What is KEDA used for?

KEDA is a Kubernetes-based Event Driven Autoscaler that scales containers based on event processing needs. It is a good fit for scaling event-driven applications in Kubernetes, and optimizing workload scheduling and reducing environmental impact.

Yes. KEDA is open source under the Apache-2.0 licence. Its source code is on GitHub at kedacore/keda and is written mainly in Go.

Yes. KEDA is open source, so the software itself is free to use.

Can I self-host KEDA?

Yes. KEDA can be self-hosted on your own server or infrastructure.

What is KEDA an alternative to?

KEDA is an open-source alternative to Azure Container Apps. Other open-source alternatives to Azure Container Apps include Sealos, Rainbond and OpenFaaS.

Is KEDA actively maintained?

Yes. The most recent commit to KEDA was on 13 October 2026, and the latest release is v2.21.0, published on 23 September 2026. The project has 11k stars on GitHub.

KEDA: open-source alternative to Azure Container Apps

About KEDA

KEDA is a Kubernetes-based Event Driven Autoscaler that drives the scaling of any container in Kubernetes based on the number of events needing to be processed. It is a single-purpose, lightweight component that can be added into any Kubernetes cluster.

KEDA works alongside standard Kubernetes components like the Horizontal Pod Autoscaler and extends functionality without overwriting or duplication. It allows explicit mapping of apps for event-driven scale while other apps continue to function, making it a flexible option for various Kubernetes applications.
