Verdict

Massive targets developers and quants who need granular tick-level market data without usage caps, positioning itself against incumbents like Polygon.io and Alpaca. Its free instant-access tier lowers the barrier to entry for prototyping. The main tradeoff is limited brand recognition and unclear enterprise SLA details compared to more established financial data providers.
