# Experimental Features JS Check - Do not use Chromium’s experimental features

The experimentalFeatures and experimentalCanvasFeatures flags can be used to enable Chromium’s experimental features, which increase the overall attack surface for production applications.

#Risk

Experimental features may introduce bugs and increase the application attack surface.

#Auditing

Search for experimentalFeatures and experimentalCanvasFeatures flags set to true within the webPreferences of BrowserWindow:

        mainWindow = new BrowserWindow({
  webPreferences: {
    experimentalCanvasFeatures: true
  }
});
