Firebase

Firebase brand colours

Extracted from the artwork and ranked by how much of the mark each covers, not from a brand book, so treat them as observed rather than official.

Firebase is the original realtime backend and still the most operationally proven. Firestore is a document store with live listeners and genuine offline persistence, wrapped in the best mobile SDKs on this list. Access control is a proprietary rules language evaluated per document. Nothing is self-hostable, there is no SQL, and the managed export format is readable only by Firestore's own importer.
