Clerk
Fallback auth — 10K MAU free
Clerk
Role
Auth-only fallback if Firebase Auth becomes unavailable.
Free tier
- 10,000 monthly active users
- All social providers + MFA
- Organizations / multi-tenant
- Pre-built React components
Card / subscription required?
NO. Sign-up requires email only.
Alternatives
- Supabase — auth + DB
- Firebase Spark — primary
Swap cost
High — every site’s <AccountPanel> is wired to Firebase. Swap
replaces @chirag127/firebase-init with a Clerk equivalent + leaves
Firestore (no longer paired) needing a new home.
Why fallback only
Lower MAU ceiling than Firebase Auth (10K vs unlimited), and Clerk doesn’t pair with a free database.
