What the Free Scanner does
Free The BJF Free Crypto Arbitrage Scanner monitors price discrepancies across 30+ cryptocurrency exchanges in real time and surfaces opportunities where the same asset trades at different prices on different venues. It calculates approximate spreads, logs historical opportunities, and lets you filter by exchange and pair — but it does not execute trades. Use it to learn arbitrage patterns, validate that arbitrage spreads exist on your account size, and decide whether to upgrade to the automated VIP Crypto Arbitrage Bot.
Real-time price comparison across 30+ venues
Persistent opportunity database for backtesting
Per-pair, per-exchange, and spread-threshold filters
Direct download — no account, no credit card
Supported exchanges (30+)
The Free Scanner monitors spot prices across the following 30 cryptocurrency exchanges. Tier-1 venues (gold border) provide the deepest liquidity and most reliable price discovery; mid-tier venues are valuable for catching dislocations on lower-volume pairs.
Tier-1 venues are highlighted with a gold border. The paid VIP Crypto Bot extends coverage to 50+ venues, including futures and perpetual markets.
How to download and install
Installation takes about 3 minutes. The Scanner runs as a standalone Windows desktop application — no server setup, no API keys required.
Click the download button on this page. Windows will deliver BJF-Free-Crypto-Scanner-Setup.exe (~14 MB).
Right-click the .exe and choose Run as administrator. Accept the EULA and select an install location (default C:\Program Files\BJF\CryptoScanner).
Open from the Start menu. On first run, choose which exchanges to monitor (default: all Tier-1 venues) and set a minimum spread threshold (suggested: 0.20% to filter noise).
The main view shows opportunities sorted by spread. Click any row to see the exchange-pair detail and the historical log for that pair.
When a spread looks attractive, place trades manually on each exchange. The Free Scanner does not execute — it identifies. For automation, see VIP Crypto Arbitrage Bot.

Limitations of the free version
The Free Scanner is intentionally scoped — it identifies opportunities but does not act on them. We list the limitations explicitly so you can decide whether the free tool fits your workflow or whether the paid bot is the right next step.
- It does not place trades — it only identifies opportunities. All execution is manual.
- It does not calculate exchange-specific fees in detail — shown spreads are gross estimates; your actual net depends on your specific fee tier on each venue.
- It supports spot only — no futures or perpetual coverage. Futures-spot basis trading and perp-perp basis arbitrage are paid-only.
- Some exchanges may rate-limit the scanner during high-volume periods, causing brief gaps in the feed.
- No support SLA — this is a free tool. Questions are answered through community channels (forum, Telegram), not direct ticket support.
Upgrade to VIP Crypto Arbitrage Bot — $600 (50% off, regular $1,200). One-leg + hedge strategies, 50+ exchanges including futures, direct BJF support.
