Tabby Sitter - Automated Tab Manager

Tracking since May 4, 2026.

Changelog

• Jun 9, 2026
  description

  Tired of hunting through a sea of identical tabs to find the right one? Tabby Sitter watches your browsing and automatically sorts tabs into named, color-coded groups the moment they open. This works really well with vertical tabs (go to chrome://flags and enable vertical tabs).
  
  Define simple keyword rules or use regex — your tabs stay organized without lifting a finger.
  
  Note: This works best when you use "Vertical Tabs". To turn on Vertical Tabs, enable it in chrome://flags (if required) and then in Settings --> Appearance set tabs to "Vertical".
  
  Why you'll love it:
  
  - Set it and forget it. Create grouping rules once (e.g. all tabs containing "github.com" → "Dev") and every matching tab lands in the right group automatically. No manual dragging, ever.
  
  - Regex power when you need it. Keyword matching works for most sites, but regex is there if you need precision — match parts of URLs, file extensions, query parameters, whatever.
  
  - One shortcut to rule them all. Hit Ctrl+Shift+O (or Cmd+Shift+O on Mac) to organize every tab in your current window instantly.
  
  - Full control over your rules. Enable or disable rules without deleting them, reorder them with arrow buttons, edit inline, and get a confirm prompt before removal so you never accidentally wipe a rule.
  
  - Rules travel with you. Export your rules to a JSON config file, drop it in Dropbox or iCloud, and import it on another machine. Merge mode means you can combine configs without overwriting.
  
  - Sort the stragglers. Tabs that don't match any rule get sorted alphabetically by domain so the leftovers are at least tidy.
  
  - Privacy-first. Everything lives in your local Chrome storage. No accounts, no analytics, no network requests. The extension is open source and has zero runtime dependencies.
  
  Perfect for:
  
  - Developers juggling docs, repositories, and dashboards
  - Researchers managing multiple sources
  - Anyone with more than 20 tabs who's tired of the chaos
  
  Lightweight. Under 50 KB zipped. No tracking. No bloat. Just organized tabs.

  New in 0.6.0 --> Keep a watch for duplicate tabs and have a confirmation. Great for continously opening up the same git pull request inside of Claude / Gemini / OpenCode CLIs for example!
