Hi @arunsathiya

Big question the performance difference between running GitHub Codespaces in a browser versus using it with the VS Code extension depends on several factors. Here's a breakdown to help you decide:

1. Codespaces on Browser

• Pros:
  • No local setup required; it runs entirely in the cloud.
  • Ideal for quick access on devices where VS Code isn't installed.
  • Lower resource usage on your local machine, as the workload remains in the cloud.
• Cons:
  • Browser performance can be affected by:
    • Multiple open tabs.
    • Browser memory management.
    • Limited integration with local development tools (e.g., debuggers, terminals).
  • May feel less responsive if your browser is under heavy load.

2. Codespaces on VS Code Extension

• Pros:
  • Leverages the power of the native VS Code application.
  • Seamless integration with local tools and extensions.
  • Often faster and more responsive, as VS Code handles rendering and interactions more efficiently than a browser.
• Cons:
  • Requires installing VS Code and the Codespaces extension.
  • Slightly higher resource usage on your local machine compared to the browser.

Important

If you're prioritizing quick access and minimal local setup, the browser option is convenient.

For heavy development work and a smoother experience, the VS Code extension is generally more performant due to better resource management and integration with local workflows.

Best regards, happy to help you in any way bro.

Performance is effectively the same in both cases since the compute runs on the remote Codespace. However, using VS Code with the extension typically provides a smoother and more responsive experience due to the native app environment, better extension support, and reduced browser overhead. The browser version is convenient for quick edits, but for full development workflows, VS Code desktop is generally the better choice.
