In simple English
OpenAlgo is a self-hosted control center for algorithmic trading. You can build trading strategies, test them with fake money, and run them live through thirty-six supported brokers. It gives you a visual editor, a Python code runner, and an AI chat assistant in one place. You run it on your own server, so your keys and trading data stay private. It is free to use under an open-source licence, but you need your own broker account and capital to trade.
What it is
A Python and React application that provides a unified REST API, real-time WebSocket data streaming, and multiple execution surfaces for financial trading. It handles order management, strategy hosting, risk controls, and market analytics without locking you into a single broker.
What it is good for
Traders who want to run automated strategies across different brokerages without paying for expensive commercial trading software or exposing their credentials to third-party cloud services.
- Connects to thirty-six different brokers through a single normalized API contract.
- Includes a visual drag-and-drop strategy builder alongside an in-browser Python runner.
- Runs entirely on your own hardware with encrypted token storage and zero data sharing.
- Requires comfort with the command line and basic server configuration to install and maintain.
- Consumes modest memory to run the Flask backend, React frontend, and SQLite databases.
- Uses the AGPL licence, which has strict rules if you modify and host the software as a public service.
