Kobra.io vs Theia: What are the differences?
What is Kobra.io? Collaborative "Google Docs" for code. Kobra is the easiest way to collaborate on code quickly with your coworkers, friends or students. With built in video & voice chat, the themes and keyboard shortcuts you're used to and syntax highlighting, you'll feel right at home. We're not trying to be your online IDE, we just want to be the simple online editor you use to collaborate on the fly.
What is Theia? Cloud & desktop IDE framework implemented in TypeScript. Theia provides the end-user with a full-fledged multi-language IDE (not just a smart editor) and supports equally the paradigm of Cloud IDE and Desktop IDE.
Kobra.io and Theia can be primarily classified as "Cloud IDE" tools.
Theia is an open source tool with 4.66K GitHub stars and 584 GitHub forks. Here's a link to Theia's open source repository on GitHub.
