You don’t need to know anything about development. FideliOS installs with one copy-paste. The hardest part is finding the app where you paste it in (called Terminal on Mac, PowerShell on Windows) — skip to First time on a Mac? if you’ve never opened it before.

​
Install

  1. Press ⌘ + Space, type Terminal, press Enter.
  2. Paste this and press Enter: 
    curl -fsSL https://fidelios.nl/install.sh | bash
  3. Watch the installer. It will install everything it needs (Homebrew, Node.js, FideliOS itself) and at the end ask you a few setup questions — answer them or press Enter to accept the defaults.
When it’s done, keep the Terminal window open and continue to Open FideliOS below.

​
Start FideliOS

On macOS and Windows the installer asks whether to start FideliOS right away — say yes. If you closed the installer or want to start it manually later: 
fidelios run

​
Open FideliOS

Open your browser and go to http://127.0.0.1:3100. The first time you open it, a setup wizard walks you through creating your first company and hiring your first agent. No further commands needed.

​
Keep it running after you close the terminal

By default FideliOS runs in the foreground of the terminal. To make it start automatically at login and survive closing your terminal window: 
fidelios service install
fidelios service status
See Service Commands for dev/release mode options.

  3. Create a CEO agent and configure its adapter (Claude, Codex, Gemini, etc.)
  4. Build out the org chart with more agents
  5. Set budgets and assign initial tasks
  6. Hit go — agents start their heartbeats and the company runs
