Clerk - Pros & Cons
Pros
- ✓Drop-in React components are the most polished in the auth space — you ship a branded auth flow in hours
- ✓MRU-based pricing aligns costs with retained users instead of every signup or active user
- ✓Billing add-on bundles auth + subscriptions + self-service portals on top of Stripe with prebuilt UI
Cons
- ✗Costs scale fast past 1M MRUs vs. rolling your own auth on Supabase or a JWT library
- ✗Enterprise SSO is $75/mo per connection on Pro, which compounds if you sell to many enterprises
- ✗No public MCP server yet — agent integrations still go through the REST API
Stytch - Pros & Cons
Pros
- ✓Generous free tier covers 10,000 MAUs with full feature access including passwordless, OAuth, MFA, and SSO
- ✓No pricing cliffs or tier jumps: pay per unit above the free threshold for predictable cost scaling
- ✓API-first approach gives developers full control over the authentication UX without widget constraints
- ✓Strong passwordless support with passkeys, WebAuthn, magic links, and OTPs reduces password-related security risks
- ✓B2B product with per-organization SSO and SCIM is purpose-built for multi-tenant SaaS applications
- ✓Device fingerprinting enables risk-based authentication decisions without relying on cookies
Cons
- ✗No pre-built login UI components means more frontend development work compared to Clerk or Auth0
- ✗Opaque per-unit pricing beyond the free tier requires contacting sales for exact rates at scale
- ✗Smaller ecosystem and community compared to Auth0/Okta, meaning fewer tutorials and community extensions
- ✗Self-hosted deployment not available: all authentication flows route through Stytch's infrastructure
- ✗Migration from Stytch requires rebuilding auth flows since the API is proprietary, not standards-based
