Alpha Status

This feature is still in a (very early!) Alpha status. Here's what that means!

Current Limitations

Since our implementation is still in the early stages, there are a number of limitations:
  • Extensions must be installed on a per-sandbox basis.
  • Settings must be set on a per-sandbox basis.
  • You can only have up to 250MB of extensions installed.
  • The loading of Next Code may fail occasionally (refresh the page if so).
  • There may be bugs in the actual Next Code interface.
  • Not all extensions are available for installation.
  • Next Code projects take about 15 seconds to load vs 2 seconds for a normal sandbox.
  • Some menu options may not make sense, for example there are mentions of "OSX" and "Windows", and "Ctrl+N" will actually open a new browser window, not a new file.

Likely Future Regressions

  • Your extensions in a sandbox will need to be reinstalled.
  • Your settings will need to be reconfigured.
  • The interface is going to change significantly.


  • Any code you write in a Next Code sandbox will be persisted as it would in a normal sandbox.
