  • 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.

Moonrepo

  • Smaller community compared to established build systems like Bazel
  • Limited integrations with enterprise CI/CD platforms
  • Documentation gaps in some advanced use cases
  • No commercial support option for organizations requiring guaranteed SLAs
