The short version

  • Only Socket has a free tier, so it costs nothing to try first.
  • Each has a real cost: Socket team plan requires minimum 5-developer commitment, expensive for small teams; 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: Socket covers Malware detection, 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.

Socket

  • Team plan requires minimum 5-developer commitment, expensive for small teams
  • Business plan $50/dev/month becomes costly for teams exceeding 20 members
  • Enterprise pricing requires custom consultation with no transparent pricing
  • Free plan limited to individual developers without team collaboration
  • Reachability analysis improvement (90% false positive reduction) only on Enterprise

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.
