The short version

  • Only TreeSize has a free tier, so it costs nothing to try first.
  • Each has a real cost: Calsense it is a North American product with a narrow dealer network, so agencies outside the United States have effectively no route to buy or support it.; 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: Calsense covers Flow-based fault shutdown, 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.

Calsense

  • It is a North American product with a narrow dealer network, so agencies outside the United States have effectively no route to buy or support it.
  • Install cost is high relative to commercial irrigation controllers because flow sensing, master valves and proper wiring are part of the design rather than optional extras.
  • The interface and workflows are built for irrigation technicians, not casual users, so a small grounds team without a dedicated irrigation specialist will underuse most of what they paid for.
  • Public sector focus means procurement paperwork, bid specifications and cooperative contract vehicles are part of the process, which lengthens purchase timelines regardless of budget availability.
  • No pricing is published, and the no-subscription claim is conditional on the communication model chosen, so the total cost cannot be established without a specific quote and a careful read of which model applies.

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

Calsense: Is there an annual subscription?

Depending on the communication model selected, some CS3000 configurations carry no annual data or subscription fee, and some include a 4G modem with ten years of cellular data. Confirm which model your quote covers.

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.

Calsense: Does it shut off a broken pipe automatically?

Yes. It compares actual to expected flow per station and can isolate the station or shut the mainline, which is the main reason agencies specify it.

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.

Calsense: Who typically buys it?

City parks departments, school districts, universities, military bases and other large public landscapes in North America.

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.

Calsense: Does it support two-wire decoders?

Yes, along with conventional wiring and hybrid installations on the same platform.

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.
