GRAVITI RELAYmacOS v1.4GRAVITI Relay is a Mac and Windows app that receives links from your system and lets you choose an installed browser. It is not a browser itself.
Free to download·macOS + Windows
Select a browser and opening options.
This is a simulation. No browser will open.
01 / One-time setup
Use the notarized macOS app or per-user Windows installer. No extra runtime.

Your operating system asks you to confirm the default HTTP/HTTPS handler.
03 / Open
When a link arrives, choose a browser, profile, or private mode, then continue.
02 — Compatibility
17 app languagesRelay shows only browsers installed on your computer and routes the link to the one you choose. It discovers profiles read-only from Google Chrome, Microsoft Edge, Brave, Comet, and Firefox. Safari opens links normally, but offers no public API for third-party profile or Private Window selection.
03 — Privacy
Browser selection and profile discovery happen locally on your device. GRAVITI RELAY reads only the profile metadata needed to list destinations, read-only, and does not upload routed URLs or browser/profile data to Graviti. It has no analytics, advertising, tracking, telemetry, or crash uploads. The app contacts graviti.day to check its release manifest without attaching routed links or profile names to that request.
Private mode separates a session. It is not a malware scanner, anonymity tool, or replacement for antivirus.

macOS v1.4 · Windows / Microsoft Store05 — FAQ
The apps are packaged differently. macOS uses Swift and system frameworks. Windows bundles the .NET runtime and required libraries, so you do not need to install .NET separately. Architecture and compression affect size, and installed space shown in Store may differ from download size.
Windows is free exclusively through Microsoft Store, which delivers a digitally signed package and manages installation and updates. This website does not distribute direct Windows installers. macOS uses a Developer ID-signed, notarized DMG with SHA-256 to check the file.
Yes. The operating system must send HTTP/HTTPS links to Relay first, and asks you to confirm that change.
No. It reads profile metadata read-only and does not read history, cookies, passwords, bookmarks, or page content.
Safari exposes no public API for an outside app to read or select profiles. Relay does not inspect Safari UI or guess which profile is active.
Safari has no supported public API for opening a Private Window with a URL from another app. UI automation would require Accessibility and could target the wrong window.
No. The current Direct build does not request Accessibility, Automation, or Full Disk Access.
The macOS release is signed with an Apple Developer ID and notarized for distribution outside the Mac App Store. Gatekeeper can verify its signature and ticket; this is not an Apple endorsement.
Browser names belong to their respective owners and describe compatibility only. GRAVITI Relay is an independent product, not endorsed by those owners.
