is-up

checks if websites are accessible

TLDR

Check if site is up

$ is-up [example.com]

Use the exit code in a script (0 = up, 2 = down)

$ is-up [example.com] && echo "online"

is-up checks whether a website is up or down, printing Up or Down. Instead of connecting to the site directly, it queries the third-party isitup.org API, so the check is performed from an external location rather than your own network.It exits with code 0 if the site is up, 2 if it is down, and 1 on usage errors, making it usable in scripts. It is installed from npm as is-up-cli.

PARAMETERS

URL

Website URL or domain to check. A missing http:// scheme is added automatically.

--help

Display help information.

--version

Display version information.

CAVEATS

Only the first URL argument is checked. Results depend entirely on the availability of the isitup.org service, which has been unreliable and returned errors when last checked; if it is unreachable the command fails. Only the hostname is checked, not the specific path. The project has not been updated since 2022.

HISTORY

is-up-cli was created by Sindre Sorhus as a thin command-line wrapper around his is-up Node.js module.
