Where each one falls short

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

Pusher

  • The free Sandbox plan is capped at 100 concurrent connections, which is quickly outgrown by production apps.
  • Pricing jumps sharply between tiers (e.g. $49 to $99 to $299), leaving few options for teams with moderate but growing usage.
  • Priority support with faster response times costs an additional $3,000/month on top of plan pricing.

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.
