OpenChart

OpenChart brings AI agents into every step of your investment journey: statistical and technical analysis with code and charts, real-time responses to market events with alerts, opportunity discovery through agentic research, and more.

OpenChart is not built to monetize software, but to explore a future where humans and agents manage assets together. If you believe in this future and want to join forces, we want to talk to you.

Quick start

Download Desktop for macOS (Apple Silicon), open the disk image, and install OpenChart.

To run Desktop from source, install Node.js 24, npm 11.11.1, Bun 1.4.2, and Just, then run:

git clone https://github.com/longsurf-ai/openchart.git
cd openchart
just install --frozen-lockfile
just desktop

just install also initializes and builds Tea, a programming language built for analyzing market, by the same team. Follow the setup guide for your first chart and alert, or the development guide for building and packaging the app.

Desktop is free. Bring your own AI agents and market data through TradingView, Yahoo Finance, Binance or local datasets. Those providers keep their own terms and costs. OpenChart no longer offers its own market-data service.
