RelayGitHub

Open source · macOS 13+

Open every link in the right space.

Relay sends each web link straight to the Chrome, Edge, or Firefox profile where it belongs—Personal, Work, Research, or wherever you browse.

Built around your spaces

Your browsing life, neatly separated.

Give each browser profile a memorable space, then connect the sites you use to the place where they already belong.

Profiles keep their own accounts, sessions, and browsing state.

The idea is simple

Set the route once. Click without thinking.

Relay turns browser profiles into destinations, then quietly matches each link to the most specific rule. You keep clicking links the way you always have.

Small app, sharp decisions

Quiet on the surface. Precise underneath.

Relay stays out of your way because it is deliberate about the details—rule priority, stable profile identity, and the final browser launch.

01

Profiles don’t drift

Relay targets the browser and profile directory—not a display name that can change underneath you.

02

No routing loops

The chosen browser launches directly with its profile argument, so the link never bounces back to Relay.

03

Human when needed

Use a fallback for the obvious cases. When there isn’t one, Relay asks instead of guessing.

For keyboard people

Relay works from Terminal, too.

Inspect profiles, preview a route, open a link, or diagnose your setup with the bundled command-line tool.

Private by design

A routing history—not a browsing history.

Relay keeps only what it needs to explain where a link went: the normalized domain, destination, outcome, reason, and timestamp. Everything stays on your Mac.
