Private bookmark sync

Different browsers.
One private vault.

Relay keeps Chrome, Brave, Edge, and other supported Chromium browsers aligned through one end-to-end encrypted vault. Chrome is public, the separate Edge package is in Partner Center setup, and Firefox Desktop is ready and awaiting Mozilla review. No email account. No readable cloud copy.

One glance, one decision

A sync tool should tell you what matters now.

Relay changes its first screen with the state of this browser. When everything is safe, there is nothing to press. When attention is needed, one clear action leads.

01

Current

See which profile is active, how many bookmarks are protected, and when Relay last checked.

No action
02

Changes found

Review what will be added or kept before Relay changes the local bookmark tree.

03

Libraries differ

Keep the local set as a new profile when a large difference looks intentional.

Save first

Sign in

Your Relay name finds the right vault. Nothing more.

Enter the username you chose, then continue. Relay shows the sign-in method available in this browser without making you guess.

  • The password saved in your Recovery Kit works in every supported Relay client.
  • Compatible Chromium browsers can also use an optional passkey.
  • Relay never receives biometric information or your vault password.
Actual sign-inChromium build
Relay sign-in asks for a Relay username first, with one prominent Continue action.

Add a browser

No exports. No blind merge.

Install Relay in another supported browser, sign into the same vault, and review both bookmark sets before anything changes. The separate Edge listing is in preparation; Firefox Desktop is awaiting Mozilla review.

  1. InstallOpen Relay in the second browser.
  2. Sign inUse your Relay name and Recovery Kit password. Compatible Chromium browsers can also use a passkey.
  3. ReviewChoose how the two libraries should come together.

Relay's Add browser screen explains installation, sign-in, and review in three steps.

Profiles

One vault can hold more than one version of your life.

Keep work, personal, client, or research libraries separate. Switch intentionally, archive old sets, and save the current browser before a large sync.

The trust boundary

The browser understands your bookmarks. Relay's service does not.

Bookmark titles, URLs, folders, profiles, and restore history are encrypted locally before upload. The service receives ciphertext and the limited metadata needed to operate your vault.
