Servy includes a command-line interface (CLI) designed for full scripting, automated deployments, and seamless integration into CI/CD pipelines.
The CLI offers a lightweight, script-friendly alternative to the desktop app, focusing on automation and headless use cases while leveraging the same core service management logic as the desktop application.
After installation, the Servy directory is automatically added to the system PATH environment variable. This allows you to run servy-cli.exe directly from any elevated Command Prompt or PowerShell session.
Note
In servy-cli, the equals sign (=) is not supported when using single-character shortcuts (like -c or -p).
To get started, open an elevated Command Prompt or PowerShell window and run:
PS> servy-cli help
Servy.CLI <version>+<commit>
Copyright © 2026 Akram El Assas. All rights reserved.
install Install a new service.
uninstall Uninstall a service.
start Start a Windows service.
stop Stop a Windows service.
status Get the current status of a Windows service. Possible results: Stopped,
StartPending, StopPending, Running, ContinuePending, PausePending, Paused.
restart Restart a Windows service.
export Export a Servy Windows service configuration to a configuration file.
import Import a Windows service configuration into Servy's database.
help Display more information on a specific command.
version Display version information.
For detailed help on any command, append the command name after --help. For example, to get help for the start command:
PS> servy-cli start --help
Servy.CLI <version>+<commit>
Copyright © 2026 Akram El Assas. All rights reserved.
-n, --name Required. Name of the service to start.
-q, --quiet Suppress spinner and run in non-interactive mode.
--help Display this help screen.
--version Display version information.
The main command for installing a Windows service is install.
Quick Example
The following command installs MyApp.exe as a Windows service named MyService:
PS> servy-cli install --name="MyService" --path="C:\path\to\MyApp.exe"
Detailed Usage
Here is its detailed usage:
PS> servy-cli install --help
Servy.CLI <version>+<commit>
Copyright © 2026 Akram El Assas. All rights reserved.
-n, --name Required. Unique service name to install.
--displayName The human-readable name shown in the Windows
Services console (services.msc). If left empty, the
service name will be used instead.
-d, --description Description of the service.
-p, --path Required. Path to the executable process. Supports
environment variable expansion, example:
%JAVA_HOME%\bin\java.exe
--startupDir Startup directory for the process. Supports
environment variable expansion, example:
%PROGRAMDATA%\MyApp
--params Additional parameters for the process. Supports
environment variable expansion, example:
--param="%ProgramData%\MyApp" --param="%MY_VAR%\bin"
--startupType Service startup type. Options: Automatic,
AutomaticDelayedStart, Manual, Disabled.
--priority Process priority level. Options: Idle, BelowNormal,
Normal, AboveNormal, High, RealTime.
--stdout Path to stdout log file.
--stderr Path to stderr log file.
--enableRotation Deprecated. Enable size-based log rotation. This
option is kept only for backward compatibility. Use
--enableSizeRotation instead.
--enableSizeRotation Enable size-based log rotation.
--rotationSize Log rotation size in Megabytes (MB). Must be greater
than or equal to 1 MB.
--enableDateRotation Enable date-based log rotation based on the date
interval specified by --dateRotationType. When both
size-based and date-based rotation are enabled, size
rotation takes precedence.
--dateRotationType Date rotation type. Options: Daily, Weekly, Monthly.
--maxRotations Maximum rotated log files to keep. Set to 0 or leave
empty for unlimited.
--useLocalTimeForRotation Use local server time for log rotation instead of
UTC. Default is false.
--enableHealth Enable health monitoring.
--heartbeatInterval Heartbeat interval in seconds.
--maxFailedChecks Maximum allowed failed health checks.
--recoveryAction Recovery action on failure. Options: None,
RestartService, RestartProcess, RestartComputer.
Restart service and restart computer actions are not
available if the service runs under NT
AUTHORITY\NetworkService, NT AUTHORITY\LocalService,
or a user account without the required privileges.
Only the restart process action will be available
for these accounts.
--maxRestartAttempts Maximum restart attempts on failure. Set to 0 for
unlimited restart attempts.
--failureProgramPath The failure program path. Configure a script or
executable to run when the process fails to start.
If health monitoring is disabled, the program will
run when the process fails to start. If health
monitoring is enabled, the program will only run
after all configured recovery action retries have
failed. Supports environment variable expansion,
example: %JAVA_HOME%\bin\java.exe
--failureProgramStartupDir Specifies the directory in which the failure program
will start. Defaults to the failure program
directory. Supports environment variable expansion,
example: %PROGRAMDATA%\MyApp
--failureProgramParams Additional parameters for the failure program.
--envVars Environment variables for the process. Enter
variables in the format varName=varValue separated
by semicolons (;). Use \= to escape '=', \" to
escape '"', \; to escape ';' and \\ to escape '\'.
Supports environment variable expansion, example:
VAR1=%ProgramData%\MyApp; VAR2=%VAR1%\bin
--deps Specify one or more Windows service names (not
display names) that this service depends on
separated with semicolons (;). Use service key names
without spaces or special characters. Each
dependency service must be installed and running
before this service can start. If a dependency's
start type is Automatic, Windows will try to start
it automatically before this service. If a
dependency fails to start or is disabled, this
service will not start.
--user The service account username (e.g., .\username,
DOMAIN\username, or DOMAIN\gMSA$). If this option is
not set, the service runs under Local System. If the
service runs under an account other than Local
System, you must grant write access to
%ProgramData%\Servy for the account that runs the
service.
--password The service account password. SECURITY WARNING: Use
the SERVY_PASSWORD environment variable instead to
avoid exposing credentials in OS process listings.
--preLaunchPath The pre-launch executable path. Configure an
optional script or executable to run before the main
service starts. This is useful for preparing
configurations, fetching secrets, or other setup
tasks. If the pre-launch script fails, the service
will not start unless you enable
--preLaunchIgnoreFailure. Supports environment
variable expansion, example:
%JAVA_HOME%\bin\java.exe
--preLaunchStartupDir Specifies the directory in which the pre-launch
executable will start. Defaults to the service
working directory. Supports environment variable
expansion, example: %PROGRAMDATA%\MyApp
--preLaunchParams Additional parameters for the pre-launch executable.
--preLaunchEnv Environment variables for the pre-launch executable.
Enter variables in the format varName=varValue
separated by semicolons (;). Use \= to escape '=',
\" to escape '"', \; to escape ';' and \\ to escape
'\'. Supports environment variable expansion,
example: VAR1=%ProgramData%\MyApp; VAR2=%VAR1%\bin
--preLaunchStdout Path to stdout log file of the pre-launch
executable.
--preLaunchStderr Path to stderr log file of the pre-launch
executable.
--preLaunchTimeout Timeout for the pre-launch executable. Set the
timeout to 0 to run the pre-launch hook in
fire-and-forget mode. When set to 0, the hook is
started and the service is launched immediately
without waiting for completion. Use this only for
tasks that do not affect the service's ability to
start or run correctly. Stdout/Stderr redirection
and retries are not available in fire-and-forget
mode.
--preLaunchRetryAttempts Number of retry attempts for the pre-launch
executable if it fails. Must be greater or equal to
0.
--preLaunchIgnoreFailure Ignore failure and start service even if pre-launch
executable fails.
--postLaunchPath The post-launch executable path. Configure an
optional script or executable to run after the
process starts successfully. Supports environment
variable expansion, example:
%JAVA_HOME%\bin\java.exe
--postLaunchStartupDir Specifies the directory in which the post-launch
executable will start. Defaults to the directory of
the post-launch program. Supports environment
variable expansion, example: %PROGRAMDATA%\MyApp
--postLaunchParams Additional parameters for the post-launch
executable.
--debug Whether debug logs are enabled. When enabled,
environment variables and process parameters are
recorded in the Servy.Service.log file. Not
recommended for production environments, as these
logs may contain sensitive information.
--startTimeout Timeout in seconds to wait for the process to start
successfully before considering the startup as
failed. Must be greater than or equal to 1 second.
Defaults to 10 seconds.
--stopTimeout Timeout in seconds to wait for the process to exit.
Must be greater than or equal to 1 second. Defaults
to 5 seconds.
--preStopPath The pre-stop executable path. Configure an optional
script or executable to run before the main service
stops. This can be used for graceful shutdown tasks
such as notifying external systems or draining
resources. The pre-stop process runs synchronously
and extends the service stop timeout while it is
running. Set the timeout to 0 to run the pre-stop
process in fire-and-forget mode. Supports
environment variable expansion, example:
%JAVA_HOME%\bin\java.exe
--preStopStartupDir Specifies the directory in which the pre-stop
executable will start. Defaults to the directory of
the pre-stop program. Supports environment variable
expansion, example: %PROGRAMDATA%\MyApp
--preStopParams Additional parameters for the pre-stop executable.
--preStopTimeout Timeout for the pre-stop executable. Set the timeout
to 0 to run the pre-stop process in fire-and-forget
mode.
--preStopLogAsError Log pre-stop failure as error.
--postStopPath The post-stop executable path. Configure an optional
script or executable to run after the wrapped
process and all of its child processes have exited.
The post-stop process is started in fire-and-forget
mode and does not block service shutdown. Supports
environment variable expansion, example:
%JAVA_HOME%\bin\java.exe
--postStopStartupDir Specifies the directory in which the post-stop
executable will start. Defaults to the directory of
the post-stop program. Supports environment variable
expansion, example: %PROGRAMDATA%\MyApp
--postStopParams Additional parameters for the post-stop executable.
-q, --quiet Suppress spinner and run in non-interactive mode.
--help Display this help screen.
--version Display version information.
Note
If the value of --params in install command includes arguments that start with --, use an equals sign (=) to prevent parsing issues. Example: --params="--mode=production --port=7008" Without the equals sign, the CLI might interpret --mode or --port as its own options instead of part of the service parameters.
Important
Security Best Practice: Avoid using the --password flag in production or scripts. Passing passwords as CLI arguments makes them visible in the Windows Process List and shell history. Instead, set the SERVY_PASSWORD environment variable before running the install command.
Below is the recommended way to install a service with credentials:
# 1. Set the password in the current process environment
$env:SERVY_PASSWORD = "your_secret_password"
# 2. Run the install command without the --password flag
servy-cli install `
