Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Apache Druid

  • Open-source offering lacks high-availability, distributed architecture, and enterprise security features
  • Requires native integration with Apache Kafka or Amazon Kinesis for real-time ingestion; custom integrations need development
  • High-concurrency query support (hundreds of thousands QPS) requires significant cluster infrastructure investment

RescueTime

  • No free tier since 2023, making it costly for individual experimentation
  • Limited iOS support compared to competitors that offer full mobile app access
  • Requires integration via categories and rules rather than direct app detection on some platforms
