The short version

  • Only Rectangle has a free tier, so it costs nothing to try first.
  • Each has a real cost: Rectangle rectangle Pro is a separate app rather than an in-app purchase, so upgrading means installing and managing a second piece of software.; 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.
  • They diverge on capability: Rectangle covers Keyboard shortcuts, Sedaru covers Esri-native asset model.
  • 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.

Rectangle

  • Rectangle Pro is a separate app rather than an in-app purchase, so upgrading means installing and managing a second piece of software.
  • It is Mac only, so it offers nothing for a user who also runs Windows and wants one window manager everywhere.
  • It has no official paid support channel, being a community open source project, so issues are handled through GitHub rather than a vendor support desk.
  • Some very old or unusually built third party apps still resist Rectangle window snapping, a limitation shared with most third party window managers on macOS.
  • Because it is not distributed through the Mac App Store, some users have to manually approve accessibility permissions and updates rather than getting silent App Store updates.

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.
