Why Developers Choose AlwaysUp

Run Your Code as a Windows Service

AlwaysUp provides a reliable, time-tested way to turn your app into a service — fast. Programmers use AlwaysUp to:

• Run Python, Node.js, .NET, Java, or batch scripts in the background
• Automatically restart long-running scripts if they crash or hang
• Start background processes at boot, even with no user logged in
• Deploy custom tools and microservices reliably in production

Works with Your Tech Stack

AlwaysUp supports any executable or command-line tool that runs under Windows, including:

• Batch files: startserver.bat (see our guide)
• Python: python your_script.py (see our guide)
• Node.js: node app.js (see our guide)
• Java: java -jar YourApplication.jar (see our guide)
• .NET Core: dotnet MyApp.dll
• Your own custom EXEs: C:\apps\yourapp.exe -c C:\config.xml

Monitor & Recover Automatically

Once deployed, AlwaysUp watches your application for crashes, hangs, or unexpected exits. You can also:

• Set up auto-restart rules with delays and retries
• Receive email alerts if your application stops for any reason
• Log output (stdout/stderr) and crash messages to a file to aid debugging
• Extend monitoring with your own, custom failure detection, to let AlwaysUp know when your application is in trouble and needs to be restarted
