What you can do

• One service.json per service. Flisk generates the Dockerfile, the Compose entry, the Traefik routes, the health check and the Tiltfile from it. You do not hand-write a docker-compose.yml or nginx.conf.
• One command, one address. flisk up starts Postgres, your services and a local gateway, starts services in health-checked dependsOn order, and prints a *.localhost URL for each.
• Hot reload while you code. Tilt live-updates a container when you save its files; there is no rebuild step.
• Wired for you. DATABASE_URL, the API URL your frontend calls, and missing secrets such as JWT_SECRET are generated and injected, never copied by hand.
