Identity architecture for B2B + AI systems

B2B AI demands org-scoped identity, delegated authority, hardened sessions, 
across users, agents, and services
Organizations define identity. Users inherit context
In B2B, access is not tied to a user alone. It is defined by which organization they belong to and what role they hold there. If org and membership are not first-class, isolation becomes accidental
Authentication must be tenant-scoped
Each organization defines how its users authenticate. SSO, allowed domains, passwordless, MFA. Configured per tenant, not enforced globally
Session needs to be hardened by default
Sessions must explicitly bind the active org and authority to prevent cross-tenant access. HTTPS-only cookies are a must to protect your app from client-side access
B2B identity now includes agents and services
Agents, integrations, and services act inside your system.
Identity must extend beyond users to cover all end points. If your model stops at human login, your architecture stops there too

Turn identity architecture into operational control

Enterprise onboarding, signup enforcement, delegated access, and tenant-aware audit logs, built directly into your auth layer
Go to Scalekit docs

Unify identity layers for users, MCPs, and agents

Clerk covers user login only. Scalekit extends identity to secure MCP authentication and delegated access for agents:
Handle tenant-aware inbound auth for users and MCP clients
Enable agents to act on behalf of users with scoped authority
Embed org, role, and membership context in every token
Enforce consistent policy across humans, machines, and agents

Offload enterprise onboarding with Admin Portal

Without a built-in Admin Portal, Clerk pushes SSO and SCIM setup to your dev team. There is no native, SCIM support.
Scalekit’s enterprise auth modules:
Support both SSO and SCIM without custom development
Let IT configure connections in the Admin Portal
Support all major SSO IdPs and SCIM directories
Ship a fully branded Admin Portal, embedded or hosted

Enforce policy inside the auth flow

Clerk relies on event hooks after authentication. Scalekit enforces tenant policy directly within the authentication flow:
Intercept signup and login before sessions are created
Evaluate tenant rules and domain restrictions synchronously
Block or approve access in real time
Enforce org policy across users, agents, and M2M tokens

Make audit logs tenant-aware and enforceable

Clerk provides event-based logs. But in B2B systems, debugging requires full tenant context in every payload. Scalekit provides:
Full event payloads with org, role, and membership context
IP, device, and auth method captured per request
Deterministic request tracing across tenants
Per-tenant log export for SIEM and compliance workflows

Make authorization part of the identity layer

Clerk leaves most access modeling to your application code. Scalekit makes roles and permissions first-class.

Powering identity for modern B2B AI platforms

It's the most simple and easily understandable platform we could find for Auth. It's free to get started and they have the best customer support I have experienced when compared to some of their major competitors.
Emil Sarkisi Stepanian
Founder / Hubbl
Every question we had was answered in hours, not days. It saved us weeks of troubleshooting and let us stay focused on delivery.
Gábor Szabad
Engineering Lead
Scalekit’s documentation is thorough and easy to follow, and their support is proactive. The pricing is transparent, which makes budgeting and forecasting much simpler compared to other solutions like Auth0 and WorkOS.
Mac Gainor
CTO
Scalekit's flexibility and speed made implementation a breeze. We got secure, scalable, passwordless auth and have the option to open up other methods like SSO as we see fit, without having to refactor the existing stack.
Suman Varanasi
CTO
We didn’t want to build authentication in-house. Scalekit allowed us to implement production-ready flows with minimal dev effort. The impact has been faster deployments and a much better experience for our devs and users.
Himavanth Jasti
Co-founder, Tech
We needed an auth solution that just works so we could focus on our core AI features. Scalekit eliminated months of auth complexity and let us ship it in weeks
Harsh Vakharia
CTO
Scalekit turned what could’ve been months of heavy lifting into a smooth rollout. It helped us focus on core features while still delivering a secure, enterprise-ready solution.

Why developers consistently choose
Scalekit over Clerk

Go to docs
Org-native APIs
Build with APIs and SDKs designed around orgs, users, and roles, not low-level primitives
Auth interceptors
Apply security and business rules during signup, login, and token issuance
Webhooks
Receive auth and lifecycle events without building custom pipelines
Abstractions
Reduce edge cases, cut glue code, and iterate faster as you scale to enterprise

Pay for organizations, not authentication events

Clerk’s user-first approach makes pricing scale with sessions and seats. Scalekit aligns pricing with organizations and enterprise identity needs.
