Xtreme Download Manager (XDM) speeds up downloads by splitting them across multiple connections, saves videos from streaming sites, and picks up broken downloads exactly where they left off. A companion browser extension hands downloads and detected videos straight to the app, so you never have to copy a link by hand.

[!NOTE]

As of 2026 XDM is being rebuilt and is in active development.

[!WARNING]

A note for contributors: XDM is going through a major rewrite, and the code is being restructured often.

Pull requests made now may need a lot of rework, or no longer apply after the next round of changes. Please hold off

on code contributions until things settle down. Translations, bug reports and feature ideas are very welcome in the

meantime. Thank you for your patience and support!

🆕 What's new in XDM 9

XDM 9 is a ground-up rewrite. Highlights:

• Writes straight to the final file: HTTP downloads go directly into your download folder, with no temp copy

and no slow "assembling" step at the end. Large files finish the moment the last byte arrives.

• Better HLS and DASH: more reliable stream detection, a choice of quality and audio track, and muxing to MP4

without ffmpeg. You can also grab subtitles as .srt, timed to match the video.

• Bulk downloads: right-click → Download all with XDM to grab every PDF, image or video on a page. You can

also save a social media profile's videos and images in one go, with video and audio merged into ready-to-play MP4s.

• On the Chrome Web Store: install the browser extension with one click.
• Modern UI: a refreshed light and dark theme, runs natively on Wayland, a native macOS build

(Apple Silicon and Intel) and Windows on ARM64 support.

• Command-line mode: xdm-app --headless -o downloads HTTP, HLS and DASH from a terminal, with

a quality pick (-q best|720p|audio). It can run alongside the app.

• Download categories: rules sort each download into a category and folder. You can change the folder or

restart a download from the list.

• Disk errors never restart from zero: a full disk or a missing folder stops the download and keeps its

progress.

• Checksum verification: check a finished file's hash from the download-complete window or the download's

properties.

• Safer downloads: finished files are marked as coming from the internet (Mark-of-the-Web on Windows,

quarantine on macOS), so SmartScreen and Gatekeeper still check them. You can turn this off in settings.

• NTLM authentication: works with Windows/IIS servers and corporate proxies that require NTLM.

🧩 Browser integration

The extension forwards downloads and detected media to the running app over a local-only connection (127.0.0.1:8597); nothing leaves your machine.

Contributing? Commits need a DCO sign-off (see CONTRIBUTING.md). Install the hook that adds it for you, once per clone. It signs with the user.name and user.email from your git config, and works with GitHub Desktop and other tools that have no sign-off option:

# macOS / Linux
cp .githooks/prepare-commit-msg .git/hooks/ && chmod +x .git/hooks/prepare-commit-msg

:: Windows (Command Prompt)
copy .githooks\prepare-commit-msg .git\hooks\
