Tilt
What it is
Tilt is a free, open-source development environment for teams building microservices, particularly teams deploying to Kubernetes. It watches files, builds container images, and updates the development environment as code changes. Its live_update feature sends code changes to running containers in seconds, including changes involving compiled languages or dependencies. Tilt can start an application and automate rebuilds, bringing logs, failed builds, and runtime errors into the development feedback loop. Its UI gathers service logs and shows development environment state. Teams configure services and workflows with Tiltfiles using Kubernetes YAML and Docker images; the documentation also describes integrating Bazel builds. Tilt works with Docker and Kubernetes and can support workflows involving Helm, Podman, or local processes. It runs on macOS, Linux, and Windows, with editor support for VS Code, selected JetBrains IDEs, and other editors through an embedded language server. The standard installation requires Docker, kubectl, and a local Kubernetes cluster. Tilt is maintained as open source by Docker, Inc. under the Apache-2.0 license.
For and against
For
- Watches files and updates the development environment.
- Live updates deploy code to running containers.
- The UI gathers logs and development environment status.
- Extensions can share Tiltfile functionality, including team scripts.
Against
- Standard setup requires Docker, kubectl, and a local Kubernetes cluster.
- Tilt prompts users to choose whether to share anonymized analytics.
- Hashed telemetry strings may still contain project snippets.
The verdict
Tilt brings rebuilds, runtime feedback, and service logs into a shared development workflow. Teams should weigh its standard setup requirements and telemetry details before adopting it.
Who it suits
Tilt is for teams developing microservice applications and coordinating services such as databases, frontends, and web apps. Its standard setup suits teams with Docker, kubectl, and a local Kubernetes cluster.
