The Eclipse Foundation just released version 1.0 of an open-source alternative to Visual Studio Code called Eclipse Theia. Theia is an extensible platform that allows developers to create multi-language cloud and desktop IDEs, allowing them to create entirely new developer experiences.

According to the Eclipse Foundation, the differences between Theia and Visual Studio Code are that Theia has a more modular architecture, Theia was designed from the ground to run on desktop and cloud, and Theia was developed under community-driven and vendor-neutral governance of the Eclipse Foundation. 

The Theia project was started by Ericsson and TypeFox in 2016, and since then it has become an integral part of cloud solutions globally. The project approached the Eclipse Foundation about becoming a potential host in 2019. 

Early contributors to the project include ARM, Arduino, EclipseSource, Ericsson, Google Cloud, IBM, Red Hat, SAP, and TypeFox. Within the Eclipse Foundation, Theia is a part of the Eclipse Cloud Development Tools Working Group. 

“We are thrilled to see Eclipse Theia deliver on its promise of providing a production-ready, vendor-neutral, and open source framework for creating custom and white-labeled developer products,” said Mike Milinkovich, executive director of the Eclipse Foundation. “Visual Studio Code is one of the world’s most popular development environments. Not only does Theia allow developers to install and reuse VS Code extensions, it provides an extensible and adaptable platform that can be tailored to specific use cases, which is a huge benefit for any organization that wants to deliver a modern and professional development experience. Congratulations to all the Theia committers and contributors on achieving this milestone.”
