COS Dev Center

COS Dev Center opens by itself at first boot and asks what you need. Instead of hunting for a tutorial to install local AI, Node.js or Docker, you pick from a list and it does the work — asking for the administrator password only when it genuinely has to.

It is exclusive to CapivaraOS and ships on all three desktop editions. To open it later, look for COS Dev Center in the application menu.

Install to disk before using it

Several items download multiple gigabytes. In a live session (running from the USB stick) space is limited and everything is lost at shutdown. Install the system first.

What it offers

Local AI

Installs the stack to run AI models on your own machine, with no cloud and no account:

  • Ollama — the engine that runs the models
  • Alpaca — a graphical interface to talk to them
  • Continue — the extension that brings AI into the editor

This downloads several gigabytes

On Fedora 45 the ollama package depends on ollama-rocm, the AMD GPU support. It gets installed even on machines with no AMD card, and it alone is a few gigabytes. This is not our choice: it is how the package is built in Fedora. Make room and give it a decent connection.

Without a dedicated GPU the models run on the CPU. That works, but it is slower — prefer smaller models.

Language tracks

Installs languages in your user account, through mise, without touching the system:

Web/JavaScript (Node.js) · Python · Go · Rust · Java

Because nothing goes into the system, you can keep different versions per project and remove everything without a trace. Open a new terminal after installing, or your PATH is still the old one.

Enable GPU (NVIDIA)

Installs the proprietary NVIDIA driver and CUDA from RPM Fusion, to accelerate local AI.

It is NVIDIA only. On AMD cards the acceleration already comes with local AI, through ROCm. With no dedicated GPU there is nothing to enable — AI runs on the CPU.

Dev tools

You choose which ones to install:

  • VS Code — Microsoft's editor (system-wide, asks for the password)
  • Cline — an AI agent inside the editor
  • Open WebUI — a web chat interface for Ollama, in a podman container
  • Docker CE — containers (system-wide, asks for the password)

GitHub CLI + pre-commit

Sets up gh, for using GitHub from the terminal, and installs a pre-commit template with security checks that run before every commit: gitleaks (looks for leaking secrets), key detection and ShellCheck on scripts.

How it behaves

One task at a time. While an installation runs, the others are blocked — this keeps two package transactions from fighting over the system.

The "Installed" section shows what you already installed through it, so you do not repeat yourself.

The password is asked only when needed. Language tracks and Open WebUI live in your user account and ask for nothing. VS Code, Docker and the NVIDIA driver touch the system and do ask.

There is also COS Config Center

The Dev Center takes care of the development environment. For system settings — codecs, keyboard, language, firewall, disks, network — the application is COS Config Center.
