The short version
- Only TreeSize has a free tier, so it costs nothing to try first.
- Each has a real cost: Sedaru the Esri dependency is absolute: an ArcGIS licence is a separate and substantial cost outside the Sedaru contract, and utilities without ArcGIS must buy into that platform before Sedaru is even usable.; 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: Sedaru covers Esri-native asset model, 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.
Sedaru
- The Esri dependency is absolute: an ArcGIS licence is a separate and substantial cost outside the Sedaru contract, and utilities without ArcGIS must buy into that platform before Sedaru is even usable.
- Sedaru inherits GIS data quality, so a utility with an incomplete or stale geodatabase discovers the gaps in front of field crews rather than fixing them, and the data remediation project is not in the Sedaru quote.
- The North American water focus means limited relevance and limited implementation support outside that market, particularly for utilities operating under European or Australian regulatory reporting requirements.
- Nothing is published on price and the product is sold within a large corporate portfolio, so a small utility has little basis for judging whether the quoted subscription is competitive.
- It is a water and wastewater product; a municipality wanting one asset system across water, roads, parks and facilities will need a broader public works platform alongside 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.
- 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
Sedaru: Do I need Esri ArcGIS to use Sedaru?
Yes. Sedaru is built on the ArcGIS geodatabase and the Esri licence is a separate purchase from Esri, not part of the Sedaru subscription.
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.
Sedaru: Who owns Sedaru?
Aquatic Informatics, which is part of Veralto, the water quality group spun out of Danaher in 2023.
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.
Sedaru: Does Sedaru replace a CMMS?
For water network assets, largely yes. For plant equipment and facilities maintenance many utilities still run a separate CMMS.
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.
Sedaru: Is pricing published?
No. Subscriptions are sized on the utility and quoted, with implementation and data preparation charged as services.
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.
