--- ko_meta: true --- # Introduction `ko` makes building Go container images easy, fast, and secure by default. ![Demo of ko build](./images/demo.png) `ko` is a simple, fast container image builder for Go applications. It's ideal for use cases where your image contains a single Go application without many dependencies on the OS base image (e.g., no cgo, no OS package dependencies). `ko` builds images by executing `go build` on your local machine, and as such doesn't require `docker` to be installed. This can make it a good fit for lightweight CI/CD use cases. `ko` makes [multi-platform builds](https://ko.build/features/multi-platform/) easy, produces [SBOMs](https://ko.build/features/sboms/) by default, and includes support for simple YAML templating which makes it a powerful tool for [Kubernetes applications](https://ko.build/features/k8s/). --- > 🏃 [Install `ko`](./install) and [get started](./get-started)! --- `ko` is used and loved by these open source projects: - [Knative](https://knative.dev) - [Tekton](https://tekton.dev) - [Karpenter](https://karpenter.sh) - [Kyverno](https://kyverno.io) - [Sigstore](https://sigstore.dev) - [Shipwright](https://shipwright.io) - [Capsule](https://capsule.clastix.io/) - [CloudScript](https://cloudscript.com.br/) - [Kamaji](https://kamaji.clastix.io/) [_Add your project here!_](https://github.com/ko-build/ko/edit/main/docs/index.md) --- `ko` is a Cloud Native Computing Foundation Sandbox project.
