VSCode Custom Startpage

Minimal VS Code extension that opens a configurable remote URL in a webview tab on startup. It does not replace the built-in Welcome editor; it opens its own tab in the editor area.

Features

• Opens a webview tab on startup or when a command is run.
• Loads a single configured URL.
• Restricts webview navigation to the configured origin via CSP.

Settings

• customStartPage.url: Remote URL to load in the webview.
• customStartPage.openWhen: always or workspace.

Commands

• Custom Start Page: Open (customStartPage.open)

Usage

1. Set customStartPage.url in user settings.
2. Optionally set customStartPage.openWhen to workspace.
3. Restart VS Code or run the command to open the tab.

If you want the Welcome page hidden, set:

• workbench.startupEditor: none

Build

npm install
npm run compile

Package

npx vsce package

Limitations

• The remote site must allow embedding in an iframe (no restrictive X-Frame-Options or frame-ancestors).
