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.
