## What it is
Profile-sync-daemon (psd) is a small shell-based pseudo-daemon that moves browser profile directories into tmpfs (RAM) via symlinks and periodically syncs them back to disk with rsync. It reduces HDD/SSD wear and speeds up browsers while remaining transparent to the user.

## Use cases
- speed up firefox and chrome by keeping profiles in ram
- reduce ssd wear from constant browser disk writes
- sync browser profile from tmpfs back to disk periodically
- manage browser profiles in tmpfs on linux
- keep browser profile backups with rsync

## When to choose
- you run Linux with plenty of free RAM and want faster browser startup and page loads
- you want to reduce SSD write wear from browser profile churn
- you use a supported browser like Firefox, Chromium, Chrome, or Vivaldi and want a transparent, set-and-forget solution

## When to avoid
- your home directory uses eCryptFS, where psd is known to risk browser corruption
- you have very limited RAM and cannot afford holding profiles in tmpfs
- you need a solution for Windows or macOS - psd is Linux-only
