Best Free BitTorrent Client

 
In a Hurry?
  Go straight to the Quick Selection Guide
 
Introduction

Since its inauspicious public appearance just under 12 years ago  bittorrent has become one of the major download formats. With good reason too: it's fast, equitable and efficient. For the downloader, bittorrent offers an uncorrupted copy of the original with the option to stop the download at any time and re-start from where the download left off (very useful for those on shaky internet connections)
f you haven't yet installed a Bittorrent client on your PC, you should as there are some great freeware clients available.   In Bittorrent the best clients are free.  (In fact, if a client costs money, it is most likely a scam).

This article is part of a series of articles on bittorrent here at Gizmo's Freeware.  If you are not familiar with bittorrent, then before using this article you should read this:

There are setup guides here at Gizmo's Freeware for each of these suggested free bittorrent clients.  Links to the guides are with the product description in the Quick Selection Guide at the end of the review.

This review was prepared on February 8, 2013, and the testing was conducted in the two weeks before that date and used the latest versions of the clients at that time.

Testing

Anyone with knowledge of bittorrent knows that it is nearly impossible to have a testing procedure that is foolproof in measuring small differentials in speed among bittorrent clients.  This is due to the fact that your download speed depends on the upload of other active users and there is no control over their actions while testing.  However, I have been testing clients for this category for several years and am convinced that the better clients can be separated from the others.

There were 7 rounds of testing to boil down the 17 clients tested to the 7 in the review.    Six torrents and three magnet links were used in this part of the testing.  I then conducted several tests in two rounds of testing to determine the Top Pick.  I did post pdf copies of my notes for each round of testing:  Bittorrent Testing 2013 Notes

All of the clients listed in the review had excellent performance on all of the testing, so all are superior bittorrent clients.  The speed performance on the testing was a factor.  Even though the speed differences were small, some consistently performed slightly better.  Features and support were also factors.  CPU and RAM mattered in that a client without many features that had high CPU or RAM use would fall to one with low CPU/RAM use.  Toolbars and addons in the installation process were a slight factor.

Testing was performed on Windows 7 64bit.

About Me

I am not a technical expert, but I  have been using bittorrent since 2003.  Before coming to Gizmo's I was the Administrator at a general bittorrent forum site, giving assistance on a variety of clients, and a moderator at the Vuze fora.  I still view a number of bittorrent fora and the fora of the various bittorrent clients.  This gives me a good idea of what the average user is looking for in a bittorrent client.

Ranking

All of these clients have the basic bittorrent features like DHT, PEX, encryption and UPnP. 

All seven of the bittorrent clients listed here performed excellently on all test torrents.  Speed and performance was a factor, but features and support facilities were major considerations.  A clean installation (without toolbars or ads) was a plus.

Most people just want a client to download torrents, but there are some features that a number of users like to use, such as a built in IP Filter, use of RSS feeds, proxy support, a scheduler and a web interface.

I will make note of those that have installs or other changes to your system that are not necessary for the proper function of the bittorrent client.   I strongly suggest that if you choose a bittorrent client that has these unnecessary add ons, to not accept those changes or add ons.  I have put up guides to help with the installation of the three clients that have these unnecessary steps in the installation process.

 
Discussion

 All seven of these clients performed excellently on all the test torrents and any one of them will meet your needs as a bittorrent client.  There was some slight download speed differentials, but nothing too significant.

tixati-main-screen-thumbTixati is the top pick this year as it runs fast, offers a lot of information and has the most appealing interface in a very efficient package, RAM and CPU wise. 
Tixati always seems to be in active development and the developers are receptive to users input.  The wide variety of layout options are indicative of their responsiveness to users.  Tixati has all the features that an average user wants.
Their help facilities have grown, but have gotten a bit out of date..  Their forums are responsive,
I was surprised to find that Tixati does not support web seeds.  Generally not an issue, but there will be an issue with the 3 million torrents at Archive.org as many of those are seeded by web seeds. 
Many users will like the colored display and the many options for display as well as the vast amount of information offered within a program that uses relatively little system resources.  The clean install will appeal to all.

Pros:  Stable and efficient with a good variety of options.  Developers are active and responsive to user requests.  Attractive interface.  Good help resources.  Clean install.

Cons:   Help resource, though very good, could use some updates.  No support for web seeds.

qbittorrent-main-screen-thumbqBittorrent is the choice for those users that just want to download torrents and are not interested in graphs, extra information and display.  qBittorrent tested slightly faster on the test torrents consistently.  Its RAM and CPU use make it the most efficient client here.
It has all the features that an ordinary user would want. Their built in search runs quick and has a good number of sites included at default.  I am usually not a big fan of built in searches, but this one is superior to the rest.  Plugins for additional sites are available.   
The Wiki  has improved, but is not among the best..  The situation at the forums is good.   Response at their bugs page is excellent and the responses are from the developer.  
qBittorrent has been the Top Pick here at TSA for a few years and was only a sliver behind Tixati this year.  This is an excellent client that is fast with all the features an average user needs with small CPU and RAM use and a clean install.

 Pros:  Low and stable RAM and CPU with all the necessary features.  Fastest performance on torrents.  Development still seems to be very active and responsive to users.  Clean install, no addons etc.  Cross platform client.

Cons:  Support has improved, but could be better.   Not that well known and not accepted at many private torrent sites (though the situation is improving).

These next three clients include the Spigot Toolbar along with home page and search engine changes in their installation.  The Spigot toolbar is considered malware by many and their site has a red (high risk) warning from WOT.  2 also have Open Candy software suggestions during install and 1 has software suggestions that may be Open Candy, but I cannot confirm. 

I suggest that you decline all such offers.  Since I have seen so many users complain of the toolbars and changes taking effect after installation, I have put up installation guides (see Quick Selection Guide)  to help avoid these unnecessary extras,

I had considered removing these three from the suggested list because of the Spigot toolbar.  However, since I am going to start re-testing (and re-writing this review) soon, I will leave as is for now.

I strongly suggest that you use one of the other 4 clients suggested here.

vuze-main-screen-thumbVuze  is a good choice for those users that utilize a VPN or proxy, due to its options that can stop all activity off the VPN or proxy (useful if the VPN/Proxy goes down) and its option to disable IPv6 support (for VPNs that have an IPv6 leak.
Vuze is still an excellent client with a wide variety of plugins  and options and information.   They were the first bittorrent client to add streaming capabiities.
Their help resources (Vuze-Wiki and Vuze forums) have taken a step back, but the Wiki is still an excellent source of information and the fora does provide decent support. 
Although the client has improved its RAM use greatly since the Azureus model, it still is the big RAM user here, though this is really not an issue in this day and age.
Their install includes a toolbar and home and search page changes enabled at default.  There is also a software install offered  and it also has advertisements in the Vuze portion of the client (can be avoided by  using the "Classic" interface).
Many users like the intricate details this program provides, its streaming capabilities and its VPN and Proxy support is superior to other bittorrent clients.

Pros: There is a wide variety of options and information within the program and an impressive array of plugins to satisfy any need.  Support for VPN  and Proxy use is superior.   Streaming capability.  Cross platform. 

Cons:  Toolbar install and home page change enabled at default on install.  Advertisements within free version of Vuze interface (can be avoided by using Classic interface).  Highest RAM use of the clients here. Spigot toolbar offered during install along with home page and search engine changes.  Software offers similar to Open Candy.

utorrent-main-screen-thumbµTorrent has been top pick here in the past and is still a superior bittorrent client.
With the excellent results on the test torrents, the fact that it is a stable and low resource using client and the vast amount of features packed into this tiny program, this is a top flight bittorrent program.  
The support provided by  µTorrent's FAQs, guides and forums is excellent, though it has diminished a bit from past years. 
Streaming to devices capability has been added in recent releases.
µTorrent does try to foist a toolbar, home page change, search engine change and a software download during install.     Recent versions of µTorrent have been in disfavor at many private sites, supposedly for reporting to the tracker issues.
µTorrent has become by far and away the most popular bittorrent client due to its small, efficient, feature filled package.

Pros:  Excellent speeds on torrents, efficient and stable client with a large amount of features packed into a tiny package.  Excellent help resources. Streaming capability.

Cons:  Has had critical security alerts at Secunia. (though none on this version).  Toolbar install (not necessary for program) and search/home page change enabled at default on install.  Unnecessary software offered during install.   Recent versions of µTorrent have been in disfavor at many private sites, supposedly for reporting to the tracker issues.  Spigot toolbar offered during install along with home page and search engine changes.  Software offers from Open Candy.

bittorrent-main-screen-thumbBitTorrent.  Everything I said about µTorrent, above applies to BitTorrent as the two are identical in their options and engine.  Both are owned by BitTorrent, Inc., and are developed by the same development team.  If you prefer the name BitTorrent and its purple color over the µTorrent name and its green color, then that would be the only reason to choose this client over µTorrent.

Even though the two clients are the same, BitTorrent is still banned at most private torrent sites (even though they accept µTorrent). 

Like µTorrent, BitTorrent is a small and efficient bittorrent client with a great deal of features and will appeal to many despite the "extras" in the installation.

Bittorrent:  Spigot toolbar offered during install along with home page and search engine changes.  Software offers from Open Candy.

These last two clients offer a clean installation and performed excellently on the test torrents.  Their lack of support and some features is the reason they are last on this review.

Transmission-QT (Windows) is a basic bittorrent client that runs fast and has a simple interface.  It is missing some features and does not have much support.
This is not an "official" release of the Transmission team, but has been touted in their forums for years and now has its own site at Sourceforge.
Not quite as efficient, RAM and CPU wise as some of the other offerings here that have more features.
The clean install and basic interface will appeal to those who just want to download torrents and do not need any bells and whistles.  This Windows port of Transmission will give you speed with the best.

Pros:  Efficient and stable with excellent speeds.  Simple interface.  Clean install, no addons etc.

Cons:  Not an "official" release of the Transmission team and is lacking help resources.  Missing some features

halite-screenshot-thumbHalite has the smallest RAM use of the seven clients.  It is a clean, small and fast bittorrent client, but lacks some features and has almost no support facilities.  If you just want to download torrents on a client with a simple interface, the Halite is a nice choice.
Halite was off this list in last review as it had not been updated within a year.  The version tested here was released just prior to the testing for this review.  So, there is some uncertainty for continued updates. 
This is a good client for those who want a simple, no frills bittorrent client.

Pros:  Small, efficient and fast bittorrent client.  Lowest RAM use of the suggested clients.

Cons:  Missing some features.  Support is weak.  Releases have been sporadic.

If you are using Win 7, or 8, or Vista, you might have to try right clicking and run it as administrator, and then make the changes in settings for it to stick.

by freestuffrocks on 23. January 2013 - 12:47  (104751)

Thanks a lot Anupam. They now stay checked! Never had to run as administrator before with torrent clients. I wish I'd noticed earlier those boxes weren't staying checked. Anyway qBittorrent appears to be working fine now.

by mr6n8 on 23. January 2013 - 13:04  (104755)

I just installed 3.0.8 and had the same issue. Run as administrator does make them stick. I had checked with that change in BitTorrent and did not need to run as administrator to make the change (and the icons for torrents changed). When I run qBittorrent as administrator and enable those boxes they stay ticked, but my torrent files do not show qBittorrent as the default. UPdate - it took a reboot to change the file association.

However, I ran the LibreOffice torrent in qBittorrent and it immediately went up to my max download speed.

by Anupam on 23. January 2013 - 12:57  (104754)

Glad to know :). Well, in XP, this was not required, but with newer Windows like Win Vista/7/8, for file association settings, you are required to run the program as administrator. Good to know it's working now.
So, that means my problem becomes a mystery now :D.

by freestuffrocks on 31. January 2013 - 10:35  (104994)

I started this by saying Deluge worked fine, but that was before I tried magnet links which I can't get to work at all. qBittorrent, however, works very well in every respect. Just that UI issue with the torrent and magnet link boxes which appear checked but require administrator rights to remain so.

by mr6n8 on 17. January 2013 - 15:07  (104579)

I am going to be conducting a new round of testing soon. If you know of a program that supports bittorrent that is not listed below (and does not have an orange or red WOT rating), then please post a link here.

The program must be Windows compatible and have been updated within the past year and be free.

This year I will only be testing on my Windows 7 64bit computer as my XP has become unusable. I test each client on 3 torrents and 3 magnet links several times while cross checking with other bittorrent programs.

I will be testing the following clients:

Already in Review
qBittorrent
Tixati
Deluge
BitTorrent
uTorrent
Transmission-QT
Vuze
BitComet

Not in Review
Ares Galaxy
Free Download Manager
Frostwire
Miro
MLDonkey
Shareaza
Tribler

I do not want to get too much into the comments just below since I will be testing again, but I will say that the reason for Tixati (my personal favorite at one time) not making the top listings was trouble with two of the three magnet links used in testing. I will keep an eye our for the glitches mentioned regarding the other clients.

In years past I used my bittorrent programs throughout the year and was able to analyze such glitches better. In the past two years my use has gone way down, so that I really do not view a program outside of the week or two of testing.

Input is always welcome and I will try to find information on any issues presented by users.

by Anupam on 22. January 2013 - 16:04  (104729)

Would be interested in your review this time around. I have been using Tixati from a long time now, and am loving it. I don't even recommend utorrent, or use it anymore.

I did face Tixati hanging sometimes, as I had mentioned before. Turns out, it was because of few things. First, I was using it on an old P-III PC. So, things were already slow on it. Then, I had Avast on the PC, and it seems that Avast got Tixati to hang on its startup, or other times. When I removed Avast from system, and I had not been using any AV, Tixati did not face any problem while startup, or while adding a torrent. It did use to hang occasionally, but I think that was because of the low configuration of the PC. On newer systems, it works without problems. Atleast, from what little I have seen.

Apart from this, I haven't faced any problem with Tixati, and I love using it, and its various features.

I have currently installed it on Windows 8, will let you know how it works.

Keep up the good work mr6n8 :).. and thank you for all the hard work you do, managing this category, and many others on the site :).

by Anupam on 27. January 2013 - 9:05  (104852)

Just an update. Tixati is working great on Windows 8, without any problems at all. No hangs, nothing. Working just fine :).

by mr6n8 on 27. January 2013 - 9:46  (104855)

Thanks for that.

by bash550 on 19. January 2013 - 7:14  (104635)

I should point out that there is an alpha version of qbittorrent 3.1.0 which in my opinion seems to work better than the 3.0.6 version. Which will you be testing?

by mr6n8 on 19. January 2013 - 12:57  (104638)

Since you mentioned it, I will take a look at it in testing, but the review can not suggest an Alpha version.

Thanks for the info.

Steve

by bash550 on 20. January 2013 - 13:06  (104671)

I guess, you're right. Development is currently ongoing with a new version out. Looking forward to seeing the test results.

by mr6n8 on 20. January 2013 - 14:10  (104672)

This page is viewed by a lot of new users, so it is best to keep to the stable versions. A couple times I have had to suggest an older version as the latest had quirks, but I do not like to do that either.

Anyhow, I just got an update on qBittorrent, though I do not think it is the complete update as it just went from 3.06 to 3.07. I have not checked the change log yet.

Hopefully, I'll start the testing this coming week and get the new review out shortly thereafter.

Thanks

Steve
