kind vs Tilt

kind runs local Kubernetes clusters with Docker container nodes, mainly for Kubernetes testing; local development and CI are also listed uses. It bootstraps cluster nodes with kubeadm and supports multi-node setups, including high availability. A configuration file can define worker and control-plane nodes, port mappings, and Kubernetes versions.

The tool can build Kubernetes release builds from source or use pre-published builds. It can detect Docker, Podman, or nerdctl as its container provider, including rootless providers subject to host and provider requirements. Users can load Docker images or an image archive into a cluster. Documentation covers ingress and Gateway API configuration with cloud-provider-kind, private registry workflows, and Kubernetes API audit logging.

Tilt is a free, open-source development environment for teams building microservice applications that deploy to Kubernetes. It watches files, builds container images and updates the development environment when code changes. Its live_update feature deploys changes to running containers in seconds, including compiled-language code or dependency changes. Tilt can start the application and automate rebuilds, with logs, broken builds and runtime errors in its feedback loop. Its UI collects service logs and shows the development environment's state.

Teams configure services and workflows with Tiltfiles using Kubernetes YAML and Docker images; documentation also describes integrating Bazel builds. Tilt has an extension system for sharing Tiltfile functionality, such as team scripts and custom buttons, and provides editor support for VS Code, selected JetBrains IDEs and other editors through an embedded language server. It runs on macOS, Linux and Windows. The standard setup requires Docker, kubectl and a local Kubernetes cluster, though workflows can also use options such as Helm, Podman or local processes. Tilt is maintained as open source by Docker, Inc. under the Apache-2.0 license and costs nothing.
