Firebase alternative
About Firebase: Google's backend-as-a-service for apps.
People leave Firebase for a few recurring reasons: the bill grew faster than the project, a free tier changed, or they want something they can run locally or self-host. Speed matters too, both how fast the tool itself feels and how quickly you go from install to first result. Check what the alternative stores in your repo versus its own cloud, how it handles teams and secrets, and whether there is a CLI or API for scripting.
Positioning is from each listing, not an endorsement.
