## What it is
Tilt is a CLI tool that defines your microservice development environment as code (via a Tiltfile) and automates the loop from code change to running process on Kubernetes. It watches files, builds container images, deploys with kubectl, and provides smart rebuilds and live updates with a terminal UI.

## Use cases
- run a multi-service kubernetes dev environment with one command
- automate docker build and kubectl apply on every code change
- live update code in running kubernetes containers
- define local dev environment as code for a team
- develop microservices locally against a kubernetes cluster
- replace manual docker-compose/kubectl workflows with smart rebuilds

## When to choose
- you develop microservice apps deployed on Kubernetes and want fast inner-loop feedback
- your team wants a shared, versioned dev environment definition
- you want automatic rebuilds and live updates across many services

## When to avoid
- your app is a single service or doesn't use Kubernetes
- you only need production deployment tooling rather than local dev workflow
- you want a fully GUI-based non-CLI workflow
