Pros & Cons
Pros
Supports over 50 cryptocurrency exchanges and 800+ currencies, enabling broad arbitrage detection as stated in the README's feature list.
Uses WebSocket integration to push live price discrepancies to a web interface, allowing users to monitor opportunities without manual refreshes.
Licensed under GPL v3, it provides a self-hostable, customizable alternative to proprietary tools, aligning with its democratization philosophy.
Users can add, remove, or disable specific markets and coins via the settings.js file, offering control over data sources as detailed in the README.
Cons
The maintainer is focusing on a private trading bot, leaving the public version with unfinished roadmap features and slower bug fixes, as noted in the README notice.
Adding new exchanges requires editing the settings.js file directly, which is cumbersome and less user-friendly compared to a graphical interface or API.
It only identifies arbitrage opportunities without acting on them, limiting utility for automated trading; the bot is planned for v2.0.0 but not yet implemented.
Requires Node.js ^V8.0.0, an older version that may cause compatibility issues with modern systems and lacks updates for newer Node.js releases.
