Where each one falls short

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

CodeSandbox

  • Detailed paid plan pricing was not published on the accessible pages, making cost comparison difficult.
  • Focus has shifted toward programmatic sandbox infrastructure, which may be less approachable for casual users just wanting a quick online editor.
  • Public sandboxes are visible to others by default, which is not ideal for proprietary code.

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.
