The overcast binary: the three commands most people need, and a page per command group — running the daemon, checking it, state, AWS tools, Docker networks, .local hostnames and TLS.

overcast is the emulator daemon and the host-side tooling around it. overcastd, the slim binary, has the same subcommands without the web console.

overcast serve            # run the emulator in the foreground
eval "$(overcast env)"    # point every AWS tool in this shell at it
overcast status           # check it is up, and see what it is running

Every command takes --endpoint (default http://localhost:4566), overcast --version prints the build, and overcast <command> --help prints that command’s flags.
