Manage user identities securely with customizable authentication, SSO, MFA, and RBAC. Offers easy APIs, programmable workflows, and multi-tenancy for developers.
European security & identity alternative based in Switzerland.
ZITADEL is an open-source identity infrastructure platform that combines the flexibility of self-hosting with the convenience of a managed cloud — bridging enterprise authentication and developer-friendly APIs in a single product.
The platform handles the full identity lifecycle: login pages, social logins, SSO, MFA, passkeys, RBAC, machine identities, and multi-tenancy — all configurable through gRPC and REST APIs. ZITADEL Actions let teams run custom workflows after any auth event without writing a custom server.
Key features:
- Authentication — hosted login UI, social logins, passkeys, MFA, and SSO
- Authorization — role-based access control with fine-grained permission management
- Multi-tenancy — add new organisations, delegate admin rights, and isolate data per tenant
- Machine identities — service accounts and API key management for non-human actors
- Extensible — ZITADEL Actions execute serverside logic after any auth event
- APIs — modern gRPC and REST, with SDKs for Go, Angular, React, Next.js, Flutter, and Python
- Compliance — OpenID certified, ISO 27001, GDPR, and SOC 2 Type II
Open source with 4,000+ GitHub stars and 50+ contributors. Deploy to your own infrastructure or use ZITADEL Cloud with EU data residency.
