Open Source Rust Download Managers

JMComic Downloader is a desktop application designed for downloading and organizing comics from the JMComic platform. It uses multithreaded downloading to retrieve comic chapters efficiently. A graphical interface allows users to search the available catalog without signing into an account. Search results lead to chapter detail pages where individual chapters can be selected for downloading. Users with platform accounts can sign in to access their favorite comic collections. The application provides direct access to downloaded files through an option to open the destination folder. Its interface is built with Tauri, combining a Rust backend with modern web technologies. Precompiled releases simplify installation, while developers can build the application from source.

Risuko is a free, open-source download manager designed to handle different types of internet downloads through a unified interface. It supports HTTP, HTTPS, FTP, BitTorrent, and magnet links for downloading files from websites and peer-to-peer networks. Its desktop application provides a clean environment for starting and managing transfers. A command-line interface allows users to perform download operations without opening the graphical application. The project includes a dedicated download engine built with Rust. Users can install the desktop or command-line editions independently according to their workflow. Distribution options include Homebrew, WinGet, APT, DNF, and npm packages. Built with Tauri and web technologies, Risuko supports modern desktop systems and includes Android build support.

FluxDown is a free, open-source download manager powered by Rust and Tokio for fast, reliable file transfers. It supports HTTP, HTTPS, FTP, BitTorrent, magnet links, eD2K, HLS, and DASH downloads. Its adaptive segmentation engine accelerates transfers by redistributing slow download segments. Users can organize tasks into scheduled queues, adjust bandwidth limits, and resume interrupted downloads. Browser extensions intercept downloads and detect supported streaming media. Automation tools include RSS subscriptions, webhooks, JavaScript plugins, and an MCP server for AI assistants. FluxDown provides desktop, mobile, web, and command-line interfaces. Optional device synchronization enables remote download management without requiring cloud accounts for local transfers.

Velox is an open-source desktop download manager for macOS and Windows. It speeds up supported downloads by splitting them into parallel connections (up to 32), with pause and resume plus recovery after an app restart. Keep a local download history, configure connection settings, and send links from Chrome, Edge, or Brave with the Velox browser extension. Browser-assisted downloads are experimental and may not work on every site. Install the Velox Browser Integration extension from the Chrome Web Store: https://chromewebstore.google.com/detail/velox-browser-integration/fghoiobfogfmjnhklgpbagdgknldfmll

Hongdown is a free, open-source Markdown formatter that automatically applies Hong Minhee's Markdown style conventions. Written in Rust, it uses the Comrak parser to process documents while preserving Markdown structure. It standardizes formatting across headings, paragraphs, lists, code blocks, and other Markdown elements. Users can format individual files, multiple documents, or entire directories recursively. A checking mode identifies files that violate formatting rules without modifying them. Its diff mode previews changes before they are applied. Configurable options include line width, code fence characters, and MDX processing. Hongdown integrates with editors and automation workflows and offers reusable Rust and WebAssembly libraries for application development.
