The short version

  • Only Doppler has a free tier, so it costs nothing to try first.
  • Each has a real cost: Doppler developer tier limited to 3 free users with per-user fees beyond that; Trimble Unity Maintain esri ArcGIS is a hard prerequisite, so an organisation without it faces a second substantial licence and a GIS programme before the maintenance system can be used at all.
  • They diverge on capability: Doppler covers Secrets management, Trimble Unity Maintain covers Built on ArcGIS.
  • 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.

Doppler

  • Developer tier limited to 3 free users with per-user fees beyond that
  • Team plan pricing ($21/user/mo) adds cost for large teams
  • 90-day activity log retention may be insufficient for long-term audits
  • Enterprise plan requires custom pricing conversation

Trimble Unity Maintain

  • Esri ArcGIS is a hard prerequisite, so an organisation without it faces a second substantial licence and a GIS programme before the maintenance system can be used at all.
  • The product is mid-rename from Cityworks to Trimble Unity Maintain with transition timelines Trimble has not committed to publicly, leaving contracts, documentation and integrator experience split between two names.
  • CVE-2025-0994, a deserialisation flaw in Cityworks, was exploited in the wild and listed by CISA in February 2025, which makes on-premise deployments a patching obligation rather than a set-and-forget install.
  • Because assets live in the GIS, changing the asset model is a GIS division change, so maintenance teams cannot restructure their own hierarchy without another department in the loop.
  • It is built for North American public sector practice, and the permitting, funding source and reporting models do not map cleanly onto other countries or onto private industrial estates.
