Coming from IDM?

Here's what stays the same, what's better, and what IDM still does that Zephyrus doesn't.

Why IDM users switch

  • It's free, for good. No trial that runs out, no licence key, no ads. The GNU GPL guarantees it stays free.
  • Nothing to relearn. The toolbar, categories, download list, progress window, queues, Scheduler and Options sit where you expect them. Even the command-line switches are the same: /d /p /f /a /n /s.
  • Faster where it counts. In our benchmark against IDM 6.42 on the same computer and server, Zephyrus downloaded 1 GiB in 1.0 s against 5.5 s, and a small file in 0.03 s against 3.1 s. See every run.
  • Torrents and magnet links. In the same list, with a file tree to pick from. IDM's website doesn't mention BitTorrent.
  • 86 languages built in. Right to left included, chosen on the first start.
  • Open source. Anyone can read the code, check what it does and build it. No adware, no telemetry.
  • Linux and Mac too. Builds with every release, if you use more than Windows. From version 0.5.0, Linux is no longer experimental: it is checked on GNOME, KDE Plasma, Xfce and Cinnamon.

Ahead on that line. Timings are medians of alternating runs on one computer and server; the bars are to scale.

IDM facts from internetdownloadmanager.com, checked October 2026; timings from our published benchmark with raw data. Spot a mistake? Tell us.

Switch in five minutes

  1. In IDM, choose Tasks → Export → To IDM export file and save your list.
  2. Download LOD Zephyrus Download Manager and install it; keep Set up browser integration ticked.
  3. In Zephyrus, choose Tasks → Import → From IDM export file and pick the file. Your downloads arrive with their addresses, referrers and cookies.
  4. Add the Zephyrus extension to your browser (how) and turn IDM's off, so only one of them takes your downloads.

What IDM still does that Zephyrus doesn't

We'd rather you knew. IDM has a site grabber that follows a whole website's pages (Zephyrus's link grabber takes the links of one page), and many years of polish and compatibility fixes. Zephyrus is new; if something you rely on is missing, ask for it.

Questions

What is the best free alternative to IDM?

If you want Internet Download Manager's layout without its price, LOD Zephyrus Download Manager: free and open source, laid out like IDM, and it imports your IDM list. If you need something else first, such as an Android app or a particular feature, the comparison above shows what each of the others is good at.

Is there an open-source IDM?

IDM itself is closed source. LOD Zephyrus Download Manager is open source (GPL-3.0) and laid out the way IDM users expect, but it's a separate program written from scratch. Anyone can read its code on GitHub.

Is it related to IDM?

No. LOD Zephyrus Download Manager is an independent project written from scratch in Rust. It has no connection to Tonec Inc. and contains none of IDM's code, artwork or text. Internet Download Manager and IDM are trademarks of their owner, named here only to compare. More

Is it really free, or a trial?

Really free, with no time limit, paid edition, ads or sign-up. More

Can I keep IDM installed too?

Yes. They don't share settings or files. Turn off one browser extension so each download goes to one program.

Does it work on Mac and Linux?

Yes: every release has builds for Linux and macOS. Today's are marked experimental; from version 0.5.0, Linux isn't, after checks on four desktops, and macOS stays experimental. Windows 10 and 11 are the main platform. More

IDM's layout. Free.

Bring your IDM list, keep your habits, and download faster. Free and open source, for good.
