I work on the Firebase team and have been working on the Firebase Emulator Suite for the past year or so. We really want every Firebase developer to be able to run their app locally and offline, although I'll be the first to admit there are rough edges.

If you or anyone else wants to discuss this more and give us some specific feedback on what went wrong, please reach out:

  * https://groups.google.com/g/firebase-talk - our mailing list, good for open-ended discussion
  * https://github.com/firebase/firebase-tools - GitHub repo for the Firebase CLI and emulators if you have specific bugs to report.

Or if you want to reach me personally I'm [email protected], always happy to chat 1:1 about this stuff.
