TL;DR

Tilt is a development orchestrator for Kubernetes/Docker stacks: a Tiltfile declares your builds, manifests, and local commands, and Tilt watches the filesystem to keep the cluster in sync in seconds via live update instead of full image rebuilds. It collapses the "edit → build → push → rollout → wait" loop that makes multi-service local development miserable.
