Frequently Asked Questions

Why migrate from Firebase to Supabase?

Supabase offers an open-source, PostgreSQL-based alternative with no vendor lock-in. You get full SQL capabilities, Row Level Security, and the ability to self-host. Pricing is more predictable for read-heavy workloads since Supabase does not charge per-read.

How does Nivo handle the NoSQL to SQL conversion?

Nivo analyzes your Firestore document structures, identifies common fields and nested objects, and generates normalized PostgreSQL table schemas. Nested subcollections become related tables with foreign keys. Each conversion is reviewable.

How long does a Firebase to Supabase migration take?

Code migration typically completes in 15 to 25 minutes. Data migration depends on your Firestore data volume. Nivo focuses on the application code transformation; data export/import uses the Supabase migration toolkit.

What about Firebase Cloud Messaging (FCM)?

Supabase does not have a built-in push notification service. Nivo flags FCM usage and recommends alternatives like OneSignal or direct FCM integration, since FCM can be used independently of Firebase's database.

Will my authentication users transfer?

User accounts can be exported from Firebase Auth and imported into Supabase Auth. Nivo updates all auth-related code, and Supabase provides migration scripts for user data including password hashes.
