Why SMBs Are Ditching Traditional Auth
  • 💸 The $50K/Year Login Box Racket

    "Started at $0, now we're at $4,000/month"

    Free tiers vanish overnight. MAU pricing explodes. Every feature costs extra. One viral launch and you're bankrupt.

  • 🤯 Auth0's Complexity Scam

    "3 weeks to implement basic login"

    Callback URLs, tenant configs, rule engines, custom claims... You need a PhD in OAuth just to let users sign up.

  • 🔒 Clerk's Vendor Prison

    "Migration = forcing 50K users to reset passwords"

    Once you're in, you're stuck. Proprietary password hashing, closed systems, no export. They own your users.

"We spent $12,000 on Auth0 last month for features we thought were included. With Passflow, we run it on K8s in production, Lambda for staging, and locally for dev. Same codebase everywhere. It's not even close."

— Sarah Chen, CTO at TechFlow (15K users)

"After our Auth0 bill hit $8K/month, we migrated to Passflow in one weekend. Now we run auth across AWS Lambda, GCP Cloud Run, and on-prem K8s. True multi-cloud at zero cost. Should have switched sooner."

Passflow: Built Different
Actually Free & Open Source

MIT licensed. Self-host anywhere. No "free trial" bait-and-switch. Run on a $5 VPS or serverless Lambda. Your auth, your rules.

Stupidly Fast Setup

One import. One line. You're done. No 47-step integration guides. No "schedule a demo." Just auth that works in 60 seconds.

Passkeys Out of the Box

WebAuthn/FIDO2 built-in. Let users ditch passwords forever. Plus magic links, SMS, TOTP - every auth method, zero setup.

Your Brand, Not Ours

Fully customizable UI components. White-label everything. Drop-in React/Vue components or build your own. It's your app.

Cloud Native Architecture

Deploy anywhere: AWS Lambda, Kubernetes, Docker Swarm, Cloud Run, Vercel Edge. 20MB image, 50MB memory. Works natively in any cloud - no vendor lock-in, infinite scale.

Zero Lock-In Promise
