There is no current, checkable documentation for Vuze's proxy settings. The project's wiki at wiki.vuze.com returns 404, and the last release on SourceForge is 5.7.6.0, files dated 2017-11-02. The website is up and shows no version number. So this page does not publish a Vuze menu path as verified. What it gives instead is what can still be established, a way to measure the copy you have, and where the same code is maintained today.

What can be established

  • Lineage: Vuze is the Azureus code base. BiglyBT is its maintained fork, "being maintained by two of the original developers" according to its README, and it still reads azureus.* configuration properties.
  • Licence: the Azureus lineage is GPL. The licence of the current vuze.com builds, we could not confirm.
  • Ads: the site's Vuze Plus comparison lists "No Ads" as a paid feature, which implies the free build shows ads. Whether the installer bundles offers, we could not confirm.
  • Proxy behaviour: unverifiable from Vuze's own sources. BiglyBT's wiki describes the shared Azureus-era "Connection > Proxy Options" for BiglyBT; it is a fair guess that an old Vuze build resembles it, and only a guess.

What applies to any client on our proxies

Treat our SOCKS5 as TCP only. We do not advertise UDP relay, so DHT, UDP trackers and uTP will not work through it. An HTTP proxy carries no UDP in any client. A proxy does not encrypt traffic, and every connection a client makes outside it shows your own IP. Residential traffic, and traffic past a shared IP's included gigabyte, is billed per GB, so a seeded torrent pays for its payload going out as well as coming in; the terms define the count. Unauthorised sharing through our proxies is not allowed under the allowed-use policy. And if the worry is copyright enforcement, client projects' own documentation, the qBittorrent wiki for one, points to a VPN.

Measure your copy instead of trusting it

An unmaintained client plus an undocumented setting is exactly the case for a socket count. With your proxy configured in Vuze and a lawful torrent running, find the client's process ID (ps -e on Linux, the Details tab of Task Manager on Windows) and list its sockets by that ID:

ss -Htnp state established | grep "pid=1234,"
ss -Huanp | grep "pid=1234,"

On Windows:

Get-NetTCPConnection -OwningProcess 1234 -State Established | Group-Object RemoteAddress | Select-Object Count, Name

Every TCP connection should point at your proxy's address. Then capture the client's UDP port for a minute; packets to public addresses on that port are DHT or uTP leaving direct. Compare the exit address with the one the curl line on our proxy checker prints. If anything goes direct and the setting that controls it cannot be found, that is your answer about this client.

The cost of staying on Vuze

On the meter, a dormant client costs what any other does: a 6 GB image downloaded and seeded to a ratio of 1.0 is 12 GB through proxied peers, $47.40 on residential at checkout, or a datacenter IP at $1.90/IP (dedicated) a month with no bandwidth cap. Peer-to-peer traffic for lawful content is fine on residential and on dedicated ISP and datacenter IPs, which carry no traffic meter. The bigger cost is the one you cannot measure ahead of time: no release since 2017, for a program that talks to strangers on the internet all day.

Move to BiglyBT

BiglyBT is current (4.1.0.0, May 2026), has no third-party installer offers according to its site, and its proxy behaviour is the best documented of any client we cover, down to a built-in Test SOCKS button. Our BiglyBT proxy guide takes it through the same measurement, and the torrent client comparison shows Vuze among the clients we could not verify.
