Key Features

• 100% Standalone & Statically Linked: Pure C implementation compiled with musl libc. Zero runtime dependencies on glibc, system packages, or internet connectivity (apt-get/yum not required).
• Multi-Application Subfolder Support: Dedicated directory for each software (e.g. /Accounting/, /Warehouse/, /CRM/, or /Root/).
• Modern English Web Management Dashboard (/admin/):
  • Intuitive GUI to create and manage application folders.
  • Auto-generation of AutoUpdater.xml and AutoUpdater.json catalog files.
  • Direct file upload for update packages (.zip, .exe, .msi).
  • Automatic on-the-fly checksum computation (SHA-256 and MD5).
  • Built-in C# code snippet generator for client-side copy & paste.
  • Real-time server statistics (uptime, request count, bandwidth).
• HTTP Resume & Partial Content: Full HTTP Range: bytes=start-end support returning 206 Partial Content and Accept-Ranges: bytes for seamless, resumable downloads.
• Ultra-Fast Zero-Copy Transfer: Uses the Linux kernel sendfile(2) system call for high-throughput, low-CPU file delivery.
• Daemon & Background Ready: Included start.sh, stop.sh, status.sh, and autoupdater.service for systemd integration.
• Cross-Platform: Includes both Linux static x86_64 binary and Windows native .exe for quick local testing.
