AI is rapidly becoming a default capability in developer tools, but many teams still face the same constraints: vendor lock in, limited transparency, and the inability to run AI in restricted environments.
In this session, you will see a live demo of Eclipse Theia and Theia AI, an open source platform and framework to build AI-enabled developer tools: IDEs, domain specific environments, code-centric workbenches, and cloud or desktop applications embedding editing, navigation, and automation workflows. Unlike closed solutions, Theia AI is designed to be extensible and provider-independent. You can integrate chat, completions, and agent-like workflows while keeping full control over how models are connected and what data is shared.
The demo runs in a fully air gapped setup using local LLMs only, demonstrating AI-assisted coding and navigation without sending prompts or source code to external services. We will also show how Open VSX, the Eclipse Foundation’s open source extension registry, enables distribution and reuse of extensions, turning Theia from a framework into a practical foundation for products and internal tooling.
You will leave with a clear architectural understanding of how to embed AI capabilities into developer tools that can fit both open innovation and enterprise constraints.
