qBittorrent VS libtorrent

Not really. qBittorent is built on Qt (thus the prefix), and has a hand-rolled webui in pure html + css + js (with a couple of helper libraries, but no heavy frameworks):

Use this. Just google how to on ytube.

Now if curious about installing errors and other installer related issues, then here's a small collection: https://www.reddit.com/r/qBittorrent/s/cwCUg9JHLj https://github.com/qbittorrent/qBittorrent/discussions/17581 https://github.com/qbittorrent/qBittorrent/issues/17605 https://github.com/qbittorrent/qBittorrent/issues/18340 https://github.com/qbittorrent/qBittorrent/issues/19980 https://github.com/qbittorrent/qBittorrent/issues/18636 https://github.com/qbittorrent/qBittorrent/issues/19226 https://github.com/qbittorrent/qBittorrent/issues/19991 https://github.com/qbittorrent/qBittorrent/issues/19978 https://github.com/qbittorrent/qBittorrent/issues/19977

I’ve used qbittorrent for the last few years. Had no problems with it

Torrenting clients - qBittorrent still supports Win7 if you select the qt5 variant. For people that do not know what qBittorrent is - it is uTorrent, just without bloatware, ads, malware and such. It's open-source. UPDATE: it dropped Win7 support in October. ;_; (quick, somebody make a fork! https://github.com/qbittorrent/qBittorrent/ ) - here's the last downloadable Win7 version - https://www.fosshub.com/qBittorrent-old.html?dwl=qbittorrent_4.5.5_lt20_qt5_x64_setup.exe (but hey, I'm still downloading torrents fine in under WinXP 32-bit via the ancient uTorrent 2.2.1, so this version of qBittorrent might last for 10+ years for Win7...)

.........What download manager are you using there? Whatever it is, stop and uninstall it like yesterday. Get this https://www.qbittorrent.org/ and try again.

qBittorrent announces Tailscale IPs that are practically never connectable. I believe it's a bug so I reported it to qBit.

I had a longer answer, but qBittorrent is great and has a great webui/server model if you're running a separate linux box to run it in. If you're on windows, grab 4.3.9 or 4.6.2 with libtorrent 1.x. RSS stuff is nice too. Libtorrent 2.x has issues on Windows currently (read these threads if you want to know more - https://github.com/arvidn/libtorrent/pull/7013 - https://github.com/arvidn/libtorrent/issues/6667#issuecomment-1804035311 ). Please don't bug Arvid about it though. Libtorrent 2.x gets us Bittorrent v2, which is a good thing.

Where users could finally download files that were present in other swarms. This would decentralize network more, swarms with valuable files wouldn't die fast, even when updating a torrent, where info hash differs, say tv series, adding new episode, all the previous seeds of swarm could contribute bandwidth and resistance to new swarms, there were nice proposals at libtorrent project (library which many clients we know use), as f.e. not announcing that a peer has files to not overwhelm network, but announcing that he wants them.

How much of it do you want to do yourself vs how much do you want to use pre-made libraries for? Many popular clients rely on libtorrent which is a C++ torrent library: https://github.com/arvidn/libtorrent

FWIW, it seems like there'll be an update to libtorrent very soon that'll address the memory issue.

Here is a link to an issue I found on the libtorrent repo discussing the issue.

Many!
