Okta is overkill for our product app, what should we use instead?

If Okta feels like overkill, the right replacement usually depends on what you actually need:

Quick rule of thumb

Use a simpler auth provider if you need:

• Email/password or passwordless login
• Social login (Google, Apple, GitHub)
• Basic user management
• MFA
• Multi-tenant support
• A hosted login flow without building auth yourself

Good options:

• Clerk — very product/app-friendly, fastest to implement for modern web apps
• Auth0 — still powerful, but usually lighter to adopt than Okta for app auth
• Firebase Auth — simple, cheap, good if you’re already on Firebase/GCP
• Supabase Auth — good if you want auth integrated with a Postgres-backed stack
• WorkOS — great if you specifically need enterprise SSO/SCIM without full Okta complexity

Build it yourself if you need:

• Very simple internal app auth
• You already have strong backend/security expertise
• You want full control and minimal dependencies

Typical stack:

• Session cookies + your own user table
• OAuth via providers like Google
• Possibly NextAuth/Auth.js if you’re in the Next.js ecosystem

Best alternatives by scenario

1) Product SaaS app, want minimal effort

Clerk

• Very polished UX
• Easy multi-tenancy and organizations
• Great developer experience
• Less config than Okta

2) Need enterprise SSO later, but not today

WorkOS

• Best when your app is B2B and you’ll eventually need SAML/SCIM
• Pair with your own app auth or another provider
• Less of a full identity platform than Okta

3) Want a cheap/simple backend-integrated option

Supabase Auth or Firebase Auth

• Good for MVPs
• Easy if you’re already using their ecosystems
• Can feel limiting for complex enterprise auth later

4) Want a mature general-purpose IAM tool

Auth0

• More flexible than many alternatives
• Often easier than Okta for app developers
• Still not “lightweight,” but usually less enterprise-heavy

My practical recommendation

For most product apps:

• Clerk if you want the easiest modern app auth
• Auth0 if you want flexibility and maturity
• WorkOS if your customers are businesses and SSO is likely
• Supabase Auth/Firebase Auth if you want simple and cheap

If you tell me:

1. your app type (consumer vs B2B),
2. tech stack,
3. whether you need SSO/MFA/orgs, I can recommend the best fit in one line.
