Yes, you can absolutely install it yourself. Because Euro-Office is fully open source (licensed under the AGPLv3), you don’t need to buy a platform like Canvos to use it.

Like ONLYOFFICE, Euro-Office is split into two parts:

1. The Document Server: The heavy-lifting engine (handles the rendering, text parsing, and calculations).
2. The Connector: A lightweight plugin for your frontend platform (like Nextcloud, XWiki, or OpenProject) that embeds the editors via an iframe.

Setting it up requires a self-hosted environment. The Docker method is the easiest way to get it running, though native packages for Ubuntu/Debian (.deb) and Fedora (.rpm) are also available.

Step 1: Spin up the Euro-Office Document Server (via Docker)

The document server requires a decent amount of horsepower—the creators recommend a bare minimum of 4 GB RAM (8 GB is better) and 10 GB of disk space.

Run the following command to start the container. Make sure to generate a strong, random JSON Web Token (JWT) secret to secure communication between your frontend and the document server:

docker run -i -t -d -p 8080:80 --restart always \
  -e JWT_ENABLED="true" \
  -e JWT_SECRET="your_very_long_random_secret_here" \
  -e JWT_HEADER="Authorization" \
  eurooffice/documentserver:latest

Pro Tip: In production, you shouldn’t expose port 8080 directly to the web. Instead, point a domain name (like office.yourdomain.com) to your server and set up a reverse proxy (like Nginx, Caddy, or Traefik) to handle HTTPS/SSL. The editor must run over HTTPS if your cloud platform uses HTTPS.

Step 2: Connect it to Nextcloud

Euro-Office features first-class, built-in integration with Nextcloud (version 33 or newer).

1. Install the Connector: Log into your Nextcloud instance as an admin, head to Apps $\rightarrow$ Office & Text, look for Euro-Office integration, and click Download and enable.
2. Configure the Settings: Navigate to Settings $\rightarrow$ Administration $\rightarrow$ Euro-Office.
3. Link the Servers:

• In the Document Server URL field, enter the address of your newly installed server (e.g., [https://office.yourdomain.com](https://office.yourdomain.com)).
• In the Secret Key field, paste the exact JWT_SECRET string you used when launching the Docker container.

4. Save: Click save, and Nextcloud will test the link. Once it turns green, clicking any .docx, .xlsx, or .pptx file in your cloud will automatically launch the Euro-Office editor.

If you prefer to avoid manually dealing with Docker and web servers, the official Nextcloud All-in-One (AIO) installer lets you seamlessly check a box to deploy Euro-Office alongside your cloud environment automatically.
