Components in Confluent Platform use a mix of Apache 2.0, Confluent Community License, and an enterprise license.
A developer license allows full use of Confluent Platform features free of charge for an indefinite duration. However, the license is limited to a single broker configuration per cluster. The developer license gives developers the freedom to try the Confluent Platform commercial features available in a non-production setting.
A trial (evaluation) license allows a free trial of commercial features in a production setting, and expires after 30 days.
For full details of the licenses and which components use which license, please refer to the documentation.
New signups to Confluent Cloud receive $400 to spend within during their first 30 days.

Other components of Confluent require an enterprise license. They can be used under a 30-day trial, or indefinitely under the developer license, when used with a single broker cluster in a non-production setting.
For full details of the licenses and terms please see the documentation.
