Hummingbot

Hummingbot is an open-source framework that helps you create and deploy high-frequency crypto trading bots. Originally developed by CoinAlpha, it has grown into one of the most active open-source trading bot communities, specializing in market making, arbitrage, and liquidity provision across both centralized and decentralized exchanges.

Unlike general-purpose trading bots, Hummingbot is architected for professional market makers and algorithmic traders. It provides standardized connectors for 30+ exchanges (both CEX and DEX), a strategy template system for building custom algorithms, and built-in scripts for common strategies like pure market making, cross-exchange market making, and arbitrage.

Hummingbot ships with a command-line interface and can be deployed via Docker. Strategies are written in Python with Cython optimizations for performance-critical paths, making it capable of handling high-frequency order book updates and execution. The bot supports both spot and perpetual markets, and its DEX connectors enable automated market making on Ethereum, Binance Smart Chain, and other EVM-compatible chains.

Compared to cloud-based alternatives like 3Commas or Cryptohopper, Hummingbot is fully self-hosted and open-source under the Apache 2.0 license, giving you complete transparency and control over your trading strategies and API keys.

Key features include:

• 30+ exchange connectors (CEX and DEX)
• Pure market making and arbitrage strategies
• Custom strategy development in Python
• Docker deployment support
• Real-time order book and trade data feeds
• Paper trading mode for strategy testing
• Active developer community and extensive documentation
