Both uTorrent and Vuze are clients of BitTorrent, owned and built by BitTorrent, Inc. Both are capable of creating, downloading and seeding the .torrent files. They can also do many smart and advanced things like downloading from RSS feeds automatically.
They use multiple trackers, ban specific IP addresses, or set download priorities separately for each file.
If any of the two are used for torrenting, their result wouldn’t have a lot of difference.
Vuze (previously known as Azureus) is written in Java and uses the Azureus Engine. The content shown to the public is in the form of various categories like tv shows, movies, etc.
All versions of uTorrent, on the other hand, are written in C++.
Key Takeaways
- uTorrent is a lightweight, easy-to-use BitTorrent client with a simple interface, while Vuze is a more advanced BitTorrent client with a built-in search engine and a media player.
- uTorrent consumes fewer system resources, making it ideal for low-end devices, while Vuze requires more resources, making it suitable for high-end devices.
- uTorrent provides fewer features but is faster, while Vuze offers more features, including HD playback and remote control, but is slower.
uTorrent vs Vuze
The difference between uTorrent and Vuze is how Vuze uses more memory than uTorrent. Vuze uses 50% more memory than uTorrent; because of this, Vuze can run almost equal to around 3000 torrents at a time.

Comparison Table
Parameters of Comparison | uTorrent | Vuze |
---|---|---|
Memory used | Very lightweight and approximately weighs 1MB | This uses 50% more memory than uTorrent does. |
Language | C++ | Java |
Portability | It does not need to be downloaded or installed to be used. It can even be directly used from an external device like a USB. | Unlike uTorrent, it can’t be used without being downloaded or installed. |
Advertisements | It shows inappropriate ads, but this can be disabled. | The ads can’t be disabled here. A certain amount of payment must be made to remove the ad. |
Strength | As it has low memory, it can run fast, but few downloads can be done simultaneously. | It is fast and has a lot more memory, so the work it does is equal to about work done by 3000 torrents. |
What is uTorrent?
It is a Bit Torrent client owned and developed by Bit Torrent Inc. Outside China, uTorrent is a widely used Bit Torrent client with about 150 million users. Its initial release was on 18 September 2005.
Since the release of this program, its development has been very active, i.e., from 2005. All versions of uTorrent have been written in C++.
uTorrent is available for many operating systems like macOS and Android. The uTorrent server is available for Linux as well.
uTorrent can be used to download an enormous amount of data, and the downloads can be paused and resumed at any time.
The biggest advantage of uTorrent is that you can transfer the data downloaded on uTorrent from one system to another, even without a complete download. Transferring it first and downloading it from the other system is possible.
If the computer/laptop is switched off while downloading, it won’t affect the download and will resume downloading after the system is switched back on.
uTorrent is a lightweight and very efficient torrent downloader. There’s no plugin support, and compared to Vuze, it has fewer features. The latest feature, though, can disable the ads through the options.
Although it’s said that Vuze is faster than uTorrent practically, it’s seen that uTorrent is faster than Vuze. uTorrent is really small with low memory, is lightweight, and uses very little CPU and RAM.

What is Vuze?
Vuze was previously known and famous as Azureus. It is also a BitTorrent client and is used to transfer all its files through the BitTorrent protocol.
The language Vuze is based on is Java, which uses Azureus Engine. Azureus not only allows downloading data liked to .torrent files but also lets the users publish and share the original HD video quality content.
Its content is shown in categories like tv shows, movies, games, music, etc. Azureus was initially released in June 2003. Later it also became one of the most popular BitTorrent clients.
The plugin that Vuze uses allows it to connect to the I2P network. This is why the torrents published earlier only on I2P are available all over the internet. It is a very powerful source for Windows, Android and Linux distributions.
Although it is not lightweight like your torrent, it can run as many as 3000 torrents simultaneously as it has a lot of memory. For several years it has been famous for the high-quality video content that it provides to its users.
It requires a Java runtime environment which is good for Vuze, letting it run on any operating system.
Main Differences Between uTorrent And Vuze
- uTorrent is lightweight and weighs almost 1MB, whereas Vuze uses 50% more memory than uTorrent.
- uTorrent works only using C++, while Vuze depends on Java which also plays a major role in letting Vuze use any operating system.
- One big advantage the uTorrent gives us is that it doesn’t need to be downloaded or installed to be used by a user, it can also be used externally using a USB, so it becomes a portable asset. In contrast, Vuze can’t be used without being downloaded or installed.
- One special feature that Vuze has is tracker exchange functionality which allows people to exchange information about the specific trackers of a given file. uTorrent does not have this function in use.
- In Vuze, if a particular file is to be upgraded, it takes as much time and space as it takes to download that file, which is very time-consuming. uTorrent doesn’t have this as an issue
- Vuze, as it takes up a lot of memory, can run thousands of torrents at a time with no problem (approx. 3000)
