A lightweight, self-hosted PT cross-seeding tool.

Graft (嫁接) helps you automatically cross-seed torrents across multiple PT sites by matching content fingerprints locally, without relying on cloud services.

• 🔒 Privacy First: All data stays local, no cloud dependencies
• 🚀 Single Binary: One executable, no runtime dependencies
• 🎯 Smart Matching: Content fingerprinting for accurate cross-site matching
• 🌐 Multi-Client: Supports qBittorrent and Transmission
• 🎨 Modern UI: Clean, responsive web interface
• ⚡ Fast: Built with Rust for high performance

1. Index Building: Import torrents from your download clients
2. Site Identification: Automatically identify sites from tracker URLs
3. Content Fingerprinting: Calculate fingerprints based on file structure (size, count, largest file)
4. Cross-Site Matching: Find matching content across different sites locally
5. Reseed: Download and add torrents to your client with correct save paths
