Tesseral - 2026 Pricing, Features, Reviews & Alternatives

Tesseral provides a comprehensive B2B user management system that enables businesses to implement enterprise-ready authentication, role management, and API security with minimal code. The platform offers a pre-built login UI that can be customized to match brand styling while supporting various authentication methods including social logins and single sign-on. Tesseral integrates seamlessly with all major identity providers, supporting SAML single sign-on and SCIM programmatic provisioning for streamlined user management across enterprise environments.

The system features fine-grained authorization capabilities that allow organizations to design custom access control policies and offer tailored roles to customers. Managed API keys authenticate API requests and extend API access to customers with custom permission scopes. Tesseral includes advanced security features such as phishing-resistant multi-factor authentication through passkeys, support for authenticator apps, and user impersonation functionality that helps troubleshoot customer issues by allowing administrators to view exactly what customers see in the application.

Tesseral is engineered to work with all major web frameworks including Next.js, React, Flask, Express.js, and Go, providing specialized SDKs to simplify implementation and accelerate development. The platform includes webhook support for real-time updates, ensuring systems remain synchronized with the user management infrastructure. Role-based access control enables organizations to implement permissions checks with minimal code, while the managed API key system issues revocable, tightly-scoped keys for secure API access.

The architecture of Tesseral prioritizes both security and developer experience, making it suitable for organizations at any scale. The platform supports advanced enterprise features such as SCIM provisioning that empowers customers to manage users directly from their identity provider. This comprehensive approach to user management, authentication, and authorization creates a secure foundation for B2B applications while reducing development complexity and implementation time.
