About Viaduct

Viaduct is a macOS application that converts Chrome extensions into native Safari Web Extensions without requiring manual coding or terminal commands.

Key Features
  • Direct Conversion: Converts .crx files, .zip archives, unpacked folders, and Manifest V2/V3 extensions into signed Safari Web Extensions.
  • Compatibility Layer: Includes a built-in runtime layer normalizing over 47 chrome.* API namespaces to fix common Safari incompatibilities (such as service worker differences and immutable namespaces).
  • Native Performance:Runs converted extensions directly inside Safari's engine rather than running a background Chromium instance, preserving battery life and system memory.
  • Chrome Web Store Integration: Injects an "Add to Safari" button directly into the Chrome Web Store interface.
