Torrent clients with proxy support: all 15 ranked by how easy, and how cheap

We lined up 15 torrent clients with proxy support, or a claim to it, and asked each the same three questions. Can it send peers through a proxy? What happens to its UDP traffic? And what does that cost on a meter? The answers run from “tick two boxes” to “there is no setting”. Here is the ranking, how we got it, and the sums, so you can pick a client and a budget before a seeded ISO picks them for you.

Built from each client’s own documentation and source, read in October 2026. Every client links to its own guide, and each guide links its sources. Where something could not be confirmed, the table says so instead of guessing.

The fine print that applies to all 15

• Treat our SOCKS5 as TCP only. UDP relay is not verified on our gateways, so DHT, UDP trackers and uTP will not work through us, even in clients that could relay them. Use torrents with http:// or https:// trackers.
• Seeding pays both ways on per-GB lines. Residential, and traffic past a shared IP’s allowance, count per GB, and a client that proxies peers sends every uploaded piece through the meter. The cost section below does the sums.
• An HTTP proxy never carries UDP. Trackers and web seeds, yes; peers only through CONNECT; UDP, never.
• A proxy does not encrypt. SOCKS5 sends its password in cleartext, and BitTorrent’s protocol encryption only changes how traffic looks on the wire.
• Anything outside the proxy shows your real IP. Trackers-only modes, DHT in Tixati and aria2, Transmission’s peers, qBittorrent’s two boxes as a fresh install leaves them.
• No incoming connections. Port forwarding does nothing for proxied peers, and two proxied peers cannot reach each other.
• Not a copyright shield. qBittorrent’s wiki says that for “legal authorities and copyright trouble”, you should “consider using a VPN instead (or in addition to it)”. The proxy vs VPN guide explains the difference.
• Lawful content only. Linux and BSD ISOs, open-source releases, Internet Archive and Creative Commons media, research datasets. Using our proxies to share files you have no right to share is not allowed; the acceptable use policy is where the line lives.

The ranking

How we ranked them

This is a ranking of proxy friendliness, not of which client is nicest to use. Four questions, in this order:

1. Can it put peers behind the proxy, and is that documented? A proxy that only carries tracker requests does not change what the swarm sees.
2. Where does UDP go? Refused or disabled beats “goes direct”, which beats “nobody says”.
3. Is the setting in the interface? A checkbox you can see beats a config key you have to know about.
4. Can you control the cost? Separate tracker and peer switches, a clear peer box, anything that lets you choose how much goes through the meter.

Anything we could not confirm counted against a client. That is why Free Download Manager and Flud sit low despite their huge user numbers: maybe they do it well, but nobody documents it, and a meter you cannot predict is a meter you cannot budget for.

What each kind of client costs on the meter

Fifteen clients, three cost shapes. Which one you are in decides the bill far more than the proxy price does.

• Whole swarm through the proxy. qBittorrent with both boxes ticked, Deluge, BiglyBT, Tribler at zero hops, µTorrent and BitTorrent on SOCKS5, BitComet with no bypass, Tixati with peers proxied, rTorrent. The download comes in through the proxy, and so does every piece you seed going out. On a per-GB line, a seeded torrent pays both ways.
• Trackers only. Transmission, aria2, µTorrent on plain HTTP, qBittorrent with only the outer box, BitComet or Tixati set to trackers. Tracker requests are tiny, so the meter barely moves. Every peer still sees your real IP. Cheap, and not masking.
• Nothing. WebTorrent Desktop, and Tribler’s hop downloads, which use Tribler’s own network. Zero on our meter.

Here is the first group, priced. A 4 GB ISO, at a few seeding ratios, on residential, where you buy whole gigabytes and the order size sets the rate:

Compare a dedicated datacenter IP: $1.90 for 30 days with no traffic meter. P2P is fine on our residential IPs and on dedicated IPs with no traffic meter, as long as what you share is lawful. For any client in the first group that seeds, that flat price is usually the cheaper home, and the bandwidth calculator shows the monthly GB at which it overtakes residential. Check the thread count on the order before you let a client open hundreds of connections; more threads are a paid add-on. And keep swarms off residential anyway: those are real home connections, billed by the gigabyte. The metering explainer has the counting rules.

Reading the meter, whichever client you pick

The meter is also the best documentation some of these clients have. Three steps, five minutes:

1. Note the client’s own upload and download totals before and after one small legal test torrent.
2. Open the usage view in your dashboard for the same window and export the CSV.
3. Compare. A whole-swarm client should show roughly the torrent’s traffic. A trackers-only client should show a trickle. If the numbers say the opposite of what the settings page says, believe the numbers.

If our figure is higher than your real usage by more than overhead, the honesty page says we credit the difference, and the bill audit guide has the script to prove it. Then set an upload rate cap and a ratio at which seeding stops, before the download finishes, in whichever client you chose.

Verdict: when is a proxy worth it at all?

For one Linux ISO, it is not. Download it direct, or better, from the project’s HTTP mirror: metered nowhere, nothing to seed, done. A proxy earns its place when you want one client, and only that client, to leave from a different IP or country; when a tracker or mirror is blocked on the network you are on; or when you are testing something.

Then keep it simple. Pick from the top four, use SOCKS5, put it on a dedicated datacenter IP, cap the upload and stop at a ratio, and read the meter once to make sure the client is doing what its settings page claims. Stuck on a client that is not in the top four? Ask in the Discord; someone has probably already tested it.
