Is there a browser-sync option to open Google Chrome in incognito mode?
Chrome's command line switch is actually --incognito (two dashes), but I tried it in my browsersync Gulp task and that didn't work.
The workaround I'm using is to use a Chrome extension to switch my development domain name to incognito. It looks like there are a couple extensions that do that, I use Ghost Incognito:https://chrome.google.com/webstore/detail/ghost-incognito/gedeaafllmnkkgbinfnleblcglamgebg?hl=en-US
