Firebase Environment Doctor is free, open-source software provided under the MIT License. You may use, copy, modify, and distribute it under that license.

A diagnostic, not a guarantee

The doctor reports what it can observe from your local configuration and the optional read-only Firebase CLI results. A ready verdict is a preflight signal, not a guarantee that later Firebase commands are safe or correct. Always review the displayed project ID before changing cloud data or deploying configuration.

No affiliation

This project is an independent developer tool. It is not affiliated with or endorsed by Google or Firebase. Firebase is a trademark of Google LLC.

No warranty

The software is provided “as is,” without warranty of any kind, as described in the repository's MIT License. The CLI intentionally performs no repair, deploy, or other mutating Firebase command.
