The cBioPortal for Cancer Genomics is a resource designed to provide broad community access to cancer genomic data. It provides a unique user-friendly and "biology-centric computational user interface", with the goal of making genomic data more easily accessible to translational scientists, biologists, and clinicians. The interface was explicitly built and continues to evolve with careful usability studies involving multiple biological and clinical users, and an active and engaged user base.

The Cuneiform Digital Library Initiative (CDLI) is a global collaboration of Assyriologists, museum curators, and historians working together to make the world’s earliest written records accessible online. CDLI focuses on cuneiform inscriptions dating back to the very beginning of writing around 3350 BC. Today, more than 500,000 such artifacts are held in museums and private collections worldwide, and CDLI has already digitally catalogued over 350,000 of them, helping researchers and the public explore humanity’s oldest written heritage.

FFmpeg is the leading multimedia framework, able to decode, encode, transcode, mux, demux, stream, filter and play pretty much anything that humans and machines have created. It supports the most obscure ancient formats up to the cutting edge. No matter if they were designed by some standards committee, the community or a corporation. It is also highly portable: FFmpeg compiles, runs, and passes our testing infrastructure FATE across Linux, Mac OS X, Microsoft.
The Global Alliance for Genomics and Health (GA4GH) was formed to help accelerate the potential of genomic medicine to advance human health. It brings together over 400 leading genome institutes and centers with IT industry leaders to create global standards and tools for the secure, privacy respecting and interoperable sharing of Genomic data.
GNU is an operating system consisting entirely of free software, meaning it respects users’ freedom. The GNU operating system consists of GNU packages, which are programs released by the GNU Project, as well as free software released by third parties. The development of GNU made it possible to use a computer without relying on software that restricts or undermines user freedom. The GNU Project is the collective organization of maintainers and developers, webmasters, translators, and other contributors who develop and maintain more than 400 programs that together form the GNU operating system.
GNU Radio is a free & open-source software development toolkit that provides signal processing blocks to implement software radios. It can be used with readily-available low-cost external RF hardware to create software-defined radios, or without hardware in a simulation-like environment. It is widely used in research, industry, academia, government, and hobbyist environments to support both wireless communications research and real-world radio systems.
Graphite is an in-development raster and vector graphics editing suite that's free and open source. It is powered by a node graph compositing engine that fuses layers with nodes, bringing a generative, procedural approach to the workflows of artists, designers, and animators ranging from students and hobbyists to creative professionals and studios.
JabRef is one of the most widely used citation and reference management tools. It helps students and researchers to stay on top of their literature by assisting at every step of a research project: collecting and organizing literature sources, discovering the latest research, citing references in LaTeX and other text editors, and sharing interesting papers with collaborators.
Jitsi is a set of Open Source projects which empower users to deploy secure, scalable and easy to use video conferencing platforms with state-of-the-art video quality and features.
Kiwix provides copies of websites that can be browsed offline. We run scrapers that will crawl a given website and compress it into a single .zim archive (based on the openZIM format). <br/><br/>
KolibriOS is a tiny open-source graphical operating system for x86 (and compatible) architecture computers, developed and maintained by the KolibriOS Project Team. It contains a monolithic kernel that runs in 32-bit protected mode and supports full preemptive multitasking.
Kornia AI is a non-profit organization advancing Spatial Artificial Intelligence through open collaboration. Founded in 2018 and registered as a non-profit in 2023, Kornia AI is supported by a global contributor community. The organization began with Kornia, a widely adopted Python library for Differentiable Computer Vision (>2M downloads/month, 400+ Google Scholar citations).
In recent years, the core maintainers have shifted focus to kornia-rs, a native Rust stack for high‑performance 3D computer vision and spatial AI. Our direction emphasizes robotics and edge deployment: safe, memory‑efficient, low‑latency pipelines that run on constrained devices (e.g., embedded/Jetson‑class hardware). kornia-rs is gaining traction in the open-source community and is used by leading companies such as Farm-ng, Rerun.io, and Copper Robotics, who have featured the project on their platforms.
LibreHealth is the foundation of a worldwide ecosystem of open source Health IT innovation and is a place where people can come together to build tools that enhance the quality of healthcare around the world.
LibreOffice is a modern Free & Open Source Office suite, one of the largest open source projects, and used by millions of users worldwide. LibreOffice is compatible with many file formats like Microsoft® Word, Excel, PowerPoint and Publisher. At its heart though, LibreOffice is built around an open standard, the OpenDocument Format, as its native file format.
LibreOffice is developed by users who, just like you, believe in the principles of Free Software and in sharing their work with the world in non-restrictive ways. The development of LibreOffice is supported by The Document Foundation which provides the infrastructure for the project.
We believe that users should have the freedom to run, copy, distribute, study, change and improve the software that we distribute. While we do offer no-cost downloads of the LibreOffice suite of programs, Free Software is first and foremost a matter of liberty, not price. We campaign for these freedoms because we believe that everyone deserves them.
Though the members of our community hail from many different backgrounds, we all value personal choice and transparency, which translates practically into wider compatibility, more utility, and no end-user lock-in to a single product. We believe that Free Software can provide better-quality, higher-reliability, increased-security, and greater-flexibility than proprietary alternatives. LibreOffice is a large project (approx. 6MLOC), which makes it interestingly complex, but at the same time, provides a place for all sorts of contribution & skills.
The community behind LibreOffice is the heart of the project, without which we would not have the resources to continue developing our software. The passion and drive that every individual brings to the community results in collaborative development that often exceeds our own expectations. With tons of different roles in the project, we invite everyone to join us in our work and help us to make LibreOffice known, prosper, and accessible to all.
The Metasploit Framework is both a penetration testing system and a development platform for creating security tools and exploits. The framework is used by network security professionals to perform penetration tests, system administrators to verify patch installations, product vendors to perform regression testing, and security researchers world-wide. The framework is written in the Ruby programming language and includes components written in C, many flavors of Assembly, Python, Powershell, PHP, and other languages.
