👋 We are TypeFox – a team of software pioneers based in Kiel, northern Germany. We create and maintain open source tools, libraries, and frameworks, and support our customers in turning these building blocks into tailored, production-ready solutions.

These are the main open source projects that we have founded and are actively maintaining:

Langium – build powerful domain-specific languages (DSLs) with ease
Theia – create custom, web-based IDEs on a VS Code–like foundation
Open Collaboration Tools – integrate real-time collaborative editing into IDEs and web apps
Sprotty – render interactive diagrams to visualize models and data

Our GitHub organization is where new ideas take shape—explore more projects and contributions here.
