5 best Stytch alternatives in 2026

Stytch works, until your enterprise deals outgrow it. Here's what to use instead.

Stytch built its reputation as a developer-first identity platform with strong passwordless authentication, clean APIs, and a headless architecture that gave engineering teams fine-grained control over the login experience. In October 2025, Twilio announced it was acquiring Stytch, and the deal closed on November 14, 2025. The product continues to operate, but it now sits inside a much larger communications platform with a roadmap centered on unifying identity for humans and AI agents across Twilio's channels.

For B2B SaaS teams, that change raises fair questions. Will the roadmap still prioritize the enterprise SSO, SCIM, and multi-tenant work that closed your last five deals? How will pricing evolve inside Twilio? And do the B2B features you're paying for actually hold up at enterprise scale, or do they start to feel like a thin layer on top of a consumer-first product?

If any of those questions resonate, there are strong alternatives worth a close look. In this article, we compare five of the top Stytch alternatives for B2B SaaS, including what each one does well and where it falls short.

Why should you consider a Stytch alternative?

Here are three reasons B2B teams are re-evaluating Stytch in 2026.

Uncertainty from the Twilio acquisition

Acquisitions are not inherently bad for customers, but they do change the calculus. Twilio has stated that Stytch will keep operating, and the combined company is investing in agent-ready identity. At the same time, Stytch is now one product line inside a much larger CPaaS portfolio, and its priorities will be shaped by Twilio's strategy going forward. The parallel most observers draw is Auth0's acquisition by Okta in 2021, which meaningfully shifted that product's focus and pricing over time. For B2B SaaS teams buying identity infrastructure on a multi-year horizon, vendor independence and roadmap predictability are legitimate factors to weigh.

Per-connection pricing compounds at B2B scale

Stytch's free tier is generous early on with 10,000 MAUs and five SSO or SCIM connections. Beyond the free tier, SSO and SCIM connections are priced per connection per month at rates in line with other per-connection vendors, but without the same volume-discount ladder that lowers the per-connection cost as you scale. Pricing also scales across multiple meters at once, including MAUs, tenants, SSO connections, SCIM connections, and machine-to-machine exchanges. Common B2B needs like custom branding and fraud and risk tools sit on top as paid add-ons. At 50 enterprise customers with both SSO and SCIM, the monthly bill is in the low five figures, which can catch teams off guard as their customer count grows.

B2B depth was built on top of a B2C foundation

This is the most substantive technical reason to evaluate alternatives. Stytch's B2B product was added later on top of a platform originally built for consumer authentication, and the seams show up in a few places that matter for enterprise deals.

Authorization is shallow. Stytch offers tenant-scoped RBAC but does not provide attribute-based authorization, contextual or risk-driven policies, or lifecycle automation out of the box. Session management is constrained: global logout across devices typically requires identifying and revoking sessions one at a time, which adds complexity for enterprise customers who expect clean logout behavior. Legacy identity providers can be difficult to integrate, since Stytch's model is forward-looking and opinionated. And the admin portal is embeddable but basic, which means your engineering team still owns much of the tenant configuration UX your customers' IT admins will interact with.

None of these are blockers on their own. Taken together, they explain why some teams moving upmarket find themselves writing more glue code, not less, as they grow.

Top Stytch alternatives in 2026

1. WorkOS
2. Auth0
3. Descope
4. Keycloak
5. PropelAuth

1. WorkOS

WorkOS is a developer-focused identity platform built to make B2B SaaS apps enterprise-ready quickly. It pairs free user management with enterprise features like SSO, Directory Sync, and audit logs, and ships a polished hosted UI through AuthKit.

Key features

• Flexible UI support via APIs and SDKs, with AuthKit as a highly customizable hosted login powered by Radix.
• Enterprise SSO with native SAML and OIDC, configurable by customers through an Admin Portal.
• SCIM provisioning: Automated user provisioning and deprovisioning that enterprises expect, handling the "remove this employee immediately" requests that inevitably arrive. Real-time synchronization with any identity provider (Okta, Azure AD, Google Workspace, and more).
• Tamper-proof audit logs for SOC 2, HIPAA, and GDPR.
• AI-powered CLI: Run one command, the CLI handles the rest: framework detection, SDK installation, route creation, environment setup, and build validation. Your app goes from zero auth to full AuthKit integration in about two minutes.
• MCP Auth: Built-in authentication for MCP servers and AI agents, with support for delegated access, agent-scoped tokens, and audit trails for agent actions. Lets you ship agent-ready workflows on your existing B2B auth stack instead of bolting on a separate identity layer.
• Passkeys, MFA, social logins, magic auth, and more.
• Secure session handling with server-side validation and instant session revocation capabilities.
• Radar for suspicious login detection and threat monitoring that alerts you to potential account compromises.
• RBAC and Fine-grained authorization: Role-based access control with customizable permissions.
• First-class multi-tenancy with organization management, member invitations, and role assignment.
• On-prem deployment support: Per-environment API keys and firewall-friendly traffic patterns for customers who deploy your SaaS into their own cloud or data center. Useful for closing deals in regulated industries with strict data residency or infrastructure requirements, without forking your auth stack.
• Enterprise SLA and dedicated support.
• Pricing that scales with growth, with $0 for the first 1 million users.

Pricing

• User management: Free for up to 1 million MAUs.
• Single Sign-On: $125 per connection per month, with automatic volume discounts that step down as you scale.
• Directory Sync: $125 per connection per month.
• Audit logs: Starts at $5 per organization per month.
• Custom domains: $99 per month, flat rate.

Best for

B2B SaaS companies that want an independent, developer-friendly platform with enterprise SSO and SCIM as first-class primitives, generous user-management pricing, and volume discounts that lower the per-connection cost as they close more enterprise deals.

Trade-offs

If your app is pure B2C with no enterprise customers on the horizon, WorkOS's enterprise-first primitives may be more than you need today. The upside is that the foundation is already in place the moment your first enterprise deal lands, with no rewrites required.

2. Auth0

Auth0, now part of Okta, is the most established name in authentication. It supports nearly every auth protocol and identity provider, with a mature ecosystem of extensions and integrations.

Key features

• Universal login: A hosted login experience with support for a wide range of authentication methods.
• Extensive IdP support: Works with every major SAML and OIDC identity provider and supports dozens of social logins.
• Actions: Custom JavaScript that runs during the login pipeline for bespoke logic and enrichment.
• Organizations: B2B multi-tenant primitives with SSO connections scoped per organization.
• MFA and passwordless: A broad range of authenticator options, including WebAuthn and passkeys.
• Compliance: SOC 2, HIPAA, ISO 27001, and other certifications available across higher tiers.

Pricing

Auth0 prices by Monthly Active Users, with separate ladders for B2C and B2B. B2B Essentials starts at $150 per month for 500 MAUs with up to three enterprise SSO connections, and Professional starts at $800 per month for 500 MAUs with up to five connections. Pricing can escalate quickly as MAUs grow, and several enterprise features are gated behind higher tiers.

Best for

Teams that want the broadest possible ecosystem and are comfortable paying for it. Less ideal if predictable pricing at scale is a priority, since MAU-based billing combined with feature gating can become unpredictable as usage grows.

Trade-offs

• Pricing unpredictability: MAU-based pricing combined with tier-based feature gating can lead to significant cost increases as user bases grow, and essential enterprise features like SAML SSO, SCIM provisioning, and custom domains are often gated behind higher tiers.
• Vendor independence: Auth0 has been part of Okta since 2021, and the product's priorities now sit within Okta's broader strategy rather than as an independent roadmap.
• Universal Login redirect: The default hosted login flow redirects users away from your app, which can feel heavy-handed compared to embedded auth options.
• Documentation complexity: Extensive docs, but navigating advanced scenarios like custom flows and complex multi-tenant configurations takes more effort than newer alternatives.
• SCIM limitations: Provisioning is supported primarily for specific enterprise connections, with more configuration constraints than purpose-built B2B alternatives.

3. Descope

Descope is the closest philosophical match to Stytch among the alternatives. It is a modern, developer-first CIAM platform focused on passwordless authentication and visual flow orchestration, and it is still independent.

Key features

• Descope Flows: A drag-and-drop visual editor for designing authentication journeys, including sign-up, sign-in, MFA, and step-up flows, without writing custom code.
• Passwordless-first: Magic links, OTP, passkeys, and social login as core primitives.
• SSO and SCIM: SAML and OIDC connections, plus SCIM provisioning on higher tiers.
• Risk and fraud controls: Risk-based MFA, bot protection, and a connector ecosystem for identity verification.
• Agent-ready auth: Primitives for MCP and agent token exchange on paid tiers.

Pricing

• Free: Up to 7,500 MAUs, 10 tenants, and 3 SSO connections.
• Pro: Usage-based overages beyond the free limits, with paid add-ons for bot protection and SCIM.
• Growth: Approximately $799 per month, including 25,000 MAUs, 100 tenants, and 10 SSO connections.
• Enterprise: Custom pricing.

Best for

Teams that like Stytch's developer-first posture but want a visual flow editor and a vendor that is still independent. One caveat worth surfacing: Descope's data model is user-first rather than organization-first, so behaviors that org-first platforms handle natively (per-org domain routing, per-org role assignment, org hierarchy) are achievable through Flow construction rather than as default behavior. That's a tradeoff worth testing against your own B2B requirements before committing.

Trade-offs

• User-first data model: B2B patterns like per-org domain routing, per-org role assignment, and org hierarchy are achievable through Flow construction rather than being default behavior.
• Multi-meter billing: Pricing scales across MAUs, tenants, SSO connections, SCIM connections, and machine-to-machine exchanges simultaneously, which makes costs harder to model at scale.
• Flow editor maintenance: The visual editor is powerful, but flows become a maintenance surface as product requirements evolve, especially in complex B2B scenarios.
• Younger platform: Less battle-tested than Auth0 or Keycloak, with a smaller ecosystem of community resources, third-party integrations, and production deployments.
• SCIM gating: SCIM provisioning is only available on higher tiers.

4. Keycloak

Keycloak is the most established open-source identity and access management platform, maintained by Red Hat. It is a strong pick for teams that want full control over their auth stack and have the operational capacity to run it.

Key features

• Open source and self-hosted: Deploy on your own infrastructure, in a private cloud, or on-prem. No license fees, and no vendor lock-in.
• Broad protocol support: SAML, OpenID Connect, OAuth 2.0, LDAP, and Kerberos.
• Identity brokering: Federate with any SAML or OIDC identity provider, plus social logins and legacy directories like Active Directory.
• Multi-tenancy via realms: Each realm is an isolated identity namespace with its own users, clients, roles, and policies.
• Fine-grained authorization: Role-based and attribute-based access control, with policies defined through the admin console.
• Extensible: Service provider interfaces let you customize authentication flows, user storage, and event listeners.

Pricing

Keycloak is free and open source. Real costs show up in infrastructure, engineering time to configure and maintain the service, and any managed-hosting or enterprise-support contracts you add on top (such as the Red Hat build of Keycloak or third-party managed Keycloak offerings).

Best for

Teams with strong DevOps capability, data residency or air-gap requirements, or a hard preference for open source. Worth flagging that Keycloak's realm-based multi-tenancy was originally designed for workforce IAM isolation, so B2B SaaS patterns like "our customers' organizations" typically take more configuration than in purpose-built B2B platforms. Compliance certifications like SOC 2 and ISO 27001 are also your responsibility to obtain and maintain.

Trade-offs

• Operational burden: You own hosting, scaling, patching, and uptime. Running Keycloak in production is real engineering work, not a drop-in managed service.
• No built-in compliance certifications: SOC 2, ISO 27001, HIPAA, and similar certifications are your responsibility to obtain and maintain on your own infrastructure.
• Basic admin UI: The admin console is functional but significantly less polished than managed alternatives, which shifts more of the tenant configuration UX onto your engineering team.
• Realm-based multi-tenancy: Realms were designed for workforce IAM isolation, so the "our customers' organizations" B2B pattern takes more configuration than in purpose-built B2B platforms.
• Extensions needed for modern features: Passwordless flows, SCIM provisioning, and some other features require community extensions or custom development.
• Steeper learning curve: Configuring realms, clients, identity brokering, and authorization policies takes significant initial investment compared to managed platforms with opinionated defaults.

5. PropelAuth

PropelAuth is a managed B2B-native authentication platform. It was designed from day one around the organizations-and-members model that B2B SaaS apps need, and its pricing model offers a clear philosophical contrast to per-connection vendors.

Key features

• Organizations as first-class primitives: Every user belongs to one or more orgs, and roles, permissions, and SSO are scoped at the org level by default.
• Enterprise SSO: SAML and OIDC support with self-service configuration for your customers' IT admins.
• SCIM provisioning: Available on the higher-tier plan, with group-to-role mapping.
• Hosted UI and components: Drop-in React components for sign-up, login, org management, and user profile, plus a hosted login option.
• MCP auth: Supported as a platform primitive for agent-ready workflows.
• Audit logs and role management: Included in the managed service.

Pricing

• Free: Covers small apps and early-stage B2B use cases.
• Growth: Approximately $150 per month, with unlimited SSO connections included.
• Growth Plus: Approximately $500 per month, adding SCIM and more advanced controls.
• Enterprise: Custom pricing.

Best for

Small to mid-market B2B SaaS teams that want a managed platform with an org-first data model and predictable flat-tier pricing rather than per-connection billing. Less proven at the very top of the enterprise market than WorkOS or Auth0, but a credible managed alternative for teams whose enterprise footprint is still growing.

Trade-offs

• Smaller ecosystem: Less brand recognition, fewer community resources, and a smaller integration catalog than more established platforms.
• Less proven at the top of enterprise: A good fit for mid-market B2B SaaS, but teams closing Fortune 500 deals may find more depth and infrastructure-grade stability in WorkOS or Auth0.
• Hosted only: No self-host option, so data residency, air-gapped deployments, and full data sovereignty are not supported.
• SCIM gating: SCIM provisioning requires the Growth Plus tier and is not available on entry-level plans.

Choosing the right Stytch alternative

The best authentication solution depends on your use case, team size, and growth trajectory:

• Choose WorkOS if you're building a B2B SaaS app that needs to sell to enterprise customers. Free user management up to 1 million MAUs, volume-discounted SSO and SCIM, a hosted admin portal, and first-class multi-tenancy come out of the box.
• Choose Auth0 if you want the broadest ecosystem and the most mature feature set, and you're comfortable with MAU-based pricing that can escalate as you scale.
• Choose Descope if you want Stytch's developer-first posture with a visual flow editor and a vendor that's still independent. Worth testing the user-first data model against your B2B requirements first.
• Choose Keycloak if you have strong DevOps capability and need open source, data residency, or an air-gapped deployment. Expect real engineering investment to configure B2B multi-tenancy and obtain compliance certifications yourself.
• Choose PropelAuth if you want a managed B2B-native platform with org-first primitives and flat-tier pricing that includes unlimited SSO, without going all the way to WorkOS's enterprise scale.

Frequently asked questions

What should I consider when choosing a Stytch alternative?

The key factors for B2B SaaS are how the platform models organizations and tenants, how enterprise SSO and SCIM are priced as your customer count grows, whether the admin UX is polished enough to hand to your customers' IT teams, and how much engineering work it takes to ship a production-ready sign-in flow. Vendor independence and roadmap predictability are also worth weighing given recent consolidation in the space.

Is it difficult to migrate from Stytch to another provider?

Migrating user accounts, passwords, and sessions takes planning. Most alternatives support bulk user import and just-in-time migration, where users are re-authenticated against Stytch on first login and then written into the new system. Password hashes may require a support ticket from Stytch to export. SSO and SCIM connections usually need to be reconfigured per tenant, and your customers' IT admins will need to update their identity provider settings.

Can Stytch alternatives handle enterprise requirements?

Yes. WorkOS, Auth0, and Keycloak all support SAML SSO, SCIM, audit logs, and MFA at enterprise scale. WorkOS is built specifically to make B2B SaaS apps enterprise-ready quickly, with a free user management tier that extends up to 1 million MAUs and volume discounts on SSO and Directory Sync connections.

Are there any open-source Stytch alternatives?

Yes. Keycloak is the most established open-source option, with multi-tenant realms, SAML, OIDC, and fine-grained authorization. Other OSS-first projects worth a look include Ory and SuperTokens.
