Why teams connect Firebase and Nutshell

Treat Nutshell like part of your database: its records live in Firebase as real tables, and writes in either place sync to the other in seconds.

Product and engineering teams constantly need CRM data, and the CRM API is a poor way to get it: rate limits, pagination, custom objects, and integration code that breaks when an admin renames a field. What they actually want is the data in Firebase, where it can be queried and joined like everything else.

Stacksync mirrors Companies, Activities, Tasks, Notes from Nutshell into Subcollections, Realtime Database Nodes, Authentication Users, Cloud Storage Objects in Firebase with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Nutshell with validation intact. Go-to-market teams keep working in the CRM, engineers keep working in the database, and neither has to think about the other.

Common use cases

  • Push closed-won leads to accounting software to trigger invoicing automatically.
  • Keep People and Companies consistent between Nutshell and email marketing or outreach tools.
  • 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.

Query the CRM like a database

Accounts, contacts, and custom objects from Nutshell become tables in Firebase you can join with application data directly.

Product events onto CRM records

Signup, usage, or lifecycle changes written to Firebase sync onto the matching records in Nutshell, giving go-to-market teams live product context.

Internal tools without API code

Back-office apps read and write the synced tables; Stacksync handles the Nutshell API, limits, and retries.

What you can sync between Firebase and Nutshell

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 Nutshell objects
Authentication Users User accounts read into CRMs and warehouses for customer records. Leads Nutshell's deal object; synced as the pipeline record linked to people and companies
Cloud Storage Objects Files referenced from documents; usually synced as metadata plus URLs. People Individual contacts, kept consistent with marketing and outreach tools
Cloud Functions Triggers Server-side hooks that fire on document changes and can push updates outward. Companies Account records that group people and leads for account-level syncs
Firestore Collections Top-level groupings of documents that a sync maps to tables or SaaS objects. Activities Logged calls, meetings, and emails used for engagement reporting
Firestore Documents Schemaless JSON-like records, the primary unit synced to and from external systems. Tasks Rep to-dos mirrored into external work-management or reporting systems
Subcollections Nested collections under documents, typically flattened into related tables during sync. Notes Free-text history attached to leads and contacts, replicated for a full timeline
