Gekko is currently the most popular open source crypto trading bot with over 6,000 stars on Github. Right out of the box, users are given a web GUI that allows them to import historical market data, backtest their strategies, and run them live on their favorite exchange.

We recommend you run Gekko on your local machine to test and develop your crypto trading strategies. Once you have your strategy ready to go live, install it on a VPS like [Vultr](https://www.vultr.com/?ref=7393934) to guarantee 24/7 uptime and low latency trades.
