Radicale is a tiny open-source CalDAV and CardDAV server: a single Python process serving your calendars and contacts to all your devices from your own machine or server. No interface, no company, no data leaving your control. Setup is command-line territory, and every device needs manual configuration. The purist’s choice, and famously light on resources.
Tuta’s calendar comes encrypted the same way as its mail: appointment titles, locations and details are unreadable to the server, and the free tier includes it. German jurisdiction, open-source apps, no ads anywhere. Sharing calendars with outside users is limited by the encryption model, and it works best inside the Tuta ecosystem. The most private […]
OpenShot aims at first-time editors: a simple track layout, drag-and-drop everything, titles and animations included, across all desktop systems. Open source and approachable. Stability on long projects has been its historical weak point, and it lacks the depth the other two editors offer. The gentlest entry into video editing without an account anywhere.
Kdenlive is a full professional-grade video editor from the KDE community: multi-track timelines, proxy editing for weak machines, effects and titles, and no watermark, subscription or telemetry anywhere. It has matured into a genuine Premiere alternative. Rendering speed depends on your hardware, and complex projects demand a learning session. For free software editing, this is […]
Shotcut is an open-source editor with a wide format support thanks to FFmpeg, dockable panels you can arrange to taste, and 4K editing on modest hardware. Windows, macOS and Linux builds from one project. The interface takes an afternoon to feel natural, and some advanced effects are rudimentary. A dependable workhorse without strings.
Vikunja is open-source task management you can host yourself or use hosted: lists, kanban boards, Gantt charts, labels and team sharing, with apps and CalDAV support. Your tasks, your server, your rules. Self-hosting is the intended path, so there is a small maintenance footprint, and the hosted option exists if you would rather not. To-do […]
CryptPad: Collaborating on documents with encryption built into the service.
ONLYOFFICE offers the closest-to-Microsoft formatting among open-source suites, with online collaboration you can self-host in your own Nextcloud or on your own server. Desktop and mobile apps are free as well. The full-featured server edition sits behind commercial licensing tiers, and the document editor is heavier than LibreOffice on old machines. Compatibility first, ideology second.
LibreOffice: Working on office documents with a desktop suite.
Joplin is open-source note taking with end-to-end encrypted sync to storage you control: Nextcloud, WebDAV, or the cloud of your choice. Markdown-based, with web clipper, notebook organization and apps on every platform. The interface is utilitarian and sync setup takes ten minutes of your attention. In exchange, your notes outlive any company.
