MySync - Open-Source Cross-Browser Sync Tool

Overview

MySync is a lightweight, open-source browser extension designed to solve the friction of working across multiple web browsers. Whether you are developing on Linux, testing on macOS, or simply prefer using both Chrome and Firefox for different tasks, MySync ensures your browsing environment stays unified.

Unlike proprietary syncing solutions that lock you into a single browser ecosystem or track your data, MySync is built with a privacy-first approach. It securely bridges your data between Google Chrome and Mozilla Firefox, ensuring your workflow remains uninterrupted and entirely under your control.

Key Features

  • Seamless Cross-Browser Syncing: Instantly synchronize your essential browser data between Chrome and Firefox environments without manual exports or imports.

  • Privacy-First & Secure: Your data belongs to you. The extension is built to prioritize data security without unnecessary tracking or telemetry.

  • Lightweight Performance: Engineered to run quietly in the background without draining system resources or slowing down browser performance.

  • FOSS (Free and Open-Source Software): Fully open-source and transparent. Developers can inspect the code, contribute to the repository, or customize the extension for their own specific use cases.

  • Simple Setup: A frictionless installation process that gets your browsers talking to each other in seconds.
