Verdict

Auth0 Free at 7,500 active users is honest. Above that threshold, Essential at $35/mo for 1,000 MAUs jumps the price-per-MAU dramatically. Clerk at 10,000 free MAUs and $25 base afterwards is the deepest modern alternative for B2C; Supabase Auth bundles 50K free MAUs with Postgres; WorkOS is free up to 1M MAUs for AuthKit; Stytch and Logto round out the field.

By Subrupt EditorialPublished Reviewed

The Okta acquisition of Auth0 in 2021 changed the developer-side perception of the product. Pricing tightened on the way to enterprise sales motion; the free tier got new MAU caps; the dashboard added Okta-style controls some developers found friction-heavy. Many SaaS teams running early-stage products started evaluating alternatives between 2022 and 2024 once they crossed Auth0's free tier.

Here is the math. A SaaS with 5,000 monthly active users on Auth0: Free covers it (7,500 MAU cap). At 10,000 MAUs: Essential B2C at $35/mo includes only 1,000 MAUs; the per-MAU cost balloons. Same SaaS on Clerk: 10K MAUs free, then $25 base + $0.02 per MAU above 10K. Same on Supabase Auth: 50K MAUs free as part of the Pro project at $25/mo (which also gives you Postgres, storage, edge functions, and realtime). The difference compounds quickly.

Where each alternative fits. B2C SaaS with React or Next.js: Clerk. Postgres-native team that wants auth bundled with database: Supabase Auth. Selling to enterprises that need SAML SSO and SCIM: WorkOS. Pay-as-you-grow with broad auth methods: Stytch. Self-host imperative: Logto.

Our picks for Auth0 (Okta) alternatives

#1

Clerk

Free tierMedium switching effort

Best for B2C SaaS with React or Next.js

Try Clerk

Clerk is built around the React component model and ships pre-built UI for sign-in, sign-up, user management, and organizations. The free tier covers 10,000 MAUs (8,500 above Auth0's threshold) and Pro is $25 base plus $0.02 per MAU after, which keeps the price predictable as you scale. For a 50K-MAU SaaS, Clerk Pro is $25 + $0.02 × 40,000 = $825/mo total; the same scale on Auth0 Professional B2C tier crosses $1,000 quickly with overage. Clerk's organization model also handles B2B SaaS multi-tenancy without bolting on a separate $100/mo add-on.

Strengths

  • +10K free MAUs (8.5K above Auth0)
  • +Pre-built React components for all auth flows
  • +Predictable Pro pricing ($25 + $0.02/MAU)
  • +Organizations primitive for B2B SaaS

Trade-offs

  • −Newer brand than Auth0 (less enterprise procurement recognition)
  • −Per-user-month pricing on Pro climbs at very high MAUs
  • −B2B SaaS add-on is a separate $100/mo
Free

Migration steps
  1. Sign up at clerk.com (free).
  2. Set up Clerk Auth in a parallel branch of your application.
  3. Migrate user records via Clerk's import API; map password hashes (bcrypt supported).
  4. Run two weeks side by side; cut traffic over to Clerk once login success rates match Auth0.

Not for: Avoid Clerk when you specifically need Auth0 Actions or Auth0 Rules for legacy enterprise customizations; the Clerk middleware model is similar but not a drop-in replacement.

#2

Supabase Auth

Free tierHigh switching effort

Best when auth should bundle with Postgres database

Try Supabase Auth

Supabase Auth is included with every Supabase project. The Pro project at $25/mo covers 100,000 MAUs included in base, then $0.00325 per MAU above. Plus you get Postgres with Row Level Security, storage, edge functions, and realtime in the same project. For new SaaS that does not yet have a database, the bundle math beats running Auth0 plus a separate Postgres host. The trade-off is vendor concentration: Supabase becomes both your auth and your database.

Strengths

  • +50K free MAUs on the free Supabase project
  • +100K MAUs included in Pro at $25/mo
  • +Bundled with Postgres + storage + realtime
  • +Row Level Security primitives for fine-grained access

Trade-offs

  • −Vendor concentration (auth and DB on one provider)
  • −Less suited for adding to an existing non-Postgres app
  • −Enterprise tier requires custom contract

Migration steps
  1. Set up a Supabase project (free or Pro).
  2. Enable the auth methods you need (email, OAuth, magic links, OTP).
  3. Migrate users via the Supabase Auth Admin API; password hashes (bcrypt) port over.
  4. Update application JWT validation to Supabase's; cancel Auth0 once cutover is verified.

Not for: Pass on Supabase Auth if your application is not Postgres-shaped; the bundling advantage disappears outside the Supabase stack.

#3

WorkOS

Free tierMedium switching effort

Best for SaaS selling to enterprises (SAML SSO + SCIM)

Try WorkOS

WorkOS is free up to 1 million MAUs on AuthKit, which means most B2C startups never pay for auth. The revenue model is enterprise add-ons: SAML SSO, SCIM directory sync, and audit logs. For SaaS whose enterprise sales motion requires SSO support, WorkOS is the right pick and is appreciably cheaper than Auth0 Enterprise (which gates SAML SSO at higher tiers with custom enterprise contracts). The trade-off is that the free tier excludes the enterprise features you would eventually buy.

Strengths

  • +Free up to 1M MAUs on AuthKit
  • +SAML SSO + SCIM purpose-built for B2B SaaS
  • +Magic Auth and MFA included free
  • +Strong audit logs on Enterprise

Trade-offs

  • −Free tier excludes the enterprise features you eventually need
  • −Enterprise pricing not transparent (custom quote)
  • −Smaller community than Auth0

Migration steps
  1. Sign up at workos.com (free).
  2. Implement AuthKit for the consumer-side authentication flow.
  3. Add SAML connections per enterprise customer; quote each connection separately.
  4. Migrate existing Auth0 users via WorkOS user import API.

Not for: WorkOS is overkill if you have no B2B enterprise sales motion; Clerk or Stytch cover B2C-only at lower combined cost.

#4

Stytch

Free tierMedium switching effort

Best for pay-as-you-grow with broad auth methods

Try Stytch

Stytch is free up to 10,000 MAUs, then $0.05 per MAU. The pricing model is simple and the breadth of auth methods (passkeys, magic links, OTP, social, SSO, biometrics) is comparable to Auth0 without the tier-jumping. For a 50K-MAU SaaS, Stytch costs $40,000 × $0.05 = $2,000/mo... actually that math demonstrates the cost ceiling. Stytch gets cheaper than Auth0 for moderate volumes (10K-50K MAU) but converges with Auth0 at high scale. The platform has volume discounts above 50K not visible on the public pricing page.

Strengths

  • +10K free MAUs
  • +$0.05 per MAU is predictable below 50K
  • +Broad auth methods including biometrics
  • +Embedded magic links built in

Trade-offs

  • −Per-MAU cost above 50K can climb without volume discounts
  • −Smaller marketplace than Auth0
  • −Newer brand than Auth0 or Clerk
Free

Migration steps

  2. Pick the auth methods that match your existing Auth0 setup.
  3. Migrate users via Stytch's user import API.
  4. Cut traffic over once login flows verify in production.

Not for: Pass on Stytch if your MAU count is consistently above 50K; the per-MAU math makes Clerk Pro or WorkOS more predictable at high volume.

#5

Logto

Free tierHigh switching effort

Best for self-host with all auth features

Try Logto

Logto is open source under MPL-2.0 with both a free cloud tier (5,000 MAUs) and free unlimited self-host. The hosted Hobby tier at $16/mo covers 10K MAUs with $0.026 per MAU above; Pro at $96 covers 50K MAUs included with SAML SSO and custom domains. For organizations whose security posture or compliance requires self-host, Logto is the right call and Auth0 Enterprise's pricing is overkill for that constraint.

Strengths

  • +MPL-2.0 license self-host free
  • +5K free MAUs on cloud
  • +All major auth methods including SAML SSO on Pro
  • +Pre-built sign-in UI

Trade-offs

  • −Self-host requires Docker plus Postgres operations
  • −Smaller community than Auth0 or Clerk
  • −Limited B2B-specific features vs WorkOS
Free cloud
5,000 MAUs
Hobby
$16/mo + $0.026/MAU above 10K
Pro

Migration steps
  1. Decide self-host (Docker + Postgres) or Logto Cloud.
  2. Configure auth methods to match your Auth0 setup.
  3. Migrate users via Logto's bulk import API.
  4. Cut auth-protected routes to Logto JWTs; cancel Auth0 once routing is verified.

Not for: Logto is the wrong choice if you do not have DevOps capacity for self-host and Cloud Pro at $96 still under-covers your MAUs; Clerk or Stytch are sized better for hosted convenience.

How we picked

Auth0 alternatives are scored on the build-vs-buy axis (managed vs self-host), the pricing model (per-MAU vs flat-base-plus-MAU vs per-org), and the customer shape (B2C, B2B SaaS, enterprise procurement). Each pick leads on one combination.

Pricing is taken from each vendor's site on the review date. Per-MAU costs scale very differently between providers as MAU grows; we ran 5K, 10K, 50K, and 100K scenarios when comparing.

Frequently asked questions about Auth0 (Okta) alternatives

What is a Monthly Active User (MAU) in auth pricing?

An MAU is a unique user who authenticates at least once in a calendar month. Most providers count MAU on the user record, not per-session. A user logging in 50 times in a month counts as 1 MAU. Authentication providers structure pricing around MAU because it scales with your application's actual usage.

Is Auth0 still the safe choice for enterprise procurement?

Often yes. Okta's brand recognition with enterprise security teams is real and shortens procurement cycles. WorkOS is the alternative gaining the most traction for SaaS startups whose enterprise customers require SAML SSO; the implementation pattern (per-connection pricing) maps to the sales motion.

Can I migrate user passwords between auth providers?

Most providers support importing bcrypt password hashes from Auth0 directly (Clerk, Supabase, Stytch, Logto). Argon2 and other formats may require users to reset on first login. Plan for some percentage of users to land on a forgot-password flow during the migration window.

What is the practical difference between Clerk and Stytch?

Clerk ships pre-built React components and is opinionated about the front-end experience; Stytch is more API-first and assumes you build your own UI. For React/Next.js teams, Clerk reduces front-end work; for teams with their own design system, Stytch is more flexible.

Can I really self-host Logto for production?

Yes. Logto is in production at multiple SaaS companies. The self-host stack is Docker plus Postgres plus a public TLS endpoint. Operating it requires DevOps capacity but is straightforward for teams already running Docker workloads. The trade-off vs Logto Cloud Pro is paying with engineering time instead of dollars.
