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.

Endor Labs

  • Pricing requires contacting sales, no transparent rates
  • Developer tier lacks UI and historical scan data
  • Free tier limited to local scanning only
  • Seat-based model may become expensive for large teams
