Learn how Fora Soft built Fox Runner — a real-time stock market news platform generating ~$5M annual revenue with 6,000+ traders, from Electron desktop to React Native mobile.
Fox Runner's MVP with real-time news aggregation, user accounts, and subscription management took about 3–4 months. The full platform — including sentiment analysis, 15+ keyword filters, insider tracking, Grafana analytics, and the React Native mobile app (launched January 2026) — was delivered over 8–10 months. Fora Soft's Agentic Engineering approach can accelerate similar projects 2–10×.
Fox Runner is built on AWS with RabbitMQ message queues, MongoDB for data storage, and Express/TypeScript backend — designed for 6,000+ concurrent traders. Load balancing and auto-scaling ensure the platform handles traffic spikes during market volatility without degradation.
Fox Runner uses RSS-Parser and Puppeteer scrapers to aggregate press releases and market data from multiple sources in real time. WebSocket connections push updates to all connected clients instantly — traders see breaking news, keyword alerts, and market changes the moment they happen.
Fully customizable. Fox Runner's sentiment analysis engine scores market news automatically, while 15+ keyword filter settings let traders create personalized color-coded alerts. Insider ownership tracking and deal flow identification highlight actionable trading opportunities in real time.
Fox Runner runs on Electron for desktop (Windows, macOS) and React Native for mobile (iOS and Android) — all sharing the same Express/TypeScript backend. The mobile app launched January 2026 with custom filters, real-time push notifications, and full market analytics, synced seamlessly with the desktop experience.
The platform uses SSL encryption, OAuth2 authentication, and secure payment processing for subscription management (monthly, semi-annual, annual plans with 1-month free trial). All sensitive financial data is handled through certified payment providers with PCI-compliant infrastructure.
