Get FideliOS running on Windows with a single command.

​
Prerequisites

  • Windows 10 or 11 (64-bit)
  • PowerShell 5.1 or later (built-in on Windows 10+)
No other software required. The installer handles everything.

​
Install

Open PowerShell (search the Start menu for “PowerShell”) and run: 
iwr -useb https://fidelios.nl/install.ps1 | iex
The script:
  1. Checks for Node.js and installs it if missing
  2. Installs the fidelios CLI
  3. Runs a quick health check
If you see a security warning about running scripts, open PowerShell as Administrator and run: Set-ExecutionPolicy RemoteSigned -Scope CurrentUser Then retry the install command.

​
Start FideliOS

fidelios run
Then open http://127.0.0.1:3100 in your browser. The first time you open it, a setup wizard walks you through creating your first company and hiring your first agent.

​
Stop and Restart

Press Ctrl+C in the PowerShell window to stop FideliOS. To start it again: 
fidelios run
Your data is preserved between restarts.

​
Using WSL (Optional)

If you already use Windows Subsystem for Linux (WSL), you can run the Linux installer inside your WSL terminal instead: 
curl -fsSL https://fidelios.nl/install-linux.sh | bash
Then follow the Linux install guide. The FideliOS UI is still accessible from your Windows browser at http://127.0.0.1:3100.
