  • No built-in support for multi-tenancy
  • Limited transaction support compared to traditional databases

StackBlitz

  • Specific Teams and Enterprise pricing figures are not published; visitors must request a quote or infer from the pricing calculator.
  • Browser-based execution via WebContainers has limits on which native/binary dependencies can run compared to a real server-backed environment.
  • Heavy or resource-intensive workloads may be constrained by the end user's own browser and machine resources.
