What’s a reliable free FTP client for Windows and Mac?

I’m setting up a small website and need to regularly upload and download files via FTP and SFTP. I’d like a free, secure, and easy-to-use FTP client that works well on both Windows and Mac, supports drag-and-drop, and won’t bog down my system. I’ve seen a lot of mixed reviews online and I’m not sure what’s actually safe and actively maintained. What free FTP client do you recommend and why?

If you’re just trying to push files up to a server without wrestling with terminal commands, there are a few FTP clients that keep coming up over and over. I’ve bounced between a bunch of them over the years, and these three are the ones I keep installing on new machines.


FileZilla

FileZilla is the boring but dependable option. It runs on Windows, macOS, and Linux, talks FTP, FTPS, and SFTP, and doesn’t really care if you’re throwing tiny JSON files at it or multi‑gig archives.

  • Site manager makes it easy to save a bunch of servers and flip between them.
  • The interface at https://filezilla-project.org/ looks a little old‑school, but you can figure it out in a minute or two.
  • Handles long transfers pretty well. I’ve left it running overnight with big uploads and it didn’t choke.

If you just want something that works and you don’t care about looks, this one basically does the job and gets out of your way.


Cyberduck

Cyberduck is more “app-like” and less “utility-like.” It runs on macOS and Windows and doesn’t just stop at FTP:

  • Supports FTP/S, SFTP, WebDAV, plus a bunch of cloud stuff like Dropbox and Amazon S3.
  • On macOS it feels integrated: uses system dialogs, plays nicely with Keychain, etc.
  • The interface at https://cyberduck.io/ is pretty clean, so if you hate cluttered UIs, this one’s easier on the eyes than FileZilla.

It’s a nice pick if your life is half traditional servers and half cloud storage and you don’t want five different tools for five different protocols.


Commander One (Free Version)

Commander One is for people who like the old-school dual-pane style: local on one side, remote on the other, and no mystery about what’s going where.

  • The free tier lets you connect to FTP, SFTP, and FTPS.
  • You can browse local files and server files at the same time in two panes, then just drag across.
  • It feels very “Mac-native,” so it doesn’t look or behave like a weird port.

You can grab it here:

If you’re the type who constantly compares folder trees and syncs them manually, that side‑by‑side layout saves a ton of clicks.


Which one to start with?

They’re all free to start with, so you can install a couple and see which one matches how you like to work.

If your main goal is “small website, regular SFTP, drag‑and‑drop, don’t want drama,” I’d actually start from the opposite direction of what @mikeappsreviewer suggested.

They’re right that FileZilla is the boring workhorse, but for a mixed Windows/macOS setup, I’d be a bit more picky:

  1. Cyberduck as the cross‑platform default

    • Runs on both Windows and Mac.
    • Clean UI, easy drag‑and‑drop.
    • Handles SFTP very well and has sane defaults on the security side.
    • Site bookmarks are simple to manage and syncable if you use cloud prefs.

    Where I disagree a bit with the FileZilla love: on macOS, FileZilla feels clunky and a little “un-Mac,” and the UI can be confusing for new users who just want “local on one side, server on the other, drag, done.” Cyberduck is less noisy.

  2. Commander One on Mac (paired with something else on Windows)

    If your primary machine is Mac and Windows is more of a secondary box, Commander One is a great choice:

    • Dual‑pane layout is perfect for constant uploads/downloads.
    • Native Mac feel, and SFTP support is actually solid.
    • Drag‑and‑drop between panes is super intuitive for web work.
    • Free version is enough for a basic small‑site workflow.

    The only real catch: Commander One is Mac only. So on Windows you’d still want Cyberduck or FileZilla. That combo works well in practice:

    • Mac: Commander One for day‑to‑day, Cyberduck as backup.
    • Windows: Cyberduck (or FileZilla if you tolerate the UI).
  3. When FileZilla actually makes sense

    I’d only push you to FileZilla if:

    • You care more about raw reliability and speed than UI.
    • You’re doing big overnight transfers a lot.
    • You want a single tool that behaves almost identically on both platforms.

    Just be careful on Windows to grab it from the official site and uncheck any optional bundle stuff in the installer.

If you want the simplest rule of thumb:

  • Want something that feels modern and is easy to “just use”? Cyberduck.
  • Want a very efficient Mac file manager style experience? Commander One.
  • Want old‑school, no‑frills, slightly ugly but rock solid? FileZilla.

I’d trial Cyberduck + Commander One for a week and only fall back to FileZilla if you find yourself doing heavy, constant bulk transfers where you really need that no‑nonsense queue handling.

If you want “free, secure, drag‑and‑drop, works on both Windows and Mac” and you don’t feel like babysitting the thing, here’s how I’d slice it, slightly disagreeing with both @mikeappsreviewer and @yozora.

1. Cross‑platform pick: Cyberduck (with a catch)
They’re both right that Cyberduck is the friendliest for most people. SFTP is rock solid, UI is cleaner than FileZilla, drag‑and‑drop is fine, and it doesn’t bombard you with knobs and panels.
The catch: it can feel a bit sluggish with huge directory listings, and the transfer queue UX is just “ok,” not great. For a small website, though, it’s totally fine and honestly probably the least annoying option.

2. The one nobody gives enough credit to: Commander One (Mac)
Where I disagree a bit: if you’re on Mac a lot, Commander One is not just “nice to have,” it’s arguably better than Cyberduck for day‑to‑day webdev stuff.

  • Dual‑pane layout: local on the left, server on the right, drag across, done. No mental gymnastics.
  • SFTP, FTPS, and FTP support in the free version, so your basic hosting use case is covered.
  • Feels like an actual Mac app, unlike FileZilla, which looks like it took a wrong turn out of 2007.
  • Really handy when you’re comparing folders or cleaning up old site files.

Downside: Mac only. So if you want “same client on both platforms,” this is out, but if your main work machine is a Mac, I’d honestly make Commander One your primary and something else your backup.

3. FileZilla: only if you care more about brute force than comfort
I know @mikeappsreviewer leaned on FileZilla as the dependable default, and yeah, it is dependable. But:

  • UI is cluttered and not super friendly if you just want simple uploads.
  • On macOS it feels pretty clunky.
  • On Windows, the installer occasionally tries to sneak in extras if you don’t pay attention.

Where it does win: long, heavy transfers and big queues. If you’re pushing gigabytes or syncing huge media folders, FileZilla still does that very well and almost never crashes. For a small website with mostly SFTP and regular updates, that’s prob overkill though.

4. What I’d actually do in your shoes

Given your requirements:

  • Primary cross‑platform client:
    Use Cyberduck on both Windows and Mac for the “same mental model everywhere” factor. It covers FTP and SFTP, drag‑and‑drop, site bookmarks, and decent security defaults.

  • Mac‑side upgrade:
    On Mac, install Commander One and use it as your main uploader. It turns your workflow into “file manager plus SFTP” instead of “separate FTP tool,” which is way nicer when you’re constantly tweaking your site.

  • Only pull in FileZilla if:
    You start doing massive uploads, need very robust queuing, or Cyberduck ever feels flaky for huge jobs.

That gives you:

  • Windows: Cyberduck
  • Mac: Commander One daily, Cyberduck as backup
    All free, all SFTP‑friendly, all drag‑and‑drop, without having to wrestle a dated UI unless you really want FileZilla’s muscle.
