The WakaTime plugin works with Google Chrome Browser and is open-source on GitHub.
The Chrome extension shows the time you spend reading documentation, debugging a web app, and other browser based activity.
The Chrome extension is still a work-in-progress, and may not play nice with your other editor-based WakaTime plugins.
Activity from this Chrome extension will not display on leaderboards, so installing this extension may lower your rank.
Install the Chrome Extension:
Login to WakaTime.
Use Chrome like normal and your time will be tracked automatically on your https://wakatime.com/dashboard.
