Clerk alternatives for B2B SaaS, with the org-support angle.
Clerk is the default for developer-friendly authentication, but B2B SaaS has different requirements: organizations, tenant isolation, invite flows, SAML, and role-based access. Here is how Kinde, Stytch, and PropelAuth compare when your buyers are teams, not consumers. Pricing checked June 2026.
The B2B auth checklist
Consumer auth is about signup and login. B2B auth is about who owns the account, who can invite whom, and how tenants stay separate. Before picking a Clerk alternative, confirm it handles:
- Organization / workspace creation
- Member invites and role assignment
- Tenant-scoped sessions and permissions
- SAML / SSO for enterprise customers
- Admin impersonation for support
- Usage-based or predictable billing
Pricing and B2B feature comparison
| Tool | Pricing | B2B multi-tenancy | Best for |
|---|---|---|---|
| Clerk | Free up to 10k MAU · Pro $25/mo | Yes — orgs, roles, invitations | Teams that want drop-in auth UI and fastest time-to-market. |
| Kinde | Free up to 10k MAU · Pro $25/mo | Yes — orgs + policies + feature flags | SaaS founders who want Clerk-like DX with B2B primitives built in. |
| Stytch | Free tier · B2B plan from ~$99/mo | Yes — via B2B authentication product | Engineering teams building custom auth flows or passwordless experiences. |
| PropelAuth | $0 · Growth $49/mo + usage | Yes — orgs, roles, SAML, SCIM | B2B SaaS that want predictable bills and dedicated B2B support. |
Clerk
Organizations and roles ship on Pro, but advanced B2B features (SAML, RBAC, impersonation) move to Enterprise.
Kinde
Native multi-tenancy, organizations, and fine-grained permissions are core product pillars, not add-ons.
Stytch
API-first, passwordless-first. B2B auth (organizations, SSO, SCIM) is a dedicated product line.
PropelAuth
Flat monthly base + per-MAU overages. Explicitly built for B2B SaaS with organizations and SAML.
Who should switch from Clerk
- ✓You need organization management, invites, and roles as core features.
- ✓You want SAML/SSO without immediately jumping to an Enterprise plan.
- ✓You are selling to teams and want predictable auth pricing as you scale seats.
- ✓You need dedicated B2B support or engineering-led onboarding.
Who should stay with Clerk
- ·You are building a consumer app or simple SaaS with only individual accounts.
- ·Your team values Clerk's pre-built components and dashboard polish.
- ·You already rely on Clerk Webhooks, Sessions, and User objects across your stack.
- ·You have an Enterprise deal that includes SAML, RBAC, and impersonation.
Savings math at 5,000 MAU
- Clerk Pro: ~$25/mo base + overages beyond 10k MAU.
- Kinde Pro: Comparable free/pro tiers; B2B features rarely force Enterprise.
- PropelAuth Growth: ~$49/mo flat base + per-MAU; often cheaper than Clerk Enterprise at the same B2B feature set.
- Stytch B2B: Usage-based; competitive if most users log in infrequently or via passwordless.
The real savings are not always monthly cost — they are avoiding an Enterprise tier just to unlock organizations, SAML, and support. For an early B2B SaaS, that can be a $10k–$30k annual decision.
Caveats
- !Migration is non-trivial: you will need to map Clerk users and sessions to the new provider.
- !Pre-built UI components vary. Kinde is closest to Clerk's drop-in experience; Stytch is more headless.
- !SAML and SCIM connectors are sometimes add-ons everywhere — compare the full enterprise quote, not just list price.
- !Support quality matters more in B2B. A provider with live engineering support can unblock an enterprise deal.
Final verdict
For most B2B SaaS teams outgrowing Clerk's consumer roots, Kinde is the closest drop-in swap with organizations and permissions built in. Choose PropelAuth if you want flat, predictable pricing and a team that specializes in B2B auth. Choose Stytchif you are building custom flows or want a passwordless-first architecture. Stay on Clerk if your app is still consumer-first and its components save you measurable engineering time.
Migration notes
All four providers support exporting user data and importing via CSV or API. The hard part is usually session handling: plan a forced logout and re-auth window, or run both providers in parallel during a transition phase. Budget one to two engineering sprints for a full migration, depending on how deeply Clerk webhooks and sessions are woven into your app.
