Turn the page you are reading into a branded, UTM-tagged shortlink without leaving the tab. The free Attr.so extension lives in your toolbar and connects to your account automatically.
Three small jobs the extension does well, so you never have to leave the tab you are reading.
Click the toolbar button. The current tab URL becomes a branded shortlink under your default custom domain - no copy-paste, no tab switch, no dashboard round-trip.
The popup pre-fills your default UTM source, medium, and campaign so every quick share is attributed to the right channel automatically. Override the values for one-off links without leaving the popup.
Click the button, click Copy. The shortlink is on your clipboard and live in your Attr.so dashboard, with click analytics already running. That is the entire workflow.
We resisted the urge to cram a full dashboard into a 380-pixel popup. Every field has a job.
Live connection to your Attr.so account. Green dot means signed in and ready.
Pre-filled from the current tab. Editable for one-off changes.
Generated under your default custom domain. Click Copy and it is live.
Auto-filled from your presets. Click any chip to override for this link.
Hit ⌘ + L from any page to open the popup without reaching for the mouse.
About 90 seconds end-to-end, including signing in. No dashboard round-trip after that.
Add the free Attr.so extension to Chrome - or any Chromium-based browser. Edge, Brave, Arc, Opera and Vivaldi all work.
Open the extension and sign in with your Attr.so account. We pick up your default custom domain and UTM presets automatically.
Visit any page, click the toolbar button, click Copy. The shortlink is on your clipboard and tracking from the first visitor.
The boring, repeatable promises. The same posture as the rest of the platform.
The extension only reads the current tab URL at the moment you click the toolbar button. No background reading, no keystroke logging, no cross-site tracking.
Visitors who follow your shortlinks land on the destination URL with zero cookies dropped and zero third-party scripts loaded. Same privacy posture as the rest of the platform.
Your auth token is cached in chrome.storage on your device only. It is sent to our API to authenticate your own requests; it is never broadcast or synced through any third party.
Manifest v3. Both permissions are listed in the Chrome Web Store entry.
Built on Manifest v3, so any Chromium-based browser runs the extension as-is.
