LinkRouter is a Mac utility for people who keep work and personal sessions in different browsers, Chrome profiles, and Gmail accounts. Click a link in Slack, Mail, or Notes and a picker appears at the cursor, listing every installed browser, each Chrome, Brave, Chromium, and Firefox-family profile, and each signed-in Google account. Press a number and the link opens in that session. The same picker handles email. Choose a Google account and Gmail compose opens inside the Chrome profile that owns it, with the recipient, subject, and body filled in. Apple Mail and other mail apps are on the picker too, along with an option to copy the address. Hold Command while you pick and LinkRouter saves a rule for that website, source app, or email domain, so the next match opens without asking. Hold Option to bring the picker back. Before anything opens, it unwraps Outlook Safe Links and Google or Slack redirects, and it strips tracking parameters. A tab that still lands in the wrong profile can be moved with Control-Option-B. Ahmed Gagan, the independent developer who runs Snugbits, built LinkRouter after Slack links kept opening in the wrong Chrome profile and email links kept opening Apple Mail. It requires macOS 14 or later, stays on the machine with no account and no cloud, and is a one-time license at $5 for one Mac, $10 for three, or $15 for five. Quit the app and links fall back to the previous default browser.
