misterdownloadmanager: 1GB in 1 second: A Rust-based download manager as an alternative to IDM

An open-source download manager written purely in Rust. Unlike traditional methods, it fetches file chunks concurrently and redistributes them dynamically, achieving a download speed of 1 second for a 1GB file. It measured 5.5 times faster performance than IDM in the same environment and consumes less CPU.

A browser extension automatically captures downloads from Firefox, Chrome, Edge, and others. It supports YouTube videos, gallery images, torrents, and magnet links, and can also download file hosting links via debrid accounts such as Real-Debrid. It can resume after crashes or disconnections, making it suitable for stable large-scale transfers.

It supports Windows, Linux, and macOS, and is available in 86 languages. It has no ads or sign-up process and is distributed under the GPL-3.0 license. It can run headlessly in Docker or Unraid environments, or control downloads by integrating with AI assistants like Claude and Cursor via an MCP server.

It serves as an alternative for developers who find IDM's paid license or 30-day free trial burdensome. A portable version that runs directly from a USB drive is also provided, and it includes network control features such as specifying a dedicated network adapter for VPNs and configuring encrypted DNS.
