Browser extension

Buddy browser integrations for Chrome and Firefox

Autofill without putting a second vault in your browser. The extension asks the Buddy desktop app for credentials over your operating system's local native-messaging channel.

Not published yet. The extension is in final testing and is not in the Chrome Web Store or on addons.mozilla.org today. Buddy for desktop is finished and available now, and the extension arrives as a free update to it. Watch the release notes for the announcement.

Chrome

Also works in Edge, Brave, Arc and other Chromium browsers.

Coming soon

Firefox

Requires Firefox 112 or later.

Built for the messy web, not a perfect demo form

Login forms vary wildly across sites and frameworks. Buddy groups related inputs and scores several signals instead of betting your credentials on one label or autocomplete attribute.

It is tested against captured fixtures for ordinary forms, multi-step logins, formless applications, registration pages, hidden decoys, and TOTP steps. In practice:

Desktop-initiated fill

Launch a site from the desktop app in one click and it's filled automatically.

Extension-initiated fill

Click on a login form, and Buddy will check for matching entries based on the current page URL.

Multi-page fill sessions

Sign-in flows that ask for your username first and your password on the next screen are treated as one session, so the second page picks up where the first left off instead of making you start over.

Single-use fill tokens

A fill session holds a single-use token, rotated every time it's redeemed. Secrets are only fetched at the moment of fill and aren't long-lived.

Fields are scored, not guessed

Inputs are grouped by their form, or by their nearest shared ancestor for the formless kind that modern frameworks produce, then ranked on weighted signals rather than one hopeful label match.

Offers to save new logins

Sign up somewhere and Buddy offers to keep it, picking up the site's icon along the way. If you have more than one vault open, you choose where it lands.

You need the desktop app too

The extension has no vault of its own. It asks the Buddy desktop app for a match on the page you're viewing, and the app answers only while the vault is unlocked. The first time a browser connects, the desktop app asks you to approve it, and you can revoke that approval at any time under Settings → Browser Extension.
