Nearly every media application, from VLC to YouTube's pipeline, stands on its shoulders.
• fish shellsystemActiveGPL-2.0-only2026-07-05fish-shell contributors — The "friendly interactive shell": autosuggestions, syntax highlighting and sane completions that work out of the box, with no configuration required. Recently rewritten from C++ to Rust entirely in the open.
• FlatpaksystemActiveLGPL-2.1-or-later2026-07-05Flatpak community — Distribution-independent application packaging and sandboxing for the Linux desktop: one build runs everywhere, with portals mediating access to user data. Together with Flathub it gave the free desktop a common software channel.
• FreeCADgraphicsActiveLGPL-2.1-or-later2026-07-05FreeCAD community — Parametric 3D CAD modeller for real engineering: mechanical design, architecture, finite-element analysis and CNC, with a full Python API. Version 1.0 in 2024 marked two decades of building a free alternative to locked-in CAD ecosystems.
• GIMPgraphicsActiveGPL-3.0-or-later2026-07-02GIMP Development Team / GNOME Project — The GNU Image Manipulation Program — a free raster graphics editor for photo retouching, image composition and digital painting, scriptable in Script-Fu and Python. Its development in the mid-1990s gave birth to the GTK toolkit, the foundation on which the entire GNOME desktop was later built.
• GitdevelopmentActiveGPL-2.0-only2026-07-02Linus Torvalds, Junio C Hamano & contributors — Distributed version control system written by Linus Torvalds in 2005 for Linux kernel development after the BitKeeper licence dispute. Its content-addressed model made every clone a full backup of a project's history — a preservation property that reshaped how software is kept and shared.
• GNOME Web (Epiphany)browsersActiveGPL-3.0-or-later2026-07-05GNOME Project — GNOME Web, the desktop's native browser built on WebKitGTK — a deliberately simple, distraction-free window onto the web that keeps a second independent engine alive on Linux.
• GNU Compiler CollectiondevelopmentActiveGPL-3.0-or-later2026-07-05GNU Project — The GNU Compiler Collection, the free compiler Richard Stallman began in 1987 that made the rest of free software possible — for decades the compiler that built the world's operating systems, and still the reference for C and C++ on free platforms.
• GNU EmacsdevelopmentActiveGPL-3.0-or-later2026-07-02Free Software Foundation — The extensible, self-documenting text editor, in continuous development since 1976 and one of the founding programs of the GNU project and the free software movement itself. Its Emacs Lisp core lets it become anything — mail reader, organiser, IDE — which is why it has outlived generations of editors.
• GNU TeXmacsofficeActiveGPL-3.0-or-later2026-07-05GNU Project / TeXmacs contributors — Scientific editing platform producing publication-quality documents with live mathematics, interfaces to computer algebra systems and structured editing — inspired by TeX and Emacs but sharing code with neither.
• GnuCashofficeActiveGPL-2.0-or-later2026-07-05GnuCash community — Double-entry accounting software for personal and small-business finance — accounts, invoices, reports and bank imports, maintained continuously since 1997. Financial records are exactly the kind of data that must outlive any vendor.
• GnuPGsecurityActiveGPL-3.0-or-later2026-07-05GNU Project / g10 Code — The GNU Privacy Guard, the free implementation of the OpenPGP standard that encrypts and signs email, files and, crucially, the software packages of nearly every Linux distribution. Werner Koch has maintained this foundation of digital trust since 1997.
• GodevelopmentActiveBSD-3-Clause2026-07-02Google & Go community — Statically typed compiled language from Google (2009) designed for simplicity, fast builds and effortless concurrency. It became the language of cloud infrastructure — Docker, Kubernetes and much of the container ecosystem are written in it.
• Godot EnginedevelopmentActiveMIT2026-07-05Godot community — Feature-complete 2D and 3D game engine with its own scripting language, visual editor and one-click export to every platform, under the permissive MIT licence. After commercial engines burned developer trust in 2023, it became the community's engine of choice.

For twenty years the tool reached for when disks must be reorganised without losing data.
• HandBrakemultimediaActiveGPL-2.0-only2026-07-02HandBrake Team — Open source video transcoder that converts nearly any video into modern, widely supported formats, with batteries-included presets for every device. For two decades it has been the standard tool for ripping and re-encoding personal media collections.
• Home AssistantsystemActiveApache-2.02026-07-02Open Home Foundation — Open source home automation hub that puts local control and privacy first, integrating thousands of devices without any cloud dependency. Under the Open Home Foundation it is one of the most active open source projects in the world.
• HugointernetActiveApache-2.02026-07-05Hugo Authors — Static site generator written in Go and famous for its build speed — thousands of pages rendered in seconds from Markdown. Sites built with it are plain files, trivially mirrored and effectively immortal.
• InkscapegraphicsActiveGPL-3.0-or-later2026-07-02Inkscape Project / Software Freedom Conservancy — Professional vector graphics editor built around the open SVG standard, used for illustration, logo design, technical drawing and print preparation. Forked from Sodipodi in 2003, it proved that a community project can carry a full professional design tool.
• IPFS KubointernetActiveApache-2.02026-07-05IPFS / Protocol Labs community — The reference implementation of IPFS, the content-addressed peer-to-peer file system where data is found by what it is, not where it sits. Content addressing is a foundational technique for censorship-resistant preservation.
