Self-hosted open-source tools have replaced a bunch of cloud-based platforms for my productivity needs. Take Microsoft 365, for example. I’d rather not spend extra bucks every month just to edit documents when there’s a battalion of tools available in the FOSS ecosystem. Like most tinkerers, I’d initially chosen a local LibreOffice instance as my Microsoft 365 replacement. But as the devices in my tinkering a***nal increased, I switched to a Docker-based LibreOffice Online instance to access my spreadsheets, presentation slides, and text documents.
