Built from the ground up with safety, transparency, and simplicity at its
core.
Safety Layer
Preview every change before it happens. Write-ahead journal records each
operation. Undo any sync batch with a single click. Deletion guards block accidental mass data loss.
14+ Cloud Providers
Google Drive, OneDrive, Dropbox, S3, R2, SFTP, Proton Drive, and more.
Unlimited accounts per provider no per-account licensing fees, ever.
Bidirectional Sync
True two-way sync with conflict detection. Compare size, timestamp, and
hash side-by-side. Choose to keep local, remote, or both per file, every time.
Preview Every Change Before You Sync
Every change previewed before it runs. No silent overwrites, no surprise
deletions. Confirm once, then sync with confidence.
CLI & Daemon Mode
Full headless operation for servers and NAS deployments. Sync specific
pairs, sync all, run as a background daemon all scriptable.
Real-Time Watcher
Native filesystem watcher triggers sync automatically. Smart cooldown and
suppression prevent feedback loops and redundant syncs.
Dramatically more efficient
SynciZen's Rust-native architecture delivers unprecedented performance.
Full-featured sync that respects your system resources.
16× Less CPU
Windows active sync
Up to 20× less when idle. 7.8× on macOS, 2.6× on Linux. Keeps your system
cool, responsive, and battery-friendly across all platforms.
262 MB Less RAM
Linux active sync
42 MB less on macOS, 29 MB less on Windows. No Electron bloat just pure
Rust efficiency. Frees up memory for what matters.
8.7× Lower Peaks
Linux · 3.8× on macOS
3.5× on Windows. Zero CPU spikes above 20% during active sync. Your system
stays in control, always.
