A blazing-fast, ultra-lightweight, and 100% native download manager engineered exclusively for macOS. Experience multi-threaded segmented acceleration, dynamic token-bucket speed throttling, flexible queue scheduling, and seamless media extraction.
Everything you expect from an elite download accelerator, packaged with the simplicity and elegance of native macOS architecture.
SwiftDL splits target files into 1, 2, 4, or 8 parallel chunks utilizing HTTP Range headers. Each segment streams concurrently over independent connections and writes directly into pre-allocated file blocks, maximizing bandwidth utilization.
Keep your Zoom meetings, 4K video streams, and online gaming silky smooth. A precision sliding-window token bucket algorithm throttles download bandwidth on-the-fly with quick presets (500 KB/s, 1 MB/s, 2 MB/s, 5 MB/s) or your custom rate.
Schedule heavy downloads to execute during off-peak hours (e.g., 1:00 AM – 6:00 AM). Select specific active days of the week, automate queue start/stop sequences, and receive local macOS notifications upon batch completion.
Integrated support for online media via automatic detection of yt-dlp across Homebrew, Python framework paths, and standard binaries. Download video streams directly through the same unified queue.
Copy any download link in Safari or Chrome, and SwiftDL auto-detects valid URLs upon focus. Paste instantly into the top quick-bar or tap the add button to configure thread count and target folder.
Incoming downloads are automatically classified into intuitive categories: Applications (dmg, pkg), Archives (zip, rar, 7z, iso), Movies (mp4, mkv), Music, and Documents.
Never lose download progress to spotty Wi-Fi or accidental drops. SwiftDL persists segment byte offsets to disk, enabling instant resume for servers supporting HTTP byte ranges without redownloading from scratch.
Strictly compliant with Apple App Store Review Guidelines and macOS App Sandbox security. All file operations remain confined to user-selected directories with zero background privilege escalation or kernel extensions.
A modern system architecture built without third-party bloat, memory leaks, or legacy baggage.
