Introducing Auth.it — Modern Authentication Built on Keycloak, at a Fraction of the Cost

Auth.it

Today, we’re excited to introduce Auth.it, a modern authentication platform built for developers who want the power of Keycloak with the simplicity, polish, and developer experience of modern identity providers like WorkOS, Stytch, and Clerk — all at a fraction of the cost.

Why We Built Auth.it​

Modern authentication is a solved problem — but it’s still too expensive and often too restrictive.

Developers love the flexibility and security of Keycloak, but managing it at scale is complex. Meanwhile, modern SaaS auth platforms like WorkOS, Clerk, and Frontegg offer a smooth developer experience but come with:

  • High per-user or per-organization pricing
  • Vendor lock-in
  • Limited self-hosting or data control

We built Auth.it to give you the best of both worlds: enterprise-grade, open-source security powered by Keycloak, wrapped in a developer-first SaaS platform that’s easy, fast, and affordable.

What Makes Auth.it Different​

🧱 Built on Keycloak​

At its core, Auth.it runs a fully compatible Keycloak engine. That means:

  • Open standards (OIDC, SAML, SCIM)
  • Enterprise integrations out of the box
  • No vendor lock-in — you can export your data anytime

⚙️ Developer-First Experience​

We’ve reimagined what it’s like to work with Keycloak:

  • Modern APIs and SDKs for quick setup
  • Instant SSO, Passwordless, and Magic Links
  • Organization and user management baked in
  • Clear, simple docs: docs.auth.it

💸 80% Lower Cost​

Auth.it is designed to be cost-efficient, leveraging our optimized Keycloak infrastructure and transparent pricing. You get modern authentication capabilities without paying enterprise prices.

☁️ Fully Managed Hosting​

No servers to patch, no clusters to maintain — we handle the infrastructure, scaling, and updates, so you can focus on your product.

Who Auth.it Is For​

Auth.it is built for:

  • Developers and startups who want modern auth without high costs.
  • Engineering teams already familiar with Keycloak who want a managed experience.
  • SaaS platforms that need SSO, MFA, and user management that scales affordably.

If you’re building a new app, migrating off Auth0 or Clerk, or trying to modernize your Keycloak setup — Auth.it makes it simple.
