Manage licenses

Free access

You don’t need a license to access the Community version of Conduktor. The Community plan allows you to manage and monitor any number of Kafka clusters but provides only limited access to powerful Conduktor features.

The unlicensed Conduktor Gateway version has a 14-day trial and will stop working when that period ends. Contact us to extend your trial or find out about licensing options.

Apply your license

We recommend applying your license to the environment variables. Alternatively, you can add it to your YAML config file.

Use Console

Environment variables

.env

CDK_LICENSE='YOUR_LICENSE_HERE'

YAML file

platform-config.yaml

license: 'YOUR_LICENSE_HERE'

Verify your license

Use Console to check that your license has been applied correctly. You can do this via the UI or by checking the logs.

Use the UI

Log into Conduktor Console then go to Settings > Plan:

Use the logs

Run Console then check the logs in the head: License Enterprise is valid until 2026-01-01 00:00:00.

Versions before 1.21

Input configured license : Some("YOUR_LICENSE_HERE") License is valid ! Remaining days : 365

Renew or update your license

To renew an existing or apply a new license, change the CDK_LICENSE value in the environment variables (or the license value in the YAML file, depending on your setup) and re-deploy the Conduktor Console container.

Use Gateway

The license we provide to you has to be set as an environment variable in your Gateway configuration:

.env

GATEWAY_LICENSE_KEY="YOUR_LICENSE_HERE"

Verify your license

You can check that your license has been used to launch the Gateway by looking at the license internal topic it has created.

The default name of this topic is _conduktor_gateway_license, but it might be different if:

• You have set another name via GATEWAY_LICENSE_TOPIC
• You have set the GATEWAY_CLUSTER_ID, then the topic will be _conduktor_${GATEWAY_CLUSTER_ID}_license.

In this topic, you'll find the license expiration date.

Enterprise plan

{
  "io.conduktor.proxy.avro.schema.AvroLicense.ConduktorLicense": {
    "token": "YOUR_LICENSE_HERE"
  }
}

Free plan

{
  "io.conduktor.proxy.avro.schema.AvroLicense.FreeLicense": {
    "expirationDate": "1730280320532"
  }
}

And you can find the details of the license in the Gateway logs:

2025-05-20T14:38:09.961+0000 [main] [INFO] [PersistentLicenseService:94] - Applied new license with expiry: 2026-01-01T00:00:00.000Z

Renew or update your license

To change your license, change the GATEWAY_LICENSE_KEY environment variable and deploy the Conduktor Gateway container again.
