  • 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.

SonarQube

  • Advanced Security add-on uses custom pricing
  • Only private project lines of code count toward limits
