TheiaCon 2026

Building the future of open, AI-powered developer tools

Join the Eclipse Theia community for two days exploring the latest advances in developer tooling, with technical deep dives, real-world adopter stories, platform updates, and practical insights into integrating AI into modern development environments.

Virtual Event | 28-29 October 2026

About the Event

TheiaCon brings together developers, tool builders, software architects, platform engineers, and Eclipse Theia contributors from around the world.

TheiaCon 2026 will explore how developers are using Eclipse Theia to create the next generation of developer tools, from cloud and desktop IDEs to engineering platforms, domain-specific environments, and commercial products.

We are shaping a program that combines real-world engineering experiences, technical insights, open source innovation, and a look at what is next for the Theia platform. AI will be an important part of the conversation, including how Theia AI supports tailored AI-powered experiences and how the AI-powered Theia IDE brings those capabilities to developers.

Eclipse Theia will remain at the heart of the event. The program will also explore the technologies, projects, and communities that strengthen Theia-based development, including the wider Eclipse ecosystem, Eclipse Open VSX, and the evolving landscape of open, AI-powered developer tooling.
