AboutCode.org is a community of open source developers who are trying to make open source easier to use by providing open source tools to discover, identify and track open source components (aka. Software Composition Analysis – SCA). This includes tools, data and standards for code origin, FOSS licenses and security vulnerabilities.
We are dedicated to provide the most effective fuzzing frameworks. Our work includes AFL++, the most effective and flexible fuzzer, and libafl, a library to build your own fuzzer with the most modern techniques and technologies.

Boa is an open-source, embeddable JavaScript engine written in Rust. The project aims to provide a correct, safe, and performant implementation of the ECMAScript specification, with a strong focus on long-term maintainability and developer ergonomics.
CCExtractor Development is the creator of the de-facto captions extraction tool - CCExtractor. It is the one tool that is free, portable, open source and community managed that can take a recording from a TV show and generate an external subtitle file for it.
Cloud Native Computing Foundation (CNCF) serves as the vendor-neutral home for many of the fastest-growing open source projects, including Kubernetes, Prometheus, and Envoy.
The Debian Project is an association of Free Software developers who volunteer their time and effort in order to produce and maintain a completely free operating system Debian. Since its launch, the Debian project has grown to comprise more than 1,000 members with official developer status, alongside many more volunteers and contributors. Today, Debian encompasses over 50,000 packages of free, open source applications and documentation.
DORA (Dataflow-Oriented Robotic Architecture) is middleware designed to streamline and simplify the creation of AI-based robotic applications. It offers low latency, composable, and distributed dataflow capabilities. Applications are modeled as directed graphs, also referred to as pipelines.
Free and open wireless networks
EMBL-EBI is a global centre for biological data, developing and maintaining open data resources and open-source software that support life science research worldwide. Our services are used daily by researchers across academia, healthcare, and industry, and span genomics, transcriptomics, metagenomics, molecular interactions, chemistry, and functional annotation.
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.
The GNOME Foundation is a non-profit organization that believes in a world where everyone is empowered by technology they can trust. We do this by building a diverse and sustainable free software personal computing ecosystem.
Faust (Functional Audio Stream) is a functional programming language for sound synthesis and audio processing with a strong focus on the design of synthesizers, musical instruments, audio effects, etc. Faust targets high-performance signal processing applications and audio plug-ins for a variety of platforms and standards.
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.
JBoss Community is a community of open source projects. The community hosts a diverse set of projects that are written in various programming languages. The primary language is Java, however there are also projects that are written in Go, Rust, Ruby, PHP, Node and other languages.
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.
LibreCube develops an ecosystem of open source space technology for exploration systems.
Open, secure, decentralised communication
The MetaBrainz Foundation is a non-profit that believes in free, open access to data. It has been set up to build community maintained databases and make them available in the public domain or under Creative Commons licenses.
When working with different technologies and developers of different programming languages, the productivity of the entire team worsens due to the lack of interoperability and communication between them. If the developers need two technologies which are written in different programming languages, for instance, a C/C++ library called from NodeJS, the team usually needs to port to one of the two languages or write a wrapper around them. Maintaining a port of a library or the plumbing code is frequently error-prone, time-consuming, and does not add any value to the final product.
Confederation of microkernel projects (Genode, HelenOS, GNU Hurd, MINIX, Redox)
mofa-org is an open-source organization that builds and maintains the MoFA ecosystem — a modular AI agent framework that makes it easy to build, compose, and run complex AI applications & a collection of open-source tools and frameworks designed to:
