What does API-first actually mean for Stytch?

That you build the interface and Stytch provides the authentication primitives behind it: magic links, one-time passcodes, passkeys, OAuth connections, and session management as APIs and SDKs. There are pre-built components available, but the product is designed on the assumption that you want control of the experience rather than a hosted page.

Is Stytch better for passwordless?

It is more focused on it. Passwordless is Stytch's founding premise rather than a capability added to a password-centric platform, and its magic link, OTP, and passkey flows are first-class with fraud and device fingerprinting available alongside. Auth0 supports all the same methods competently, but its defaults and documentation still assume passwords more often.

Which has better enterprise support?

Auth0, on distribution, certifications, and the diligence posture that comes with Okta ownership, plus dedicated private cloud for residency requirements. Stytch is a younger private company. If enterprise procurement is a gate on your deals, that difference shows up in security questionnaires rather than in the product.

Can we migrate from Auth0 to Stytch?

Yes, and Stytch publishes migration tooling for it. The hard parts are the usual ones: password hashes need to transfer or users need to reset, MFA enrolments generally do not migrate, and sessions have to be cut over. Plan for a dual-run period rather than a single switch.

The honest comparison

Auth0 and Stytch score 4.6 and 4.3, and the real question between them is whether you want a platform or a toolkit.

Auth0 is the platform. Hosted login pages, a rules and Actions engine, custom database connections, the widest protocol coverage in CIAM, and the enterprise posture that comes with being part of Okta. You can build a compliant, capable login without writing much UI.

Stytch is the toolkit, built passwordless-first. Magic links, one-time passcodes, passkeys, OAuth connections, and session management exposed as clean APIs, with fraud and device fingerprinting available as separate features. Components exist, but the product assumes you want to own the experience.

That difference is strategic rather than technical. Teams that treat login as part of the product and want pixel control choose Stytch. Teams that want authentication solved and out of the way choose Auth0.

When Auth0 wins

You want a full platform with hosted UI rather than building the experience yourself
Protocol breadth and enterprise federation scenarios matter
Enterprise certifications, diligence posture, and data residency options are gating deals
Migration off a legacy store using custom database connections
Mixed B2C and B2B in one product

When Stytch wins

You are building custom login UI and want clean primitives rather than a hosted page
Passwordless-first is the strategy, with magic links, OTP, and passkeys as defaults
Fraud signals and device fingerprinting are requirements you would otherwise buy separately
Transparent usage-based pricing you can model line by line

Pricing

Auth0 has a free tier then per monthly active user tiers that escalate, with capabilities gated behind higher plans, so the feature boundaries drive cost more than volume does.

Stytch publishes transparent usage-based pricing with a free tier, billed across active users and specific features such as fraud and device fingerprinting. That makes it predictable, provided you check which line items you actually need, since the add-on features are where the cost varies. Model both with the TCO calculator.

Verdict

If login is part of your product experience and you want to own it, Stytch, especially where passwordless is the strategy. If you want authentication handled with hosted UI, enterprise credibility, and the widest protocol coverage, Auth0. See Clerk vs Stytch, best passwordless CIAM providers, and what is passwordless.
