A native desktop shipping tool for the solo shipper who buys and prints 50+ labels a day and wants a purpose-built UI instead of Shippo's web dashboard. Tauri 2 + Rust client with a React 19 frontend. Paste an address → regex parse → verify via Shippo → rate-shop → buy → silent print to the default 4×6 thermal printer. Customs forms appear automatically for international destinations. API credentials live in the OS keychain, never in plaintext, and every billable label purchase is gated behind explicit user confirmation.
