“Best consistent API experience across React Native and Flutter: Supabase.”
“Verdict: Probably the most attractive choice if you want a consistent developer experience between React Native and Flutter.”
“Supabase: Best balance of SDK consistency, database capabilities and cross-platform development.”
“Supabase is particularly interesting because it provides official libraries for both JavaScript/TypeScript and Dart.”
“The matrix also reports 65% overall parity across all its core SDKs, meaning there are still differences between implementations.”
“Best overall cross-platform SDK ecosystem: Firebase.”
“Firebase has one of the most comprehensive mobile development ecosystems.”
“Verdict: Excellent mobile coverage, especially Flutter.”
“Firebase: Best-established mobile ecosystem, especially if push notifications, analytics and crash reporting are important.”
“One important caveat: React Native Firebase is maintained by the community, not an official Firebase SDK covered by Google's Firebase support.”
“Best dedicated SDK coverage for both frameworks: Appwrite.”
“Appwrite has an advantage over many competitors: it maintains dedicated official SDKs for both React Native and Flutter.”
“This demonstrates active maintenance, although version numbers alone don't establish feature parity.”
“Appwrite also documents its SDK compatibility with different server versions, which is useful if you're self-hosting.”
“Best for an AWS-centric architecture: Amplify.”
“Amplify is a good option if your infrastructure is already built around AWS.”
“The React Native libraries have a reasonably comprehensive feature set, although individual categories have different platform capabilities.”
“Verdict: Good for AWS-based applications, but less attractive if your main requirement is consistent SDK functionality across React Native and Flutter.”
