Cursor Extension Integration
Integrate VS Code extensions with Cursor IDE. Covers the Open VSX Registry, VSIX installation for Microsoft-exclusive extensions, conflict resolution with AI features, and recommended extension stacks.
Extension Marketplace: Key Difference from VS Code
Cursor uses the Open VSX Registry instead of Microsoft's VS Code Marketplace. This is because Microsoft's marketplace terms restrict access to VS Code products only.
Impact: Most popular extensions are on Open VSX. Some Microsoft-published extensions are not.
Available on Open VSX (works directly)
Extension Category ESLint Linting Prettier Formatting GitLens Git visualization Docker Container management Python Python language support Pylance Python analysis (community build) Go Go language support Rust Analyzer Rust language support Tailwind CSS IntelliSense CSS utilities Auto Rename Tag
Error Lens Inline error display

Installing Extensions
From Open VSX (In-App) Cmd+Shift+X → search extension name → Install
From VSIX (Manual) For extensions not on Open VSX:
Go to the VS Code Marketplace website: marketplace.visualstudio.com
Find the extension page
Click "Download Extension" (downloads .vsix file)
In Cursor: Cmd+Shift+P > Extensions: Install from VSIX...
Select the downloaded .vsix file
From Command Line # Install from Open VSX
cursor --install-extension dbaeumer.vscode-eslint
# Install from VSIX file
cursor --install-extension ~/Downloads/extension.vsix
# List installed extensions
cursor --list-extensions
# Uninstall
cursor --uninstall-extension dbaeumer.vscode-eslint
Conflict Resolution with Cursor AI
Extensions That Conflict with Cursor Extension Conflict Resolution GitHub Copilot Duplicate Tab/ghost text suggestions Disable Copilot. Cursor's built-in AI is better integrated TabNine Duplicate inline completions Disable TabNine Codeium Duplicate inline completions Disable Codeium IntelliCode Duplicate completions Disable IntelliCode Vim Ctrl+K/L/I keybinding conflicts Remap AI shortcuts (see below)
Vim Extension Conflict Resolution // keybindings.json

General Keybinding Conflict Check Cmd+K Cmd+S > search for the conflicting shortcut > see which commands are bound > reassign or disable.

Performance Impact Extensions affect editor performance. Audit regularly:
Measuring Extension Impact
Cmd+Shift+P > Developer: Show Running ExtensionsSort by activation time or profile time
Disable extensions with high activation times that you rarely use
Common Performance Offenders Extension Issue Fix GitLens High CPU on large repos Disable for repos > 100K commits Prettier (on save) Slow on large files Configure file size limit TypeScript High memory on large projects Increase tsserver.maxTsServerMemory Spell checker CPU on large files Exclude generated files
Disabling Extensions Per Workspace // .vscode/settings.json (per project)
{
"extensions.ignoreRecommendations": true
}
Or right-click an extension > Disable (Workspace) to disable only for the current project.
Extension Settings Sync Cursor does not sync extensions between machines automatically like VS Code Settings Sync. To transfer:
# Export extension list
cursor --list-extensions > cursor-extensions.txt
# On new machine, reinstall all
while read ext; do cursor --install-extension "$ext"; done < cursor-extensions.txt
Enterprise Considerations
Extension allow/deny lists : No built-in mechanism in Cursor. Enforce via documentation and team policy.VSIX vetting : Review VSIX files before distributing to team (check for telemetry, network calls)Open VSX vs Marketplace : Some extensions have different publishers on Open VSX. Verify publisher identity.Extension updates : Extensions auto-update from Open VSX. VSIX-installed extensions do NOT auto-update.
