The short version

  • Each has a real cost: Deluge it has no built in search tab, so finding torrents needs a separate tool, the same gap Transmission has against qBittorrent.; TreeSize it traverses directories rather than reading the NTFS master file table, so a local drive scan takes noticeably longer than the fastest alternatives.
  • They diverge on capability: Deluge covers Daemon and thin-client split, TreeSize covers Free edition licensed for business.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Deluge

  • It has no built in search tab, so finding torrents needs a separate tool, the same gap Transmission has against qBittorrent.
  • The default GTK client interface looks and feels less polished than qBittorrent fuller desktop application.
  • Getting the most out of Deluge, particularly plugins and remote daemon setup, requires more manual configuration than either rival.
  • As with any torrent client, legal use depends entirely on the content being downloaded, which the app does not moderate.
  • Plugin quality and maintenance varies since many are community contributed rather than officially supported.

TreeSize

  • It traverses directories rather than reading the NTFS master file table, so a local drive scan takes noticeably longer than the fastest alternatives.
  • It is Windows only, so file servers running Linux or a NAS appliance need a different tool or a share mounted from a Windows machine.
  • Useful features are spread across three paid tiers, so the single capability a buyer needs frequently sits two tiers above the one they were considering.
  • Scanning large network shares generates significant traffic and takes hours, which means it has to be scheduled rather than run when someone asks the question.
  • Pricing is per licence with separate maintenance, so an accurate total for a team requires a quote rather than a figure from the website.

Answered from the vendors’ own pages

Deluge: Is Deluge free?

Yes, entirely, and it is open source with no paid tier or ads.

TreeSize: Is TreeSize Free really free for business use?

Yes. JAM Software licenses the free edition for private and commercial use, which is the main reason it appears on corporate machines where other free analysers are not permitted.

Deluge: What makes Deluge different from qBittorrent and Transmission?

Its daemon and thin-client architecture, which lets a lightweight client fully control a Deluge daemon running on a separate machine, a feature neither rival natively matches.

TreeSize: Why is it slower than WizTree?

Method. WizTree reads the NTFS master file table; TreeSize walks the directory tree, which is slower but works on network shares and non-NTFS volumes.

Deluge: Does Deluge have built in search?

No. Like Transmission, it relies on a separate search tool rather than an integrated search tab.

TreeSize: Can it scan a NAS or Linux file server?

It scans them as network shares over SMB, with the speed penalty that implies. There is no agent that runs on the server itself.

TreeSize: What does the Enterprise tier add?

Scheduled unattended scans, stored historical results and reporting across servers, which is the difference between a cleanup tool and a storage reporting system.
