Overview

What it is

A full-stack, open source authentication platform for B2B software. Tesseral eliminates the complexities of authentication, so developers can focus on core product features without compromising on security.

Intent

I need it when

Implement enterprise-grade authentication and user management for B2B SaaS applications

Tesseral provides a complete, multi-tenant auth infrastructure purpose-built for B2B SaaS. It handles user management, login pages, SSO (SAML/OIDC), MFA, and role-based access control without requiring developers to build these features from scratch. The managed service at console.tesseral.com eliminates infrastructure setup.

Enable customers to control their own authentication and user provisioning settings

Tesseral's B2B multitenancy model lets each customer's admins manage their tenant's login methods, user invitations, and authentication policies through self-service configuration pages. Customers can add or remove users and configure SAML/OIDC/SCIM without developer intervention.

Integrate authentication across multiple technology stacks and frameworks

Tesseral is API-first and framework-agnostic, offering SDKs for Next.js, React, Express, Python (Flask/FastAPI/Django), Golang, and Rust (Axum). It works with any tech stack via REST APIs, allowing teams to use their preferred languages and frameworks.

Add enterprise SSO and directory sync capabilities to a SaaS product

Tesseral bundles SAML, OIDC, and SCIM support as pre-built features. Developers can enable enterprise single sign-on and directory synchronization with just configuration clicks in the Tesseral Console, without writing authentication code.

Debug user issues and provide customer support by viewing the application from a user's perspective

Tesseral includes user impersonation functionality that lets support teams log in as specific users to see exactly what they see, enabling faster debugging and better customer support without requiring users to share credentials.

Drop

Not a fit when

  • When you need a lightweight authentication library tightly coupled to a specific programming language or framework
  • When you require on-premises deployment with no cloud infrastructure available
  • When your application serves consumer (B2C) users rather than business (B2B) customers
  • When you need authentication without multi-tenant organization support
  • When you cannot use a third-party SaaS provider and must build authentication entirely in-house
