HYDRA is a high-performance network file retriever designed for speed, resilience, and adaptability. It dynamically partitions downloads across multiple connections and independent mirror sources, continuously rebalancing work to maximize throughput without stalling on slow peers. It ships as both a wget/curl-compatible CLI and a cross-platform desktop download manager with browser integration.

Features

  • Adaptive Concurrency — splits files across connections and mirrors, rebalancing live
  • Range Stealing — reassigns work from slow peers to fast ones automatically
  • Stall Detection — statistical estimators catch degraded connections early
  • Broad Protocol Support — HTTP(S), FTP, CONNECT tunneling, SOCKS4/4a/5
  • Integrity Checks — checksum manifests plus Reed–Solomon bitrot protection
  • Flat Memory Use — direct positioned writes keep RAM usage constant
  • wget / curl Compatible — drop-in flag and dialect support
  • Interactive TUI — manage, pause, resume, and monitor queued downloads
  • Smart File Sorting — content-based type detection and auto-sort
  • Remote Checksum Lookup — verify server-advertised digests before or after download
  • Cross-Platform App — Windows, macOS, and Linux with categories and progress detail
  • Browser Integration — Chrome, Edge, Firefox, and Safari extensions hand off downloads
  • Queue & Scheduler — scheduled start/stop times with retry tracking
