ArbiGap: Best Crypto Arbitrage Opportunities & Crypto Spread Broker Scanner

Live price comparison across exchange plateforms. Flags the tightest spread and biggest cross-exchange gaps in real time.

ArbiGap scans public market data across up to 29 major crypto exchanges in real time and surfaces the tightest spreads and biggest cross-exchange price gaps, all from a resizable Chrome side panel that stays open while you browse. No sign up needed. No API key. No trading permissions. Just live bid/ask data, organized. 🔍 WHAT ARBIGAP DOES __________ ArbiGap pulls live bid/ask prices for the same asset from every exchange you choose, lines them up side by side, and calculates the spread between the best buy and best sell price. In other words the exact number that matters when you're screening for a cross-exchange opportunity. Every price comes straight from each exchange. There's nothing to connect, authorize, or trust with your funds. 📊 SCANNER TAB __________ A live, auto-refreshing table of your customizable assets watchlist showing the best ask, best bid, and resulting spread across every exchange you've enabled. Rows are sorted by spread size so the biggest gaps float to the top, with a configurable highlight threshold to flag anything worth a closer look. Click any row to expand it and see 24h volume and top-of-book liquidity for both the buy and sell side, without cluttering the default view. 🔄 COMPARE TAB __________ Type any symbol and see every tracked exchange that lists it, side by side, with the cheapest buy and best sell venue instantly highlighted. Perfect for checking one asset in depth before you act. 🎯 FILTERS BUILT FOR FOCUS __________ Scan everything, or narrow it down exactly how you want with three independent filters: which base assets to watch, which quote currencies to allow (USDT, USD, USDC, EUR, GBP, BTC, ETH), and which exchanges to include. Each filter opens a searchable checklist with check-all/uncheck-all and a "show selected" toggle, so managing a custom setup never means scrolling through everything you don't want. 💧 LIQUIDITY & VOLUME AT A GLANCE __________ A quoted spread is only real if you can actually trade against it. Where the data is available, ArbiGap shows top-of-book liquidity and 24h volume for both legs of the trade, right alongside the price, so you can tell a genuinely capturable gap from a thin, illusory one. ⚖️ QUOTE-CURRENCY INTEGRITY __________ ArbiGap only ever compares venues quoting the same currency for a given asset. A USDT price is never silently measured against a USD price. Mixing the two makes ordinary currency drift look like a real spread. If you want to exclude a specific quote currency instead of comparing across all of them, the quote filter handles that too. ⚙️ CUSTOMIZABLE SETTINGS __________ Set your own refresh interval, choose your highlight threshold, and decide whether each asset shows only its single best exchange pairing or every valid cross-exchange combination. 📤 EXPORT & IMPORT YOUR SETUP __________ Save your entire filter configuration (assets, quote currencies, and exchanges) as a single JSON file, and load it back on another machine or after a fresh install in one click. 🔐 PRIVACY BY DESIGN __________ ArbiGap never asks for an account, an API key, or trading permissions on any exchange. It only ever reads public market data. There is nothing here that could touch your funds. ⚠️ IMPORTANT DISCLAIMER __________ The spread shown is gross (the raw gap between the best ask and best bid) and does not account for trading fees, withdrawal fees, network transfer time, or slippage from order size. Treat it as a screening tool to identify candidates worth investigating further, not as a guaranteed, executable profit figure. Analysis and setups shown in this extension are educational, not financial advice. 🚀 GET STARTED __________ Click the ArbiGap icon to open the side panel, let it fetch each exchange's data, and start scanning. No sign-up, no setup wizard, just live prices, right where you're already browsing.
