-
Auth0
IdentityAuthentication and authorization platform.
Auth0 sits in the premium tier of the identity-as-a-service space, competing directly with Okta (which owns them), Firebase Auth, and Clerk. They're not the cheapest option — Clerk and Firebase undercut them at lower MAU counts — but they're selling on compliance depth, extensibility, and brand trust with enterprise buyers.
Plans: Free $0/mo · Essentials $35/mo · Professional $240/mo · Enterprise Contact Sales
-
Clerk
IdentityAuthentication for modern apps.
Clerk sits mid-to-premium in the auth-as-a-service space — more expensive than rolling your own with Auth0's free tier or using Supabase Auth, but they're betting on developer experience and B2B feature depth to justify it. They're clearly targeting VC-backed startups, hence the Stripe Atlas and YC discount pipeline.
Plans: Hobby $0/mo · Pro $25/mo · Business $300/mo · Enterprise Contact Sales
-
Descope
IdentityNo-code authentication flows.
They're positioned as a mid-market alternative to Auth0 and Okta — cheaper than Okta's enterprise lock-in, more feature-rich than rolling your own. The Hello World startup program is a direct shot at Auth0's free tier dominance in the developer-first space.
Plans: Free Forever $0/mo · Pro $249/mo · Growth $799/mo · Enterprise Contact Sales
-
Duo Security
IdentityMFA and device trust from Cisco.
At $3–$9/user/month, Duo sits in the affordable-to-mid range for identity security — well below Okta's MFA add-ons and competitive with Microsoft Authenticator bundles for orgs not already in the M365 ecosystem. They're clearly targeting security-conscious SMBs and mid-market teams that want enterprise-grade MFA without enterprise-grade pricing.
Plans: Duo Free $0/mo per seat · Duo Essentials $3/mo per seat · Duo Advantage $6/mo per seat · Duo Premier $9/mo per seat
-
Frontegg
IdentityUser management for B2B SaaS.
Frontegg is going after the B2B SaaS builder market — teams that need to ship auth fast without rolling their own. The free tier up to 7,500 MAUs undercuts Auth0's entry pricing and signals they're trying to win developer-led adoption before competitors even get a meeting.
Plans: Pay as you go $0/mo · Enterprise Contact Sales
-
JumpCloud
IdentityOpen directory platform for IT.
À la carte SSO at $11/user/mo puts them in direct competition with Okta and Azure AD, but JumpCloud's pitch is consolidation — replace multiple point solutions with one platform. They're positioning as the scrappy alternative to Microsoft's identity stack for mid-market IT teams who don't want to pay enterprise prices or manage that complexity.
Plans: Platform Essentials Contact Sales · Platform Contact Sales · Platform Prime Contact Sales
-
Kinde
IdentityAuth and billing for modern SaaS.
Kinde is positioning as the developer-friendly Auth0 alternative that doesn't punish you for growing — Auth0 and Okta CIC get expensive fast at scale, and Kinde's entry price is significantly lower. They're going after the startup-to-growth-stage segment that finds Auth0 overkill and Clerk too frontend-focused.
Plans: Free $0/mo · Pro $25/mo · Plus $75/mo · Scale $250/mo
-
Okta
IdentityIdentity and access management.
Okta sits firmly in the premium tier of the IAM/identity space — they're not trying to win on price against tools like JumpCloud or even Azure AD bundled into M365. The custom pricing on Professional and Enterprise signals they're going after mid-market and up, where deal size justifies a sales conversation and price becomes secondary to compliance and integration depth.
Plans: Starter $6/mo per seat · Essentials $17/mo per seat · Professional Contact Sales · Enterprise Contact Sales
-
Stytch
IdentityPasswordless auth infrastructure.
Stytch is positioning as the developer-friendly, modern alternative to Auth0 and Okta — not the cheapest option, but cheaper than enterprise auth incumbents at scale, targeting technical teams who want API-first flexibility without legacy complexity.
Plans: Pay as you go $0/mo · Enterprise Contact Sales
-
SuperTokens
IdentityOpen-source user authentication.
SuperTokens is aggressively undercutting Auth0 and Clerk on price — $0.02/MAU is a fraction of what incumbents charge at scale, and the free self-hosted option directly targets cost-conscious engineering teams who'd otherwise roll their own auth. They're clearly going after the 'why are we paying so much for auth' crowd.
Plans: Self-hosted $0/mo · Cloud $0/mo
