VSCodium/WindSurf/Cursor support

[matifali]

Coder’s current VS Code extension relies on ms-vscode-remote.remote-ssh, which is only available via the Microsoft Marketplace. This limits compatibility with non-Microsoft VS Code forks such as VSCodium, Cursor IDE, and Windsurf, which cannot access the Microsoft Marketplace. Users in air-gapped or privacy-focused environments need a version of the Coder extension that works without this dependency.

Desired Solution

• Create a Coder extension variant that is compatible with VSCodium, Cursor IDE, Windsurf, and other VS Code forks by using an open-source SSH extension such as jeanp413.open-remote-ssh.
• Publish this extension on Open VSX for easy access.
• Create terraform modules for these editors, similar to the existing VS Code Desktop module.

Implementation Requirements

• Extension Development:
  • Remove reliance on ms-vscode-remote.remote-ssh in vscode-coder internal#430
• Marketplace Deployment:
  • Publish vscode-coder extension on Open VSX internal#431
• Terraform Modules:
  • VSCodium - Create VSCodium coder module internal#432
  • Windsurf - Create Windsurf Coder module internal#433
    • Existing PR: Add Windsurf Desktop module modules#353
• Documentation:
  • Document how to use vscode-coder using OpenVSX internal#434

Related Issues:

• Feature Request: VSCodium support coder#15846
• Remote SSH access from VSCodium VSCodium/vscodium#693
• Add Windsurf Desktop module modules#353

@code-asher We have now requests for VSCodium, Windsurf and a buggy behavior on Cursor too.
We may need to ship a new separate binary without relying on the MS remote SSh extension as it only works on the MS version of VSCode.

Discussed in coder/coder#15846

^{Originally posted by asgeirn December 12, 2024}
We're investigating using Coder in an isolated environment with no Internet connectivity, and according to the documentation for offline deployment, VSCode requires outbound port 443 access for the remote SSH extension to work.

I tried installing the Coder VSIX in VSCodium, but it fails because it depends on the ms-vscode-remote.remote-ssh extension. According to VSCodium/vscodium#693 the extension 'jeanp413.open-remote-ssh' does this.

Would it be possible to provide a variant of the Codium extension on Open VSX for this, and a module for creating "Open in VSCodium" links in workspaces?

WindSurf does not use both Microsoft SSH and Open Remote SSH extensions and has its own built-in implementation.
