# 🧘‍♀️ Zen-Sync 

A Windows only command-line tool for syncing [Zen Browser](https://zen-browser.app/) data with S3-compatible storage services.

## 🤔 What it does

Since Zen Browser doesn't have proper profile sync yet, this is my quick solution built in a few hours to keep my stuffs in sync across multiple machines.

It backs up all the important stuff to any S3-compatible cloud storage so you can restore or "sync" your profile anywhere. No more manually dragging around profile folders every time you edit a settings 🥹🥹😭. I'm so done with that.

The default (customizable) setting skips session cookies, temporary storage, and other data because sites I visit can detect copied sessions through fingerprinting and will invalidate them.

## ✨ Features

- 🔄 **Bidirectional sync** between local and S3 storage
- 🔍 **Filtering**  - only syncs important files, excludes cache and temporary data
- ⚡ **"Incremental" sync** - only uploads/downloads changed files
- 🔗 **Custom S3 endpoints** - works with any S3-compatible service
