+TheiaCon is a virtual conference focused around the Eclipse Theia IDE ecosystem. It brings together a diverse group of Theia developers, adopters, and other contributors. The program will feature a mix of full-length talks, expert panel discussions and short ”lightning talks” focused on project insider, adopter stories, and broader ecosystem. This event is hosted by the Eclipse Foundation’s Cloud DevTools Working Group and is open to anyone interested in learning more about Cloud IDE development and the Theia project.
