About this app

BrowSync is a cross-browser routing and sync hub for macOS. It unites Safari, all Chromium-based browsers, and Firefox, intelligently routing links and syncing bookmarks and sessions in real-time. Features URL Routing: Register BrowSync as the default macOS browser to direct links to specific browsers based on domain, URL patterns, query strings, source application, or time of day. Bookmark Sync: Sync bookmarks in real-time across Safari, all Chromium-based browsers, and Firefox. State Sync: Sync Cookies, LocalStorage, and sessionStorage across supported browsers to maintain login states. Tab Sharing: View active tabs across browsers. It filters out incognito tabs and non-HTTP(S) local pages, and deduplicates URLs. Sync Strategies: Supports unidirectional (master-slave), last-write-wins (based on access time), and bidirectional merging. Site Control: Manage sync scope with whitelist/blacklist rules and per-site policies. Local Network: Communication is handled locally via a WebSocket daemon (ws://127.0.0.1:62333). No external servers are used. Native macOS App: Built with SwiftUI. Supports Dark/Light themes, Menu Bar integration, and Launch at Login. iCloud Sync: Automatically sync your routing rules, settings, and site preferences across all your Mac devices via iCloud.

Baseline captured. Growth appears after the crawler observes a changed rating count.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
