Introduction

Servy can turn any app into a native Windows service. On this page you'll find examples for the most popular languages and frameworks, ready to run as background services.

Services can be installed and configured easily through the Servy Desktop App or the PowerShell module, but this page focuses on real-world examples using the Servy CLI for automation, scripting, and CI/CD scenarios.

Once installed, the CLI executable is available at:

C:\Program Files\Servy\servy-cli.exe

Note on --params Usage

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.

Run a Node.js / Express App as a Service

servy-cli install `
  --name="MyNodeApp" `
  --description="Node.js Express API" `
  --path="C:\Program Files\nodejs\node.exe" `
  --params="C:\apps\myapp\server.js" `
  --startupDir="C:\apps\myapp" `
  --startupType="Automatic"

Run a Deno App as a Service

servy-cli install `
  --name="MyDenoService" `
  --description="Deno background script" `
  --path="C:\tools\deno\deno.exe" `
  --params="run --allow-net C:\apps\deno\worker.ts" `
  --startupDir="C:\apps\deno" `
  --startupType="Automatic"

Notes:

• The --allow-net flag is just an example; add other permissions (--allow-read, --allow-write, etc.) as needed.
• Works for both scripts and Deno HTTP servers.

Run a Bun App as a Service

servy-cli install `
  --name="MyBunService" `
  --description="Bun backend service" `
  --path="C:\tools\bun\bun.exe" `
  --params="C:\apps\bun\server.ts" `
  --startupDir="C:\apps\bun" `
  --startupType="Automatic"

Notes:

• Bun automatically detects whether the file is a script or server.
• You can pass arguments like --port 3000 in --params if needed.

Run a Python Script as a Service

servy-cli install `
  --name="MyPythonJob" `
  --description="Python background job" `

  --startupDir="C:\apps\scripts" `
  --startupType="Automatic"

Run a Go App as a Service

servy-cli install `
  --name="MyGoService" `
  --description="Go background service" `
  --path="C:\apps\my-go-app\my-go-app.exe" `

  --name="MyCppService" `
  --description="C++ Application" `
  --path="C:\apps\cpp-service\service.exe" `
  --startupDir="C:\apps\cpp-service" `
  --startupType="Automatic"

Run a PHP App as a Service

servy-cli install `
  --name="MyPHPWorker" `
  --description="PHP queue worker" `

  --startupType="Automatic"

Run a .NET App as a Service

servy-cli install `
  --name="MyDotNetApp" `
  --description=".NET Worker Service" `
  --path="C:\apps\dotnetapp\MyApp.exe" `
  --startupDir="C:\apps\dotnetapp" `
  --startupType="Automatic"

Or, if using dotnet runtime with a DLL:

  --name="MyDotNetApp" `
  --description=".NET Worker Service" `
  --path="C:\Program Files\dotnet\dotnet.exe" `
  --params="C:\apps\dotnetapp\app.dll" `
  --startupDir="C:\apps\dotnetapp" `
  --startupType="Automatic"

Run a PowerShell script as a Service

servy-cli install `
  --name="MyPowerShellScript" `
  --description="Batch automation job" `
  --path="C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" `
  --params='-File \"C:\scripts\script\my script.ps1\"' `
  --startupDir="C:\scripts\script" `
  --startupType="Automatic" 

Run a Batch File as a Service

servy-cli install `
  --name="MyBatchScript" `
  --description="Batch automation job" `
  --path="C:\Windows\System32\cmd.exe" `
  --params="/c C:\scripts\backup-job.bat" `
  --startupDir="C:\scripts" `
  --startupType="Automatic"

Run an AutoHotkey script as a Service

servy-cli install `
  --name="MyAutoHotkeyService" `
  --description="Batch automation job" `
  --path="C:\Program Files\AutoHotkey\v2\AutoHotkey.exe" `
  --params="C:\scripts\service.ahk" `
  --startupDir="C:\scripts" `
  --startupType="Automatic"

You can find a sample AutoHotkey script here.

Running an AutoHotkey script as a service gives you clear advantages, but also some limits, and it really depends on what your script does.

When a script runs as a service, it can start immediately when Windows starts. It does not have to wait for a user to log in, so it is great for scripts that should always be running in the background, even on a machine that stays logged out most of the time. This is helpful for automation tasks that do not depend on the desktop, such as file monitoring, network checks, background cleanup or anything that works quietly without talking to the user.

The main limitation is that Windows services cannot normally interact with the desktop. This means hotkeys, mouse actions, sending keystrokes and interacting with windows on the screen will not work when the script runs as a service. These kinds of features require a user session, so they only work if the script runs after login, for example through the Startup folder or the Task Scheduler with "run at logon".

A service is useful when you want something to run early and silently with no user involved. But if your AutoHotkey script needs to press keys, respond to hotkeys, show windows or control applications on the screen, then running it as a service will not work well. In that case, starting it after login is the right option.

Run a VBScript as a Service

servy-cli install `
  --name="MyVBScript" `
  --description="VBScript automation job" `
  --path="C:\Windows\System32\cscript.exe" `
  --params="C:\scripts\tasks\job.vbs" `
  --startupDir="C:\scripts\tasks" `
  --startupType="Automatic"

If you prefer wscript.exe (windowed, but still works as a service):

servy-cli install `
  --name="MyVBScript" `
  --description="VBScript automation job" `
  --path="C:\Windows\System32\wscript.exe" `
  --params="C:\scripts\tasks\job.vbs" `
  --startupDir="C:\scripts\tasks" `
  --startupType="Automatic"

Run a WSL Bash Script as a Service

servy-cli install `
  --name="MyWSLScript" `
  --description="WSL Bash script service" `
  --path="C:\Windows\System32\wsl.exe" `
  --params="bash /home/user/scripts/run.sh" `
  --startupDir="C:\Windows\System32" `
  --startupType="Automatic"

If you need a specific distribution:

servy-cli install `
  --name="MyUbuntuWSLService" `
  --description="WSL Ubuntu service job" `
  --path="C:\Windows\System32\wsl.exe" `
  --params="-d Ubuntu bash /home/user/app/start.sh" `
  --startupDir="C:\Windows\System32" `
  --startupType="Automatic"

Run a Julia Script as a Service

(Used for ML jobs, analytics, long-running computation workers)

servy-cli install `
  --name="MyJuliaService" `
  --description="Julia analytics worker" `
  --path="C:\Julia-1.10\bin\julia.exe" `
  --params="C:\apps\julia\worker.jl" `
  --startupDir="C:\apps\julia" `
  --startupType="Automatic"

Run a Dart Server or Script as a Service

(Shelf web services, background workers, API servers, etc.)

servy-cli install `
  --name="MyDartService" `
  --description="Dart backend service" `
  --path="C:\tools\dart-sdk\bin\dart.exe" `
  --params="C:\apps\dart\server.dart" `
  --startupDir="C:\apps\dart" `
  --startupType="Automatic"

Run an R Script as a Service

servy-cli install `
  --name="MyRService" `
  --description="R background job" `
  --path="C:\Program Files\R\R-4.4.1\bin\Rscript.exe" `
  --params="C:\apps\r\job.R" `
  --startupDir="C:\apps\r" `
  --startupType="Automatic"

Run a Lua Script as a Service

servy-cli install `
  --name="MyLuaService" `
  --description="Lua automation script" `
  --path="C:\Lua\5.4\lua.exe" `
  --params="C:\apps\lua\script.lua" `
  --startupDir="C:\apps\lua" `
  --startupType="Automatic"

Run a Perl Script as a Service

servy-cli install `
  --name="MyPerlService" `
  --description="Perl Script" `
  --path="C:\Perl64\bin\perl.exe" `
  --params="C:\apps\perl-task\task.pl" `
  --startupDir="C:\apps\perl-task" `
  --startupType="Automatic"

Run an OCaml Script or App as a Service

servy-cli install `
  --name="MyOCamlService" `
  --description="OCaml background worker" `
  --path="C:\OCaml\bin\ocaml.exe" `
  --params="C:\apps\ocaml\worker.ml" `
  --startupDir="C:\apps\ocaml" `
  --startupType="Automatic"

If you compiled your OCaml code to a native executable (e.g., worker.exe), you can skip ocaml.exe and set --path directly to the executable:

servy-cli install `
  --name="MyOCamlService" `
  --description="OCaml compiled worker" `
  --path="C:\apps\ocaml\worker.exe" `
  --startupDir="C:\apps\ocaml" `
  --startupType="Automatic"

This way, you can run either scripts or compiled OCaml apps as Windows services using Servy.

Run a Zig App as a Service

servy-cli install `
  --name="MyZigService" `
  --description="Zig background worker" `
  --path="C:\apps\zig\myapp.exe" `
  --startupDir="C:\apps\zig" `
  --startupType="Automatic"

Run a Pascal/Delphi App as a Service

servy-cli install `
  --name="MyPascalService" `
  --description="Delphi background app" `
  --path="C:\apps\pascal\worker.exe" `
  --startupDir="C:\apps\pascal" `
  --startupType="Automatic"

Run a Fortran App as a Service

servy-cli install `
  --name="MyFortranService" `
  --description="Fortran computational service" `
  --path="C:\apps\fortran\worker.exe" `
  --startupDir="C:\apps\fortran" `
  --startupType="Automatic"

Run an Elixir Script as a Service

servy-cli install `
  --name="MyElixirService" `
  --description="Elixir background worker" `
  --path="C:\Program Files\Elixir\bin\elixir.bat" `
  --params="C:\apps\elixir\worker.exs" `
  --startupDir="C:\apps\elixir" `
  --startupType="Automatic"

For Elixir, you can point --params to any .exs script or mix task.

Run an Erlang Script as a Service

servy-cli install `
  --name="MyErlangService" `
  --description="Erlang background worker" `
  --path="C:\Program Files\erl-25.3\bin\erl.exe" `
  --params="-noshell -s my_app start -s init stop" `
  --startupDir="C:\apps\erlang" `
  --startupType="Automatic"

For Erlang, the -s parameters start the desired module and function. Adjust according to your OTP app.

Tips & Notes

Tip: You can view and manage all installed services visually using Servy Manager, or automate deployments via Servy CLI.
