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.
Building platforms for reproducible AI Research
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.
Computer Vision Data Annotation Platform for AI
Data for the Common Good is dedicated to building communities, platforms, and ecosystems that maximize the potential of data to drive discovery and improve human health. Headquartered in the Department of Pediatrics at the University of Chicago, our team of experts works with collaborators all over the world to connect and share useful, high-quality data between institutions, groups, and countries to increase opportunities for discovery.
Django is a high-level Python Web framework originally developed at the Lawrence-Journal World. Django was designed to handle two challenges: the intensive deadlines of a newsroom and the stringent requirements of the experienced Web developers who wrote it. It lets you build high-performing, elegant Web applications quickly.

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.
Joplin is a note-taking app designed with strong security and privacy in mind. It features end-to-end encryption (E2EE), ensuring the notes remain protected during synchronization. Users can store notes locally or sync them via trusted services like Nextcloud, Dropbox, or self-hosted servers, retaining full data ownership.
Distributed version-control for geospatial data
Liquid Galaxy is a remarkable panoramic system that is tremendously compelling. It started off as a Google 20% project to run Google Earth across a small cluster of PC's and it has grown from there! Liquid Galaxy hardware consists of one or more computers driving multiple displays. Liquid Galaxy applications have been developed using a master/slave architecture. The view orientation of each slave display is configured in reference to the view of the master display. Navigation on the system is done from the master instance and the location on the master is broadcast to the slaves over UDP. The slave instances, knowing their own locations in reference to the master, then change their views accordingly. The Liquid Galaxy Project, while making use of Google Earth software, does not develop the Google Earth code-base itself. Google Earth is not open-source software, although it is free (as in beer). Instead, the Liquid Galaxy Project works on extending the Liquid Galaxy system with open-source software both improving its administration and enabling open-source applications, so that content of various types can be displayed in the immersive panoramic environment. Artificial Intelligence focus: 2026 is the year when AI is going to change the coding industry, and GSoC and the open-source projects on it, have to jump on. At the Liquid Galaxy community, we’ve been using AI for years to obtain data to be shown on Google Earth for our projects, using many models and technologies. This 2026, all the projects will have an Artificial Intelligence voice, and most of them will use of diferent AI models to handle queries and arrange data, starting from Google's Gemini and Gemma.
MariaDB Foundation is the non-profit organization behind MariaDB Server, the fastest growing open source databases. MariaDB Foundation's mission is to ensure the continuity of the MariaDB Server code as well as foster and facilitated collaboration within the MariaDB ecosystem. As part of GSoC, MariaDB Foundation seeks to bring more developers into the MariaDB Server (and related projects) code base.
Webapp providing a UX-first interface to databases
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.
The National Resource for Network Biology (NRNB, https://nrnb.org) organizes the development of free, open-source software technologies to enable network-based visualization, analysis, and biomedical discovery. Biomedical research is increasingly dependent on knowledge expressed in terms of networks, including gene, protein and drug interactions, cell-cell and viral-host communication, and vast social networks. Our technologies enable researchers to assemble and analyze these networks and to use them to better understand biological systems and, in particular, how they fail in disease. The NRNB mentoring organization includes projects such as Cytoscape (https://cytoscape.org/), WikiPathways (https://wikipathways.org/), SBML (https://sbml.org/), SBGN (https://sbgn.github.io/) and others. This is a great opportunity to work at the intersection of biology and computing! For example, Cytoscape is downloaded over 24,000 times per month by researchers. We take mentoring seriously and are proud of our 96% success rate (https://nrnb.org/alumni.html#gsoc-tab) with former students and projects. But don’t take our word for it, read testimonials from prior NRNB students (https://nrnb.org/testimonials.html#student-tab) and mentors (https://nrnb.org/testimonials.html#mentor-tab). Find out more about the software projects being developed in coordination with NRNB at our website (https://nrnb.org). Also refer to our GSoC page (https://nrnb.org/gsoc.html) for additional resources and application tips.
Open-Source Tools for 3D Genomics Research
Open Technologies Alliance (GFOSS) is a non-profit organization, with 37 Universities and Research Centers as its shareholders. Our main goal is to promote Openness. GFOSS – Open Technologies Alliance is a platform for Open Standards, Free Software, Open Content, Open Data & Open Hardware in Greece. The major Greek Universities and Research Centers participate in GFOSS – Open Technologies Alliance, while leading members of the Greek community of developers play a key role in the implementation of our policies. Through our initiatives we aspire to contribute and coordinate the efforts of groups of volunteers, public servants, university researchers and students enabling them to form the backbone of Greek FOSS development and implementation. GFOSS is one of the strategic actors for the promotion of OSS throughout Greece (see https://joinup.ec.europa.eu/sites/default/files/inline-files/OSS%20Country%20Intelligence%20Report_GR.pdf ). Many public administrations and academic institutions collaborate with GFOSS to implement open source projects and through Google Summer of Code we give the opportunity to students to actively engage in the production and the actual implementation of an open source project. GFOSS also contributes and advises on the development of various open source projects related to e-government and digital transformation in Greece (e.g. https://howto.gov.gr/ - https://forma.gov.gr/) and actively promotes the use of Open Source software and hardware in the Greek primary and secondary education through the Open Educational Technologies Competition (https://openedtech.ellak.gr/ )
