, pro tiers based on real-time access) and a B2B data feed sold to sportsbooks and pro syndicates. ThunderBet is a modern bettor analytics platform that grades every odd against Pinnacle no-vig fair price for real EV, composes alert rules across 7 signal sources, aggregates prediction-market trades on Kalshi and Polymarket via Whale Watch, runs Trap Detector for sharp-vs-soft sportsbook divergence, ships an AI Betting Assistant, and runs Betting Bots. DonBest is the line data; ThunderBet is the analytics layer on top.
DonBest's consumer platform offers tiered access (Basic with a delay, Premium with full sportsbooks and customization, Pro with real-time data); current dollar amounts aren't published on a public pricing page and should be verified inside the product. The DonBest B2B data feed for sportsbooks and pro operations runs from approximately $100 per month at the low end to $10,000+ per month for high-volume customers, with custom quotes. ThunderBet is currently in Beta with 50% off all plans: Starter is $19.99 per month and Premium is $49.99 per month.
DonBest historically targets professional bettors, sportsbooks, and B2B data customers rather than mass-market retail. The interface emphasizes line data, opening odds, and historical movement over modern tooling like graded EV screens, custom alerts, or AI research. ThunderBet is built for retail bettors who want professional-grade analytics without a B2B data subscription.
DonBest publicly markets line aggregation, opening odds, line movement, and historical data rather than per-odd EV grading against Pinnacle no-vig fair price. ThunderBet grades every odd in real time against Pinnacle no-vig and surfaces +EV bets in the +EV Bet Finder, with the same engine used for arbitrage detection.
DonBest publicly markets coverage of traditional sportsbook lines and historical odds; Kalshi and Polymarket prediction markets are not listed in publicly available consumer materials. ThunderBet's Whale Watch surfaces large trades on Kalshi and Polymarket alongside traditional sportsbook odds, with alert support.
DonBest publicly markets line movement and historical data tools rather than a configurable alert system with custom rules and multi-channel delivery. ThunderBet ships push, email, SMS, Discord, and Telegram alerts with cross-tool rule composition across 7 signal sources, a 7-day backtest preview, customizable payload, quiet hours, and rate limits.
If you need DonBest's deep historical line data or its B2B feed for an outside model, the two are complementary. Use DonBest for raw sportsbook line data and historical movement; use ThunderBet for graded EV analysis, signal-based alerts, prediction-market action, and AI-assisted research. For most retail bettors, ThunderBet alone covers the workflow.
