Launch YC: Tesseral: the open source auth infrastructure for B2B SaaS

"Designed for developers, engineered for security"

TL;DR: Everything you need to manage users in business software, from a login page to session management to SSO and RBAC.

Founded by Ned O'Leary & Ulysse Carion

Tesseral is open source auth infrastructure for business software. You can use it to authenticate your users, and manage their access to resources.

It’s similar to products like Auth0, but it’s open source and built specifically for B2B apps.

It comes with enterprise features like single sign-on, directory provisioning, user impersonation, and multi-factor authentication, as well as beautiful login pages and self-service settings for customers.
