K is a family of (very customizable) very low latency market-making trading bots with a fully featured web interface. It can place and cancel orders on one of the several compatible exchanges in less than a few milliseconds per order on a decent machine. If you don't want to configure or hardcode your own trading strategies in your own machine, you can run strategies from someone else at kryll.io (or at any other trading community out there). Our bots run on unix-like systems. Persistence is achieved through a built-in server-less SQLite C++ interface. Data transfers are directly done from your machine to the exchange using the latest CURL and OpenSSL versions. Installation in a dedicated Debian, Raspberry, Red Hat, CentOS or macOS instance without Docker is recommended. The web UI is compatible with most web browsers/resolutions, but Brave or Firefox at 1600px are recommended. Doesn't require configuration of any web server (unless installed behind your own reverse proxy).
