🌉 Viaduct — Run Chrome Extensions in Safari on macOS

Viaduct is a powerful macOS utility that makes it easy to bring Chrome extensions into Safari. It converts Chrome extensions into Safari-compatible web extensions, handles the signing and installation process, and removes much of the technical complexity normally involved in converting extensions manually.

Whether you rely on a favorite Chrome extension that's unavailable in Safari, want to switch to Safari without losing essential browser tools, or simply want a simpler way to experiment with extensions, Viaduct provides a streamlined solution.

🧩 Convert Chrome Extensions to Safari

Turn Chrome extensions into Safari-compatible extensions without manually creating and configuring an Xcode project.

⚡ One-Click Conversion Workflow

Drag in an extension or provide a Chrome Web Store link and let Viaduct handle the conversion process automatically.

🌐 Bring Chrome Web Store Extensions to Safari

Access extensions that were originally designed for Chrome while continuing to use Safari as your primary browser.

🔐 Handle Extension Signing

Simplify the signing and installation process so you don't have to manually deal with certificates, packaging, and complicated development workflows.

🔄 Keep Extensions Working

Viaduct can automatically renew converted extensions, helping avoid the expiration issues that can occur with manually self-signed Safari extensions.

🛠️ Handle Compatibility Challenges

Its conversion engine includes compatibility support for Chrome extension APIs that don't have direct equivalents in Safari, helping more complex extensions work correctly.

🚀 Skip Xcode & Terminal Workflows

Avoid manually running conversion commands, editing manifests, moving files, and configuring Safari development settings just to install an extension.

🧼 Clean & Focused macOS Experience

Designed for Mac with a streamlined interface that turns a traditionally technical process into a simple desktop workflow.
