A detailed comparison to help you choose the right tool for your needs.
Last updated: 2026-02-06
Clerk
Free up to 10k MAU, from $25/mo
Strengths
- + Pre-built React components for auth that actually look good out of the box
- + 10,000 monthly active users free — most startups run free for months
- + Handles the hard stuff: MFA, social login, organization management
Weaknesses
- − Vendor lock-in is real — migrating away from Clerk means rebuilding auth
- − Pricing jumps at scale (10k+ MAU) can surprise you
- − React-focused — less polished for non-React stacks
Stytch
Free up to 25 orgs or 1k MAU, from $99/mo
Strengths
- + Purpose-built for passwordless — magic links, OTPs, passkeys, and biometrics
- + Fraud detection (device fingerprinting, bot detection) included in the platform
- + Clean API design with SDKs for React, Next.js, Python, Go, and more
Weaknesses
- − Paid plans start at $99/mo — expensive compared to Clerk ($25/mo) and Auth0 ($23/mo)
- − Smaller ecosystem and community than established auth providers
- − Traditional email/password auth feels like an afterthought

About each tool
Clerk
Drop-in auth with pre-built UI components — sign-up, sign-in, and user management in minutes
Clerk gives you a complete auth system without building one. Install the package, drop in the sign-up component, and you have Google login, email/password, MFA, and user profiles working. The UI components look professional without any styling work.
The 10,000 MAU free tier is genuinely generous — most early startups will not outgrow it for months. The concern is lock-in: once your app is wired to Clerk’s components and APIs, moving to something else is a significant rewrite. If you are validating an idea and need auth fast, Clerk is the fastest path. If you are building something you expect to maintain for years, consider whether the convenience is worth the dependency.
Stytch
Passwordless authentication API focused on magic links, OTPs, and passkeys
Stytch is built around the idea that passwords are a liability. Instead of email/password as the default, it leads with magic links, one-time passcodes, passkeys, and biometric auth. The API is well-designed — you can have passwordless login working in under an hour. It also bundles device fingerprinting and bot detection, which most competitors charge extra for or do not offer.
The catch is pricing. The free tier covers 1,000 MAU or 25 organizations, but the jump to paid is $99/month — steep for a solo founder who just needs basic auth. If your product specifically benefits from passwordless (fewer support tickets, higher conversion on sign-up), Stytch pays for itself. If you just need standard social login and email/password, Clerk or Firebase Auth give you more MAU for less money.
