TabStyr

About

TabStyr shows where your browser time actually goes — and keeps every byte of it on your own device.

It quietly measures the time you spend actively on each tab and website, then presents it as a clear, private dashboard: trends, an activity heatmap, focus scoring, category breakdowns, and gentle reminders for the tabs you've left behind. No account, no servers, and no data ever leaves your machine.

FEATURES

• Today at a glance — active time versus your weekly average, with a sparkline.
• Trends — day, week, and month views.
• Activity heatmap — the hours and days you browse most.
• Categories — time grouped into Work, Dev, Finance, Social, Media, News, and Shopping, with hundreds of sites recognized automatically. Reclassify any site or add your own rules.
• Focus score — a daily productive-versus-distracting percentage, with a streak.
• Top sites and per-tab breakdown — with a detail view for any site.
• Daily work log — pick a day and copy a clean list of sites for standups or invoices.
• Stale-tab reminders — a badge count and an optional once-a-day nudge.
• Comparisons — week-over-week and month-over-month, with per-category deltas.
• Export and encrypted backup — download your full history as JSON, optionally passphrase-encrypted, and restore it on any device.

PRIVACY

TabStyr is private by default:

• 100% local. All data is stored in your browser (IndexedDB) and automatically pruned to a rolling 90-day window.
• No servers, no accounts, no analytics, and no ads. The extension makes no automated network requests.
• It never reads page content — only the URL and title of the focused tab, which the browser already provides.
• Your data stays yours: export it, encrypt it, or erase everything in a single click. There is no cloud and no backend to upload to.

COMPATIBILITY

Works on Chrome and other Chromium-based browsers. Available in 11 languages.
