🔐 IAM System

Authentication that just works. In 60 seconds.

The open-source alternative to Auth0, Azure AD, and Okta.

---

Why IAM System?

Auth0 and Azure AD have a problem

Auth0:

• Surprise 3-4x price increases at renewal
• $15,000+ annual bills for mid-sized apps
• Complex pricing with hidden fees

Azure AD:

• Premium P2 required for basic features ($9/user/month)
• 5-33% price increases (July 2026)
• Licensing complexity causes overspending

We have a solution

• ✅ Open source - Trust through transparency
• ✅ 60-second setup - Not hours, not days
• ✅ Passkeys-first - Face ID/Touch ID, no passwords
• ✅ Transparent pricing - Free tier: 10,000 MAU, no credit card
• ✅ Drop-in replacement - Migrate from Auth0 in 5 minutes

---

⚡ Quick Start

npx iam init
npm run dev

That's it. You now have:

• ✅ Passkey authentication (Face ID/Touch ID)
• ✅ Protected routes
• ✅ User management
• ✅ Session handling
• ✅ OAuth2/OIDC compliant

No configuration. No complexity. Just works.
