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

ChartMogul

  • The free tier stops at $10K MRR, so it lapses precisely as a company starts to matter
  • Starter is capped at 3 team members and a single billing system connection
  • Two-way CRM sync and warehouse integration require the Pro tier
  • Pricing scales with your ARR rather than with usage, so the bill rises as the business grows
  • Enterprise starts at $19,900 a year and is required above $10M ARR
