Market-Data Head-to-Head
Alpha Vantage remains the only viable option between these two platforms. While IEX Cloud historically offered institutional-grade datasets with real-time streaming at competitive credit-based pricing, it permanently shut down on August 31, 2024. Alpha Vantage fills this gap with a freemium model: 25 requests/day on the free tier, scaling to unlimited access with premium subscriptions. Both platforms historically emphasized developer-friendly REST APIs with strong documentation, but only Alpha Vantage operates today.
The critical differentiator is operational status. Alpha Vantage's 50+ pre-computed technical indicators and AI/LLM integration support appeal to algorithmic traders and developers building automated systems. IEX Cloud's strength was transparent credit-based pricing and institutional-grade coverage—advantages that ceased mattering when the service was discontinued.
Traders deciding today have one choice: Alpha Vantage. For prototyping and backtesting with modest request volumes, the free tier works; serious algorithmic traders need premium access for real-time data and unrestricted queries. IEX Cloud's retirement eliminates the decision entirely—no developer would choose a defunct service.
