Already using ManicTime? This extension is not for you. The ManicTime desktop app tracks your whole device (apps, documents, browser, idle time) more accurately and is the better tool. Browser Time Tracker is a free, separate, smaller product for people who do not use ManicTime and only want browser tracking inside Chrome.
If most of your work happens in tabs — email, docs, project tools, dashboards, support, research — explaining where the day went is hard. Browser history is too noisy and manual timers are easy to forget.
Browser Time Tracker is a free Chrome extension that records browser activity automatically, lets you tag it, and turns it into timesheets. Install it from the Chrome Web Store — no account needed.
What it does
- Records visited pages, titles, and durations on a timeline
- Distinguishes active time from idle time
- Lets you tag blocks of time by client, project, or task
- Generates timesheets and exports to CSV
- Provides analytics by website and page
- Lets you search across tracked browser activity
It tracks browser activity only. Apps, documents, meetings, and offline work are out of scope — for that, use a desktop tracker like ManicTime.
Tag once, when you are ready
You do not start a timer. The extension runs quietly; when you want to account for time, open it, select a block on the timeline, and tag it:
Client A, Website redesign, HomepageSupport, Customer emailsResearch, Competitor review
To see a summary of your work, open the Timesheet view and export it when you need to bill or report.
Local-first and private
Tracking data — URLs, page titles, visit times, tags, settings — stays in Chrome's local storage on your device. Nothing is sent to ManicTime servers or any cloud service.
The extension uses only the permissions it needs: history, tabs, idle, storage, alarms, and favicon. See the privacy policy for details.
Accuracy: what to expect
Browser Time Tracker only sees activity inside Chrome. It can detect browser activity and idle state, but it cannot see what you do in other apps, documents, meetings, phone calls, or offline work. That means it is useful for understanding browser time, but it should not be treated as a complete or audit-grade record of your workday. If you need accurate active/away tracking across your whole computer, use ManicTime.
Who it is for
If you spend most of your day in Chrome, or you simply want to see where your browser time goes, this extension is for you.
Install Browser Time Tracker and let it run for a few days. You will have a record of your browser time that you can tag and export as a timesheet — without signing up for anything.
