Hanko

Hanko is open-source authentication for developers, with passkeys, passwords, social login and MFA. Free up to 10,000 monthly active users.

Our take: Hanko makes passkeys the default rather than an add-on, and the free tier is large enough to carry most early products.

What it really isAn open-source, passkey-first authentication service for web apps, available as a cloud service or self-hosted.
Our takeHanko makes passkeys the default rather than an add-on, and the free tier is large enough to carry most early products.
Pricing on Pro is easy to model: a flat $29 plus a cent per extra active user. Two things to plan for. SAML SSO is billed per connection, so B2B apps selling to many enterprises pay per customer. And the backend is AGPL, so if you self-host inside a commercial product, check with your lawyers or budget for Hanko's commercial licence.

Trade-offs

Friction report

Trade-offs to know before signing up.

  1. Time to value
    Short for developers: add the web components and point them at a Hanko Cloud project.
  2. Scale breakpoint
    Above 10,000 MAU, $0.01 per user; each SAML connection adds $49 a month.
  3. Walled garden
    Low: the backend is open source and can be self-hosted.
Still a fit?
If none of these block you, start on the free plan.

Yes. You can run the open-source backend on your own servers, use the managed Hanko Cloud, or ask for a Hanko-managed private cloud on the Enterprise plan.

How do I log in to Hanko Cloud?

Conversion Gems is a review site, not Hanko. Developers sign in to the Hanko Cloud console at https://cloud.hanko.io/login, linked from hanko.io.

Which frameworks does Hanko support?

Hanko publishes guides and starters for React, Next.js, Vue, Nuxt, Angular, Svelte, Remix and Solid. Its login screens are web components, so they work in most frontends.

Is Hanko the same as a Japanese hanko stamp?

No. Hanko at hanko.io is authentication software for developers. The name is shared with the Japanese signature stamp and with a town in Finland.
