Why teams connect Firebase and MariaDB
Keep Firebase and MariaDB synchronized in real time, across engines, regions, or services, in one or both directions.
Two databases that must agree is one of the oldest problems in engineering: different engines for different workloads, separate services with overlapping reference data, a migration in flight, or regional instances that share a subset of records. Hand-rolled replication across systems means change capture, conflict handling, and type mapping, all built and maintained by your team.
Stacksync syncs tables or collections between Firebase and MariaDB continuously and bi-directionally, translating types between the two engines and resolving conflicts by rules you configure. Rows written on either side appear on the other within seconds.
Common use cases
- Replace one-off Cloud Functions export code with managed, continuous sync.
- Sync Firestore user and account documents into a CRM so go-to-market teams see live product data.
- Two-way sync between a MariaDB application database and a CRM so both systems hold the same customer records
- Replicate ERP or billing master data into MariaDB databases that power customer-facing applications
Cross-engine sync
Keep the same dataset live in both Firebase and MariaDB, so each workload runs on the engine that suits it.
Migration with zero-downtime cutover
When one database is replacing the other, sync both directions during the transition and switch traffic when ready, without a freeze window.
Shared reference data between services
Services that own separate databases stay consistent on the records they share, without a custom replication layer.
What you can sync between Firebase and MariaDB
Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.
| Firebase objects | MariaDB objects | |
|---|---|---|
| Authentication Users User accounts read into CRMs and warehouses for customer records. | JSON Columns Semi-structured payloads validated with JSON functions. | |
| Cloud Storage Objects Files referenced from documents; usually synced as metadata plus URLs. | Stored Procedures Server-side logic that can post-process synced rows. | |
| Cloud Functions Triggers Server-side hooks that fire on document changes and can push updates outward. | Databases (Schemas) Top-level namespaces that scope a sync's reads and writes. | |
| Firestore Collections Top-level groupings of documents that a sync maps to tables or SaaS objects. | Tables The primary sync target; rows map to records in connected systems. | |
| Firestore Documents Schemaless JSON-like records, the primary unit synced to and from external systems. | Views Read-side projections used as outbound sync sources. | |
| Subcollections Nested collections under documents, typically flattened into related tables during sync. | Columns Field-level mapping targets with engine-typed values. |

EDI
Transform legacy EDI complexity into simple database interactions between Firebase and MariaDB.
How the Firebase and MariaDB connectors work
Firebase
- Integration surface
- REST and gRPC APIs, typically accessed through the Firebase Admin SDK
- Authentication
- Google service account credentials (IAM) for server-side access; Firebase Auth tokens for client contexts
- Change detection
- Real-time snapshot listeners on Firestore queries and Cloud Functions triggers on document changes
- Capabilities
- read · write
- Rate limits
- Subject to Firestore's documented operation quotas and per-document write throughput limits
MariaDB
- Integration surface
- SQL wire protocol (MySQL-compatible client/server protocol)
- Authentication
- Database credentials (connection string or parameters), with optional SSL root certificate upload and optional SSH tunnel (SSH user + host)
- Change detection
- Database triggers — Stacksync creates deterministic triggers for internal logging and syncing
- Capabilities
- read · write · CDC
- Rate limits
- No API rate limits; throughput is bounded by connection limits and server resources
How it works
How to connect Firebase to MariaDB — three steps, no code
Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.
- 01
Connect your apps
Authenticate Firebase and MariaDB with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.

FAQ
Firebase and MariaDB integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Firebase and MariaDB: authenticate both systems, choose the objects to sync (such as Firebase's Authentication Users and Cloud Storage Objects), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Firebase and MariaDB records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Firebase and MariaDB connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Firebase–MariaDB integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Firebase and MariaDB. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Firebase: Real-time snapshot listeners on Firestore queries and Cloud Functions triggers on document changes. On MariaDB: Database triggers — Stacksync creates deterministic triggers for internal logging and syncing. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the Firebase side: Cloud Storage Objects, Cloud Functions Triggers, Firestore Collections, Firestore Documents, plus custom fields where Firebase exposes them. On the MariaDB side: Databases (Schemas), Tables, Views, Columns. Stacksync auto-detects both schemas and converts types between the two systems.
