Linux, macOS or a server — Docker

There's no installer for Linux or macOS. With Docker installed, the app starts with these commands:

Linux / macOS 
# get the code and the config
$ git clone https://github.com/braindeadpt/OficinaOS.git
$ cd OficinaOS && cp .env.example .env

# start with docker (seed only the first time)
$ docker compose up -d
$ docker compose exec app bun run db:seed

# then open in the browser
http://localhost:4000

Edit .env before starting (initial admin password and APP_URL). Details in the installation guide.

No admin rights?

The portable version runs from a folder (even a USB stick), without installing anything.

Download the portable version (.zip)

After downloading

  1. Open OficinaOS-Setup.exe

    It's in your Downloads folder. Double-click it.

  2. If Windows says «Windows protected your PC»

    Click «More info» and then «Run anyway». The warning shows because the installer isn't digitally signed yet, so Windows doesn't recognise it. It's not a virus: all the code is on GitHub and you can verify the file with the SHA-256.

    Recreation of the Microsoft Defender SmartScreen warning in two steps: first «More info», then «Run anyway».

  3. Accept the administrator prompt

    Only once, to install the service, the firewall rule and the backup task. Everything else is automatic.

  4. Sign in to the app

    At the end your browser opens http://localhost:4000. First sign-in: user admin, password braindead — the app makes you change both. On other devices on the network: http://oficinaos.local:4000.
