EnglishHow Does Hanko Compare to Auth0, Clerk, Firebase Auth, AWS Cognito, and Keycloak?
Updated
Hanko positions itself as an open-source, privacy-first authentication and user management platform for modern apps, and explicitly markets itself as a developer-friendly alternative to Auth0, Clerk, Firebase Auth, AWS Cognito, and Keycloak. The practical difference it emphasizes is control: you can move between self-hosted and Hanko Cloud at any time, with no vendor lock-in, and you keep full control over your data. If your selection criteria are "open source, data ownership, and the ability to leave without a rewrite," Hanko is built around exactly those. If you need a mature managed ecosystem with the broadest integration catalog, the incumbents still have more surface area to check.
The comparison at a glance
| Dimension | Hanko | Auth0 / Clerk / Firebase Auth / AWS Cognito / Keycloak |
|---|---|---|
| Source model | Open source | Mostly proprietary managed services; Keycloak is open source |
| Data control | Full control over your data, per Hanko's positioning | Varies; managed services typically hold identity data in their cloud |
| Deployment flexibility | Move between self-hosted and Hanko Cloud anytime | Keycloak is self-hosted; the managed services are cloud-only |
| Lock-in | Explicitly "no lock-in" | Managed services carry migration cost; Keycloak does not |
| Modern auth methods | Passkeys, 2FA, SSO, and more | All support comparable methods, with different depth per product |
| Positioning | Developer-friendly alternative to the above | Established platforms with large ecosystems |
The table reflects how Hanko describes itself. Treat the incumbent column as directional rather than a feature-by-feature audit — verify each capability against the specific vendor's current docs before deciding.
Where Hanko's differences actually matter
Open source and data ownership
Hanko's core claim is that it is open source and privacy-first, with full control over your data. For teams in regulated industries, or teams whose customers ask where identity data lives, that is a structural difference rather than a feature checkbox. With most managed identity providers, your user records live in the vendor's cloud; with Hanko, self-hosting puts them in your infrastructure.
No lock-in, and switching between self-hosted and cloud
The stated ability to "move between self-hosted and Hanko Cloud anytime" is the most concrete anti-lock-in argument. It means the deployment decision is not permanent: you can start on Hanko Cloud and migrate to self-hosted (or the reverse) without changing your auth model. Compare that to a managed-only provider, where leaving means exporting users and re-integrating a different SDK.
Modern authentication methods
Hanko supports passkeys, 2FA, and SSO. The product surface shown in its own UI flows includes:
- Passcode login — enter a code sent to your email address, with a resend option.
- Login method selection — password, passcode, or passkey.
- MFA setup — security keys or an authenticator app, with a skip option.
- Account creation — email, or continue with Google.
- Sign in — the standard entry point.
These are the flows your users actually see, which makes them a fair proxy for what "supported" means in practice.
How to choose
Use the following conditions rather than a single winner:
- Choose Hanko if open source, data control, and avoiding lock-in are your top criteria, and you want the option to self-host or use the cloud without committing permanently.
- Choose a managed incumbent if you want the largest integration ecosystem and are comfortable with identity data living in a vendor cloud.
- Choose Keycloak if you specifically want an open-source, self-hosted option and are prepared to operate it yourself — it is the closest philosophical match to Hanko in this list, but Hanko's differentiator is the cloud/self-hosted portability and its modern passkey-first flows.
What to verify before committing
Hanko's own page states "Try Hanko for free" with "No credit card required," and links to a pricing page. Pricing tiers, limits, and any paid-plan terms are not specified in the material available here, so check the pricing page directly for current numbers.
Before deciding, confirm:
- Which auth methods you need (passkeys, 2FA, SSO) and whether Hanko's flows cover your exact requirements.
- Your deployment target — self-hosted, Hanko Cloud, or both over time.
- Migration path: how you would export users and move off, and how you would move between self-hosted and cloud.
- Current pricing and any usage limits on the pricing page.
The honest summary: Hanko competes on openness, data control, and portability rather than on having the largest ecosystem. If those three things are your selection criteria, it is a direct fit; if ecosystem breadth is, compare carefully against the specific incumbent you are considering.
