Syzygy transforms your clipboard into a local-first workspace. Unlike cloud tools that upload unencrypted data, Syzygy keeps all history locally on disk with instant offline search, OCR, and previews for 14 document families (code, SVG, PDF, etc.). When syncing across macOS, Windows, iOS, and Android, devices connect directly via end-to-end encrypted P2P over QUIC—with zero central server storage. Large transfers stay non-blocking in the background, keeping your Command Palette instant.

Hey Product Hunt community! 👋 I’m thrilled to introduce Syzygy, a local-first clipboard workspace with zero-cloud, peer-to-peer (P2P) device sync.
Why we built Syzygy
As developers and designers, our clipboards handle the most sensitive and fragmented pieces of our daily work—API tokens, SSH commands, Figma vector graphics, and meeting screenshots. Yet, traditional clipboards still treat this data as an ephemeral, single-slot text buffer.
Worse, modern cloud-sync tools force two unacceptable trade-offs:
1. Privacy leaks: Your unencrypted clipboard payloads are uploaded to third-party cloud databases.
2. UI freezing: Large image or project sync tasks block the main thread, causing keystrokes to drop.
3. Format degradation: Copying an SVG from Figma flattens it into a lossy raster image, throwing away your editable source.
We built Syzygy to challenge this. We believe your clipboard should be a calm, durable, private workspace—not an unencrypted cloud
pipeline.
What makes Syzygy different?
- 🏠 Local-First & Offline-Ready: Every snippet is stored on your local disk. Full-text search, OCR, tags, and text transforms
execute in sub-milliseconds, even completely offline.
- 📐 Typed Content (multi-Document Families): We don’t just store flat strings. An SVG retains both its rendered canvas preview and editable XML source; scanned PDFs preserve their layout while exposing extracted OCR text.
- 🔒 Zero-Server P2P Synchronization: Paired devices establish direct, end-to-end encrypted QUIC tunnels across Local Networks (LAN), Tailscale/WireGuard VPNs, or encrypted relays. Our servers only validate licensing—they never store, route, or inspect your clipboard
payloads.
- ⚡ Non-Blocking Background I/O: Lightweight metadata headers sync in milliseconds. Heavy assets transfer in the background under strict byte budgets, ensuring your Command Palette (`Command + K`) never drops a frame.
Platforms & Pricing
Syzygy is available across macOS, Windows, Android, and iOS (with Linux builds available).
- Free Tier: Complete local workspace on your machine forever.
- Pro Tier: Unlocks cross-device P2P sync and encrypted relay support via transparent device seats (1 activation code = 1 seat).
