# ZITADEL

> ZITADEL is an open-source identity and access management platform that gives developers enterprise-grade authentication and authorization without vendor lock-in. Built in Go with an API-first design and native multi-tenancy, it supports OAuth2, OpenID Connect, SAML, SCIM, passkeys, MFA and self-service flows, and can run as a self-hosted deployment or as a managed cloud service. Founded in Switzerland in 2019 and now remote-first, ZITADEL aims to make identity a foundational piece of infrastructure - like a database or a web server - rather than a barrier to shipping software.
