Pick QuestDB when

  • SQL-first analytics teams
  • Self-hosting infrastructure shops

When QuestDB is not a fit

  • General-purpose app data that isn't time-series
  • Teams wanting a fully managed cloud database
  • Non-technical teams with no ops capacity
  • Small projects . Postgres or a simple store suffices
