AuthJetAuthJet vs. Clerk
Clerk is excellent if you're building a React/Next.js app and want prebuilt UI components. AuthJet is built API-first for teams whose product is inherently multi-tenant — think B2B SaaS with customer accounts, seats, and per-tenant roles — regardless of frontend framework.
| Topic | AuthJet | Clerk |
|---|---|---|
| Best fit | Multi-tenant B2B SaaS that wants tenant/role isolation as a first-class concept | Next.js/React apps that want drop-in prebuilt UI components fast |
| Integration style | Plain REST API — call it from any backend or language | Framework-specific SDKs and prebuilt React components |
| Multi-tenancy | Built in: accounts, tenants, and per-tenant roles from the start | Supported via Organizations, added on top of the core user model |
| Pricing | Flat plans by seats/environments, visible on one page | Free up to a generous MAU limit, then per-MAU pricing |
| Prebuilt UI | Hosted login page on paid plans; otherwise bring your own UI | Rich prebuilt components (SignIn, UserButton, etc.) — a real strength for fast frontend integration |
