← Documents and knowledge
Collabora Online: browser office. Edit documents online on your own server.

In simple English

This is an online office suite that runs inside a web browser. Multiple people can edit the same document at the same time. You can host it on your own server to keep your files private. The software is free to use. Setting it up takes technical skill and server upkeep.

What it is

Collabora Online is a web-based office suite built on LibreOffice technology. This GitHub repository acts as an issue tracker and a place to find container images, while the actual code lives on a separate development server.

What it is good for

Solo builders who want a private, self-hosted alternative to cloud document editors will find this useful. It removes reliance on big tech companies for everyday word processing and spreadsheet work.

Good
  • Edits text documents, spreadsheets and presentations directly in a web browser.
  • Allows multiple users to work on the same file simultaneously.
  • Runs on private infrastructure to keep sensitive data under your control.
Watch for
  • Requires Docker (a way to run a program inside its own sealed box, so it cannot break anything else on your server) or Kubernetes for installation.
  • Needs at least 2 GB of memory to run smoothly, so check your server has room.
  • Development happens on an external code review server rather than GitHub.
