Claude Code is now natively integrated into Eclipse Theia and more.

In early November 2025, the Eclipse Foundation Security Team delivered the second part of our security training for developers for the second time. This part included updates from the first time we delivered the training in June.

CrossModel demonstrates a unified modeling experience built on Eclipse Theia, combining form-based, graphical, and textual editors, all synchronised via a language server.

As both a sponsor and active participant in the Adoptium Working Group, OpenElements demonstrates how even small teams can make a meaningful impact on open source sustainability.

Project context files are the secret to reliable, efficient AI coding. Learn 3 proven ways to make them more effective, and turn AI from a guessing game into a productive teammate. In the AI-native Theia IDE and any other tool such as Copilot, Claude Code, Cursor, and more.

The conference focuses on presenting new and unique results in the field of mobility simulation and modelling using openly available tools and data. We expect a large variety of research topics and usage approaches. Possible areas of interest include (but are not limited to):

The TheiaCon 2025 keynote provides a comprehensive update on a breakthrough year for the Eclipse Theia ecosystem, including major AI, platform, and architecture enhancements. A great overview for anyone interested in modern, open, AI-native tooling. The recording is now available!

This white paper outlines what open source stewards need to understand about their obligations, what processes may need to evolve, and where more discussion is needed.

Running a successful open source project requires investment, clear goals, and adherence to core principles like transparency, openness, and meritocracy.

Code editors are up for grabs, and the Eclipse Foundation is supporting this innovation and choice.

For the Theia community, this is a meaningful milestone. It confirms something many of us already felt simply by watching adoption: this project is becoming one of the most exciting developments in the open source dev tooling landscape!

The “Open Source Stewards and the Cyber Resilience Act” white paper explores a new role introduced by the EU Cyber Resilience Act (CRA): the open source steward. This is a newly introduced actor that doesn’t fit neatly into the existing categories of manufacturers or distributors but still carries specific obligations under the CRA.

November 12th, 2025 — The Eclipse Safe Open Vehicle Core (S-CORE) project today announced the active participation of Qualcomm Technologies, Inc. as a new member of its open source community. By leveraging Qualcomm Technologies Inc.’s Snapdragon® Digital Chassis™ solutions, S-CORE will run seamlessly on Qualcomm Technologies’ established high-performance hardware for future software-defined vehicles (SDVs).

We are happy to announce the release of SUMO version 1.25.0. The download links are at https://sumo.dlr.de/Download.

This release brings new features for routing (preferences, thresholds) and makes it easier to build small road networks that can be extended later. It also fixes many bugs.

Eclipse Theia 1.66 delivers a feature-rich update with persistent AI chat sessions, slash commands, agent modes, and new GitHub and Project Info agents. It also brings significant debugging, UI, and API improvements. Check out the full announcement!

Join us in Brussels from 21–23 April 2026, and grab your early bird discount before 6 January. Don’t miss the chance to be part of the future of open collaboration.

This commitment will benefit multiple core services, including Open VSX Registry, the open source registry for Visual Studio Code extensions that powers AI-enabled development environments such as Kiro and other leading tools.

Bringing cross-domain expertise, Android integration know-how, and automation excellence to the open-source SDV ecosystem.

Across the Eclipse Foundation, an expanding ecosystem of projects is redefining what AI can do, with efforts that span developer tools, data governance, trustworthy model design, and intelligent agent orchestration.
