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.

Snyk

  • Free plan has strict test limits across all modules: Open Source (200), Code (100), Infrastructure as Code (300), Container (100) tests per month
  • Free and Team plans count only contributing developers making commits within 90 days; public contributions do not count
  • Enterprise plan requires custom pricing and sales contact
