Let's add users to your apps.

ZITADEL gives developers all they need to integrate identity management. Easy as pie. Ready when you are — because serverless. At yours or ours — because open source.

What we do

Identity management that works for you

You want auth that's quickly set up like Auth0 but open source like Keycloak? Look no further — ZITADEL combines the ease of Auth0 and the versatility of Keycloak.

It is built for devs. And for the serverless age. Featuring multi-tenancy, open source and the cloud. You can get started in minutes on our public cloud service, run it locally or self-host. But mostly: Take care of your business, because your login is taken care of.

What we offer

OpenSaaS: The best of two worlds

Open source and SaaS got together to bring you simplicity while enabling you to dive as deep as you like. The serverless architecture enables you to jump right in and scale up as needed. If you'd rather run your own instance on your computer, that's just one command away.

Open Source image

Open Source

Run your own instance locally. Or wherever you like. And for the ones who think a repo says more than words: No need to ask for keys.

SaaS image


Use our public cloud service (our free plan includes all features) or self-host for full control — in any case, we're happy to lend a hand.
