Browser-only editors

vscode.dev and github.dev run the whole editor inside a browser tab. There is no Node process, no way to start a child process, and files come from a virtual filesystem.

The extension has a main (Node) entry point and no browser entry point, so these editors cannot load it at all. Nothing runs: no findings, no status bar item, no commands.

What to do instead

• On a GitHub repository page, press . to open github.dev, then Continue Working On… to move into a Codespace or a local clone. Both have a filesystem and run the extension.
• For a browser UI with a real extension host, use code-server, OpenVSCode Server, Gitpod, Coder or Firebase Studio: Remote workspaces and containers.
• To look up a vulnerability identifier on any web page, use the browser extension.
