Firebase is fast to start and hard to leave: a proprietary NoSQL store, Google-hosted, with pricing that gets unpredictable as you grow. Flarelink gives you a similar bundle — auth, database, storage, email — but on a SQL database in your own Cloudflare account, with flat pricing and nothing to migrate off. Here's the honest comparison, including where Firebase still wins.

| Flarelink | Firebase | |
|---|---|---|
| Database | SQL — Cloudflare D1 (SQLite), joins, transactions. | NoSQL — Firestore / Realtime Database (documents). |
| Realtime | Not yet. | Yes — live document subscriptions are Firebase's signature feature. |
| Offline / mobile SDKs | Web-first SDK; no built-in offline sync. | Strong — native iOS/Android SDKs with offline persistence. |
| Auth | Email/password, OAuth (Google, GitHub), magic links, verification. Source-available + verifiable. | Many providers, phone auth, mature. |
| Storage | Cloudflare R2, presigned URLs, zero egress fees. | Cloud Storage; egress billed. |
| Where it runs | Your Cloudflare account. | Google Cloud, fully managed. |
| Pricing | Flat fee + Cloudflare's published rates. No per-op or egress markup. | Per read/write/delete, storage, and egress — scales with usage. |
| Lock-in / exit | Standard SQLite; cancel and your backend keeps running. | Proprietary; migrating off Firestore is a real project. |
| Maturity | Young, in beta. | Very mature, huge ecosystem. |
Firebase's live subscriptions are the reason many apps pick it. Flarelink has no realtime yet, and D1's design means it would be a separate mechanism — not a near-term promise. Chat, collaboration, and live dashboards are squarely Firebase's turf.
Firebase's native SDKs cache and sync offline automatically. Flarelink's client is web-first with no offline layer — if you're building an offline-capable mobile app, Firebase is far ahead.
Schemaless documents let you move fast early. Flarelink is SQL — you define tables and migrations. More structure (and joins, and a typed client), but less "just throw a document in."
Phone auth, analytics, crash reporting, A/B testing, ML kit — Firebase is a whole platform. Flarelink is a focused backend bundle (auth, DB, storage, email), nothing more.
The real work in leaving Firebase is the data-model shift, not the tooling. You'll define SQL tables for what were Firestore collections, and rewrite client-direct queries as server routes that scope each query to the signed-in user (Flarelink is server-first — there's no row-level security to lean on yet). Auth users re-register or are imported as rows. For straightforward CRUD apps this is a clean win; for deeply realtime apps, weigh the gaps above first.
Start with your schema & migrations and the quickstart.
