Atom vs Theia: What are the differences?

1. Integration with Git: Atom has a built-in Git integration, allowing users to easily manage version control within the editor. On the other hand, Theia relies on external Git extensions, providing flexibility but requiring additional setup for Git integration.

2. Extensibility: Atom has a vast library of plugins and themes available through its package manager, making it highly customizable. Conversely, Theia has a more limited selection of extensions, with a focus on essential features to keep the workspace lightweight.

3. Collaborative Editing: Theia supports collaborative editing features out of the box, enabling multiple users to work on the same file simultaneously. Atom lacks native support for real-time collaborative editing, although some third-party packages can add this functionality.

4. Language Support: Atom has strong support for a wide range of programming languages and frameworks, making it suitable for diverse development environments. Theia, while also versatile, may require additional extensions to provide the same level of language support as Atom.

5. Resource Utilization: Theia is designed to be more lightweight and resource-efficient compared to Atom, making it a better choice for users working on less powerful machines or needing to run multiple instances simultaneously.

6. Workspace Management: Atom provides a more traditional single-user workspace environment, while Theia offers better support for multi-user and cloud-based development environments, making it more suitable for collaborative projects.

In Summary, Atom and Theia differ in Git integration, extensibility, collaborative editing, language support, resource utilization, and workspace management.
