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.

Socket

  • Team plan requires minimum 5-developer commitment, expensive for small teams
  • Business plan $50/dev/month becomes costly for teams exceeding 20 members
  • Enterprise pricing requires custom consultation with no transparent pricing
  • Free plan limited to individual developers without team collaboration
  • Reachability analysis improvement (90% false positive reduction) only on Enterprise
