A CLI utility that automatically synchronizes a local source tree of Plesk or a Plesk extension with a remote machine.
Installation using Homebrew:
brew install plesk/psync/psync
If you have the Go toolchain installed, you can use the following command to install psync:
go install github.com/plesk/psync@latest
The utility uploads files over ssh/scp in non-interactive mode, so it cannot ask for a password. Access to the remote host must be configured with SSH keys:
ssh-keygen -t ed25519 # if you do not have a key yet
ssh-copy-id root@10.66.1.1
On startup, psync verifies that the remote host is reachable without a password prompt and exits with an error if SSH key-based authentication is not set up.
Basic usage:
cd ~/projects/plesk/extensions/ext-broadcast-message
REMOTE_HOST=10.66.1.1 psync
The output looks like the following:
2026/08/12 11:02:26 Plesk extension broadcast-message detected
2026/08/12 11:02:26 watcher is ready...
...
2026/08/12 11:07:52 updated 10.66.95.33:/usr/local/psa/admin/plib/modules/broadcast-message/hooks/ContentInclude.php
...
The utility watches the specified directory and sends the changed files to the specified remote host. Files deleted or renamed locally are removed from the remote host as well.
By default, the current directory is monitored. Use the -c (--chdir) flag to monitor another directory without changing into it:
REMOTE_HOST=10.66.1.1 psync -c ~/projects/plesk/extensions/ext-broadcast-message
To upload the files that are currently changed according to git status (without starting the watcher):
REMOTE_HOST=10.66.1.1 psync diff
Deleted files are removed from the remote host as well. For renamed files, the new path is uploaded and the old one is removed.
The REMOTE_HOST variable can also be stored in a .env file in the monitored directory. The value must not contain spaces; use a user@host form (for example, REMOTE_HOST=root@10.66.1.1) or a host alias from your SSH config.
- The utility runs only on macOS.
- The only supported remote platform is Linux.
