The short version

  • Each has a real cost: Directus free permissive use of the self hosted product is limited to organisations under $5M annual revenue with fewer than 50 employees, so crossing either threshold turns a free dependency into a paid licence; QuestDB open-source edition lacks high-availability, distributed architecture, and enterprise security features
  • They diverge on capability: Directus covers REST API, 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.

Directus

  • Free permissive use of the self hosted product is limited to organisations under $5M annual revenue with fewer than 50 employees, so crossing either threshold turns a free dependency into a paid licence
  • The free Core tier is a hard limit of 3 seats, 25 collections and 5 flows
  • The Team plan is $499 a month billed annually, or $599 monthly, with extra seats at $50 each
  • Team caps collections at 50, expandable to 100, and flows at 20

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
