## The honest comparison

[Auth0](https://startwithidentity.com/vendors/ciam/auth0/) and [Stytch](https://startwithidentity.com/vendors/ciam/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](https://startwithidentity.com/guides/fundamentals/what-is-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](https://startwithidentity.com/glossary/magic-link/), one-time passcodes, [passkeys](https://startwithidentity.com/glossary/passkey/), 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](https://startwithidentity.com/tools/tco-calculator/).

## Verdict

If login is part of your product experience and you want to own it, [Stytch](https://startwithidentity.com/vendors/ciam/stytch/), especially where passwordless is the strategy. If you want authentication handled with hosted UI, enterprise credibility, and the widest protocol coverage, [Auth0](https://startwithidentity.com/vendors/ciam/auth0/).
