Trifle is an open-source time-series analytics library that stores pre-aggregated answers rather than raw events, offering a single-call API to track metrics with nested dimensions. The 'store answers, not events' approach reduces storage costs and query latency compared to event-based analytics pipelines, making it interesting for teams wanting lightweight product metrics without a full data warehouse.

Target audience: backend developers and product teams needing lightweight in-app analytics
