The short version

  • Only QuestDB has a free tier, so it costs nothing to try first.
  • Each has a real cost: EnergyCAP priced per meter per year, so cost scales with how many utility connection points exist rather than with users or sites; QuestDB open-source edition lacks high-availability, distributed architecture, and enterprise security features
  • They diverge on capability: EnergyCAP covers Utility bill management, QuestDB covers High Throughput Ingestion.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

EnergyCAP

  • Priced per meter per year, so cost scales with how many utility connection points exist rather than with users or sites
  • No figure is published at any level, and every package is quoted by sales
  • Emissions, interval data, bill capture and bill pay are separately priced add ons rather than part of the core platform

QuestDB

  • Open-source edition lacks high-availability, distributed architecture, and enterprise security features
  • Enterprise edition pricing not published; requires contacting sales for custom quote
  • Ingestion limit of 20M rows/sec platform-dependent; may not scale to extreme throughput requirements
