Drag a tab out of Chrome and get an instant colour-coded tab group
Drag a tab into a new window and a coloured, titled group appears — zero clicks.
How does drag-out auto-grouping work?
Direct answer
Flocci Tabs listens for Chrome’s window-creation event. The moment you drag a tab out into its own window, the extension creates a tab group around it, titles the group from the page, and assigns a colour that is not already in use nearby — all before you let go of the mouse. No menu, no right-click, no setup.
What it does
- Fires on the gesture you already make — dragging a tab to a second monitor or a side-by-side window.
- Titles the group from the tab, so the group is labelled before you have typed anything.
- Picks a colour by domain hint first, then by rotation, so two live groups rarely collide.
- Detects title conflicts with existing groups and queues a rename instead of shipping two identical labels.
Under the hood
Implemented on chrome.windows.onCreated in the MV3 service worker, with a debounce so a burst of window events does not create duplicate groups.

Drag-out auto-grouping — questions
Straight answers, no marketing detours.
Does drag-out auto-grouping need a Flocci account?
No. This runs entirely on your device and works the moment the extension is installed. No sign-in, no account, no network call.
Can I turn drag-out auto-grouping off?
Yes. Every behaviour is toggleable from the extension's options page, and rules, colours and keyword filters can be rewritten or exported as JSON for backup.
What exactly leaves my browser?
Nothing. This feature is local-only — it uses Chrome's tabs and tabGroups APIs on your machine and makes no network request at all.
Try drag-out auto-grouping yourself
Install once, then drag a tab out. That is the setup.
No account needed for automatic grouping. No API key, ever.
