To start using Redpanda Serverless, sign up for a free trial. Each trial supports five Serverless clusters. To continue after the trial expires, you can enter a credit card and pay as you go.

Serverless is currently in a limited availability (LA) release with usage limits and no public SLA. During LA, existing clusters can scale to the usage limits, but new clusters may need to wait for availability.


  1. Sign up for a trial of Redpanda Serverless.

  2. Make sure you have the latest version of rpk. See Install rpk.


Each Serverless cluster has the following limits:

  • Ingress: up to 10 MBps, 0.5 MBps guaranteed

  • Egress: up to 30 MBps, 1.5 MBps guaranteed

  • Partitions: 100 logical partitions

  • Message size: 20 MB

  • Retention: unlimited time

  • Storage: unlimited

  • Users: 30

  • ACLs: 120

  • Consumer groups: 200

These baseline limits are subject to change. To increase your limits, contact support.

Trial credits

New trials receive $100 (USD) in free credits to spend in the first 14 days. This should be enough to run Redpanda with reasonable throughput. No credit card is required. To continue using Serverless after your trial expires, you can enter a credit card and pay as you go. Any remaining credit balance is used before you are charged.

When either the 100 credits expire or the 14 days in the trial expire, the clusters move into a suspended state, and you won’t be able to access your data in either the Redpanda Cloud UI or with the Kafka API. There is a 7 day grace period following the end of the trial. After that, the data is permanently deleted.

Get started

After you click to start a trial, Redpanda instantly prepares an account for you. Your account includes a welcome cluster with a hello-world demo topic you can explore. The hello-world topic starts as a free read-only topic. It is materialized and becomes billable with your credits if you produce messages to it.

Interact with your cluster

Similar to Dedicated and BYOC clusters, you can interact with your Serverless cluster with rpk CLI commands or with the Redpanda Cloud UI. For example, you can run rpk topic consume hello-world to read the messages in that topic explaining the rpk steps to stream data. Here are some helpful rpk commands:

  • rpk cloud login: Use this to log in to Redpanda Cloud or to refresh the session.

  • rpk topic: Use this to manage topics, produce data, and consume data.

  • rpk profile print: Use this to view your rpk configuration and see the URL for your Serverless cluster.

  • rpk security user: Use this to manage users and permissions.

Alternatively, in the Redpanda Cloud UI, you can navigate to the Topics page and open the hello-world topic to see the included messages. Under the Actions dropdown, you can produce messages to it. Add team members and grant them access with ACLs on the Security page.

Redpanda Serverless is opinionated about Kafka configurations. For example, automatic topic creation is disabled. Some systems expect the Kafka service to automatically create topics when a message is produced to a topic that doesn’t exist. Create topics on the Topics page or with rpk topic create.

Run a demo application

Run rpk generate app to generate a sample application to connect with Redpanda.

The Redpanda Cloud Overview page lists your bootstrap server URL and security settings in the How to connect - Kafka API tab. In the same section, you can click Go, Python, or Node.js for code examples to create a topic and produce and consume messages.

Create a new cluster

Click the default resource group in the breadcrumbs to return to the Clusters page and create a new Serverless cluster.

Serverless clusters are currently available in certain AWS regions. Redpanda expects your applications to be deployed in the same AWS region. For best performance, select the region closest to your applications. Serverless is not guaranteed to be pinned to a particular availability zone within that region.

Supported features

Serverless clusters work with all Kafka clients. For more information, see Kafka Compatibility.

Serverless clusters support all major Apache Kafka messages for managing topics, producing/consuming data (including transactions), managing groups, managing offsets, and managing ACLs. (User management is available in the Redpanda Cloud UI or with rpk security acl.)

Unsupported features

Redpanda Serverless supports the Kafka API. The Redpanda Admin, HTTP Proxy, and Schema Registry APIs are not exposed. You can use an external schema registry.

The following features are not yet supported in Serverless clusters:

  • Managed connectors

  • Data transforms
