Repolode describes open-source projects and does not give investment advice. Trading and investing can lose money: assess the risk yourself and follow the laws where you live before using this project.

What is it?

OpenTerminal is a dark, widget-based trading dashboard that runs locally in the browser. It combines several free public market data endpoints, such as Nasdaq, Yahoo Finance, TradingView, CoinGecko, Binance and FRED, so users can watch quotes, charts, news, screeners and macro indicators without paying for a data subscription.

The workspace uses draggable and resizable panels saved in local storage, a Cmd+K command palette for searching symbols, and a charting view with several candle and line styles, eight timeframes and common indicators such as SMA, EMA, VWAP, Bollinger Bands, RSI and MACD. Each data source has a fallback chain, and results are cached so a single provider outage does not blank the interface.

The backend is an Express API with SQLite for portfolio tracking, and the frontend is built with Next.js and React. An optional AI assistant uses Anthropic's Claude when an API key is set. The data is delayed or indicative and is intended for personal and educational use rather than trading decisions.
