Boo Downloader vs 4K Video Downloader
4K Video Downloader is the best-known desktop downloader and a genuinely polished one. Boo covers a much wider set of sites and leans harder on batch work — here is the actual difference.
The short answer
Choose Boo if you download from a wide spread of sites, work in batches, and want the extraction engine to update itself. Choose 4K Video Downloader if you mainly use the big platforms, want a Mac or Linux build today, or prefer their cheaper entry licence.
4K Video Downloader has been the default recommendation in this category for years, and deservedly — it is a clean, stable desktop app with a smart-mode workflow that a lot of people like. Boo Downloader is a newer Windows app built on a different extraction engine, which is where most of the practical differences come from.
What 4K Video Downloader is
4K Video Downloader runs as a desktop application on Windows, macOS and Linux, with a free tier that limits daily downloads and paid licences that lift those limits. It focuses on the major platforms and does that job well, with a particularly good subtitle and smart-mode implementation.

Genuinely. If any of these matter to you, use theirs.
- Mac and Linux users — Boo is Windows-only today
- A cheaper entry price if you only need the basics
- Subtitle downloading and export, which they do better than we do
- A long track record and a very large existing user base

Questions people actually ask
Is Boo Downloader a good 4K Video Downloader alternative?
On Windows, yes — particularly if you download from sites beyond the big platforms, or work in large mixed batches. If you are on Mac or Linux, 4K Video Downloader is the practical choice today because we do not ship a build for those yet.
Does Boo support more sites?
Yes. Boo's engine covers more than 1300 sites. 4K Video Downloader concentrates on the major platforms and does them well.
Which is cheaper?
Usually theirs, at the entry level. We compete on site coverage, batch handling and how quickly breakages get fixed — not on being the cheapest option.
Can I use both?
Of course. They are just applications; nothing stops you keeping one for subtitles and the other for volume.
Decide with the app open
The free plan costs nothing and needs no account. Ten downloads a day at 1080p, across all 1300+ sites.
