Why teams connect Dynamo DB and Firebase

Keep Dynamo DB and Firebase 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 Dynamo DB and Firebase 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

  • Sync customer records between DynamoDB-backed services and a CRM so support and sales see live application state.
  • Mirror SaaS objects into DynamoDB items to serve low-latency lookups from production services.
  • Sync Firestore user and account documents into a CRM so go-to-market teams see live product data.
  • Mirror Firestore collections into Postgres or a warehouse to run SQL analytics on app data.

Cross-engine sync

Keep the same dataset live in both Dynamo DB and Firebase, 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 Dynamo DB and Firebase

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.

Dynamo DB objects Firebase objects
Tables The top-level containers a sync targets; each table is addressed independently. Firestore Collections Top-level groupings of documents that a sync maps to tables or SaaS objects.
Items Schemaless records keyed by partition (and optional sort) key, mapped to rows or SaaS objects in syncs. Firestore Documents Schemaless JSON-like records, the primary unit synced to and from external systems.
Attributes Per-item fields, including nested maps and lists, flattened or mapped during sync. Subcollections Nested collections under documents, typically flattened into related tables during sync.
Partition and Sort Keys The primary key pair used as the match key for bi-directional sync. Realtime Database Nodes JSON tree paths in the older Realtime Database, synced by path.
Global Secondary Indexes Alternate access paths used when sync queries filter on non-key attributes. Authentication Users User accounts read into CRMs and warehouses for customer records.
DynamoDB Streams Ordered item-level change records consumed for incremental sync. Cloud Storage Objects Files referenced from documents; usually synced as metadata plus URLs.
What ships with Dynamo DB ⇄ Firebase

How it works

How to connect Dynamo DB to Firebase — 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.

  1. 01

    Connect your apps

    Authenticate Dynamo DB and Firebase with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.

    Choose tables

    Pick the Dynamo DB and Firebase objects to sync — Stacksync auto-detects both schemas, including custom fields where the platform exposes them. Sync to existing tables, or let Stacksync create new ones with ideal data types.
