Identify Plesk Version & License Type from the Command Line (Linux & Windows)

Quick cheatsheet to identify your Plesk version and license edition from the terminal on Ubuntu and AlmaLinux (and Windows), with copy‑paste commands and one‑liners.

If you manage Plesk servers, there are two things you’re constantly asked for: What version is installed? and Which license/edition is this server running? Here’s a fast, copy‑paste friendly guide for Linux and Windows.

TL;DR

Version: plesk version
Full license details: plesk bin keyinfo --list
Edition (by domain limit):
- 10 domains → Web Admin Edition
- 30 domains → Web Pro Edition
- Unlimited → Web Host Edition

Prerequisites

SSH or console access on Linux; RDP or local access on Windows.
Run commands as root/administrator (or with sudo).

Ubuntu vs. AlmaLinux — What’s Different?

Most commands are identical across modern Ubuntu (20.04/22.04/24.04) and AlmaLinux/Rocky/CentOS Stream (8/9). The key differences are the package manager and a couple of optional verification commands.

Task	Ubuntu	AlmaLinux / Rocky
Show panel version	`plesk version`	`plesk version`
Panel binary path	`/usr/sbin/plesk`	`/usr/sbin/plesk`
Package query (Plesk core)	`dpkg -s plesk-core \| grep -i '^Version'`	`rpm -q psa`
Check installer version	`plesk installer --version`	`plesk installer --version`
System service check*	`systemctl status psa`	`systemctl status psa`
License registry fallback	`/etc/sw/keys/registry.xml`	`/etc/sw/keys/registry.xml`

*Service checks aren’t required to read version/license, but they’re useful when Plesk isn’t responding.

Tip: If plesk isn’t in your PATH, call it with the absolute path: /usr/sbin/plesk.

Check the Plesk Version

Linux

# Standard
plesk version

# Absolute path (if $PATH isn’t set)
/usr/sbin/plesk version

# Standard

plesk version

# Absolute path (if $PATH isn’t set)

/usr/sbin/plesk version

Typical output:

Product version: Plesk Obsidian 18.0.58
Build date:      2025/09/17
OS version:      Ubuntu 22.04 x86_64

Product version: Plesk Obsidian 18.0.58

Build date: 2025/09/17

OS version: Ubuntu 22.04 x86_64

Windows (PowerShell or CMD)

"%plesk_bin%\plesk.exe" version

1 2	"%plesk_bin%\plesk.exe" version

Bonus checks (optional):

# Installer version (not the same as the control panel version)
plesk installer --version

# Package versions
# RPM (CentOS/Rocky/Alma)
rpm -q psa

# DEB (Debian/Ubuntu)
dpkg -s plesk-core | grep -i '^Version'

# Installer version (not the same as the control panel version)

plesk installer --version

# Package versions

# RPM (CentOS/Rocky/Alma)

rpm -q psa

# DEB (Debian/Ubuntu)

dpkg -s plesk-core | grep -i '^Version'

Check License Details & Identify Edition

Linux

# Dump all installed license properties
plesk bin keyinfo --list
# (alias)
plesk bin keyinfo -l

# Dump all installed license properties

plesk bin keyinfo --list

# (alias)

plesk bin keyinfo -l

Look for fields such as key ID, expiration, add‑ons, and limits (e.g., domains, mailboxes, resellers).

Windows

plesk bin\keyinfo.exe --list

1 2	plesk bin\keyinfo.exe --list

Map License Limits to Edition

If the explicit edition name isn’t obvious in the output, use the domain limit as a proxy:

10 domains → Web Admin Edition
30 domains → Web Pro Edition
Unlimited → Web Host Edition

Note: Providers sometimes bundle add‑ons or custom SKUs. If your output differs, the domain limit still reliably indicates the base edition.

Handy One‑Liners (Linux)

# Show edition-ish hints (name/edition/domain limit lines)
plesk bin keyinfo -l | egrep -i 'name|edition|domain|limit'

# Extract just the license key ID
plesk bin keyinfo -l | grep -i plesk_key_id

# Show the expiration date
plesk bin keyinfo -l | egrep -i 'expir|valid|expire'

# Quick, human-friendly summary (best effort)
(echo -n 'Plesk: '; plesk version | head -n1 | cut -d: -f2-) && \
(echo -n 'License ID: '; plesk bin keyinfo -l | awk -F': ' '/plesk_key_id/{print $2;exit}') && \
(echo -n 'Domain limit: '; plesk bin keyinfo -l | awk -F': ' '/domain.*limit|domains/{print $2;exit}') && \
(echo -n 'Expires: '; plesk bin keyinfo -l | awk -F': ' '/expir/{print $2;exit}')

# Show edition-ish hints (name/edition/domain limit lines)

plesk bin keyinfo -l | egrep -i 'name|edition|domain|limit'

# Extract just the license key ID

plesk bin keyinfo -l | grep -i plesk_key_id

# Show the expiration date

plesk bin keyinfo -l | egrep -i 'expir|valid|expire'

# Quick, human-friendly summary (best effort)

(echo -n 'Plesk: '; plesk version | head -n1 | cut -d: -f2-) && \

(echo -n 'License ID: '; plesk bin keyinfo -l | awk -F': ' '/plesk_key_id/{print $2;exit}') && \

(echo -n 'Domain limit: '; plesk bin keyinfo -l | awk -F': ' '/domain.*limit|domains/{print $2;exit}') && \

(echo -n 'Expires: '; plesk bin keyinfo -l | awk -F': ' '/expir/{print $2;exit}')

Troubleshooting

Command not found: Use the absolute path /usr/sbin/plesk or ensure /usr/sbin is in your PATH.
Insufficient privileges: Run as root or prepend sudo.
License looks outdated/invalid after IP change or upgrade:

# Validate current license (exit 0 = valid) plesk bin license -c # Re-fetch from Plesk’s licensing servers plesk bin license --retrieve

1
2
3
4
5
6

# Validate current license (exit 0 = valid)
plesk bin license -c

# Re-fetch from Plesk’s licensing servers
plesk bin license --retrieve
Plesk services down but you need the key number:

# Fallback: read the key registry directly (Linux) grep "<name>PLSK" /etc/sw/keys/registry.xml

1
2
3

# Fallback: read the key registry directly (Linux)
grep "<name>PLSK" /etc/sw/keys/registry.xml

FAQ

Q: Where is the edition name printed exactly?
A: It’s not always labeled as “Edition.” Many keys show a product name or description and always include limits. The domain limit is the most consistent indicator.

Q: Does the installer version equal the panel version?
A: No. plesk installer --version is for the installer component, useful for debugging but not for the panel’s version string.

Q: Can I script this for inventory?
A: Yes—wrap the one‑liner summary in a loop across hosts and collect outputs to a central log.

Wrap‑Up

To recap:

plesk version tells you exactly which Plesk build you’re on.
plesk bin keyinfo --list reveals the license details.
The domain limit cleanly maps to Web Admin (10), Web Pro (30), or Web Host (Unlimited).
