Shrike

Selective file backup to Google Drive
macOS desktop app powered by Tauri v2 + Next.js + rsync

Shrike is a lightweight macOS app that lets you pick specific files and folders to back up to Google Drive. No full-disk sync, no bloated cloud clients -- just rsync the things you care about.

How it works:

1. Drag files onto the window (or click + to browse)
2. Hit Sync to back them up via rsync
3. Google Drive for Desktop syncs the rest to the cloud

• Drag & drop -- drop files and folders directly onto the window
• Native file picker -- click + to browse via macOS dialog
• Quick Add wizard -- scan and batch-add coding agent configs (.claude, .cursor, .aider, etc.)
• Incremental sync -- rsync only transfers what changed
• Full path preservation -- rsync -avR keeps your directory structure intact
• Dark mode -- auto-detect system preference, or manually choose light/dark
• i18n -- English and Chinese UI, auto-detect or manually set
• Webhook trigger -- automate backups via POST http://localhost:7015/sync
• Dock & menu bar control -- hide from Dock and/or menu bar as needed
• Launch at login -- optional autostart on macOS login
• Per-device subfolder -- separate backup directories via machine name setting

Download the latest .dmg from the Releases page, open it, and drag Shrike to Applications.

• macOS (with built-in rsync / openrsync)
• Google Drive for Desktop installed and signed in

# Clone
git clone https://github.com/nocoo/shrike.git
cd shrike

# Install dependencies (requires Bun + Rust)
bun install

# Run in dev mode
bun run tauri dev

# Build for release
bun run tauri build

Trigger syncs programmatically from scripts, cron jobs, or automation tools:

# Trigger a sync
curl -X POST http://localhost:7015/sync \
  -H "Authorization: Bearer <your-token>"

# Check status
curl http://localhost:7015/status \
  -H "Authorization: Bearer <your-token>"

The token is auto-generated on first launch. Find it in Settings (gear icon).
