You can integrate ZITADEL quickly into your application and be up and running within minutes. To achieve your goals as fast as possible, we provide you with SDKs, Example Repositories and Guides.

The SDKs and integration depend on the framework and language you are using.


To further streamline your setup, simply visit the console in ZITADEL where you can select one of the languages or frameworks. This will allow you to instantly set up the configuration for that specific sample in ZITADEL, ensuring you have everything you need to get started right away.


To begin configuring login for any of these samples, start here.

OIDC Libraries

OIDC is a standard for authentication and most languages and frameworks do provide a OIDC library which can be easily integrated to your application. If we do not provide an specific example, SDK or guide, we strongly recommend using existing authentication libraries for your language or framework instead of building your own. Certified libraries have undergone rigorous testing and validation to ensure high security and reliability. There are many recommended libraries available, this saves time and ensures that users' data is well-protected.

Missing SDK

Is your language/framework missing? Fear not, you can generate your gRPC API Client with ease.

  1. Make sure to install buf
  2. Create a buf.gen.yaml and configure the plugins you need
  3. Run buf generate,tag=v2.23.1 (change the versions to your needs)

Let us make an example with Ruby. Any other supported language by buf will work as well. Consult the buf plugin registry for more ideas.

Example with Ruby

With gRPC we usually need to generate the client stub and the messages/types. This is why we need two plugins. The plugin grpc/ruby generates the client stub and the plugin protocolbuffers/ruby takes care of the messages/types.

version: v1
- plugin:
out: gen
- plugin:
out: gen

If you now run buf generate,tag=v2.23.1 in the folder where your buf.gen.yaml is located you should see the folder gen appear.

If you run ls -la gen/zitadel/ you should see something like this:

ffo@ffo-pc:~/git/zitadel/ruby$ ls -la gen/zitadel/
