# qBittorrent vs Transmission vs Deluge

What Kochab exposes through each torrent client, and which one to add.

Canonical: https://kochab.io/docs/qbittorrent-vs-transmission-vs-deluge/

qBittorrent, Transmission, and Deluge are all torrent clients Kochab can add as a download
client. Transfers in the blended Downloads queue, status, pause/resume, queue drill-in, per-torrent
priority and reorder, per-torrent speed limit, seeding ratio limit, reannounce, and Search sends
work identically across all three. qBittorrent and Transmission add an alt-speed mode toggle and a
per-item seed time limit; Deluge does not expose either.

## Quick pick

| Your setup | Add this in Kochab |
|---|---|
| New torrent client, no strong preference | **qBittorrent** - the only one of the three where Kochab exposes every per-torrent control it supports |
| Already running Transmission | **Transmission** - same per-item controls as qBittorrent |
| Already running Deluge | **Deluge** - full queue control, without alt-speed mode or a seed time limit |

Kochab supports torrents, but stays Usenet-forward; SABnzbd is the primary download client
Kochab targets.

| Auth | Web UI username + password (session cookie) | Username + password (HTTP Basic, when enabled) | Web UI password only (session cookie) |

## qBittorrent

**Best for:** per-torrent control that includes a seed time limit and the alt-speed mode toggle
alongside ratio limits and reannounce.

**Exposes:** the shared set above, plus a seed time limit, the alt-speed mode toggle, and a
category list with assignment to an existing category.

**Does not expose:** labels, creating or editing categories, RSS, advanced qBittorrent settings,
or per-torrent file trees. Those stay in qBittorrent's Web UI.

## Transmission

**Best for:** stacks already running Transmission. The per-item controls match qBittorrent,
without a category-list card on the control screen.

**Exposes:** the shared set above, plus a seed time limit, the alt-speed mode toggle, and
assignment to an existing category (no category-list card).

**Does not expose:** a category list card, full Transmission settings, peer/blocklist management,
or per-torrent file priority editing; those stay in Transmission's own UI.

## Deluge

**Best for:** stacks already running Deluge, where you do not need alt-speed mode or a per-item
seed time limit.

**Exposes:** the shared set above, plus a category list and assignment when Deluge's Label plugin
is enabled. Kochab collects only a password (no username) for Deluge's session login.

**Does not expose:** a seed time limit or the alt-speed mode toggle, plugin setup, bandwidth
schedules, or full Deluge Web UI configuration - those stay in Deluge. Connect whichever one you
run: [qBittorrent](/docs/services/qbittorrent), [Transmission](/docs/services/transmission),
