When to pick Firebase
Deepest Google Cloud integration and the most battle-tested mobile auth SDK. The vendor lock-in is real; plan for it.
- You need deep Google Cloud integration and the most battle-tested mobile auth SDK.
- Your team is already invested in Firebase's SDK and ecosystem.
When to pick kynetradb
- You want a comparison-led conversation about BM25 full-text, vector evaluation, and data-plane trade-offs.
- You need a product-specific implementation scope rather than a generic migration claim.
- You want to assess 19 hosting target profiles, including 5 Indian providers.
- You want a scoped preview conversation about the data, deployment, and operating boundary.
- You need to run on your own infra — Firebase is managed-only.
- You want a single binary with no runtime dependencies — no container fleet to operate.
