The short version

  • Each has a real cost: 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.; Yoti age estimation returns a probabilistic range rather than a verified date of birth, so it only works with a safety buffer above the legal threshold and cannot prove an exact age.
  • They diverge on capability: Trimble Unity Maintain covers Built on ArcGIS, Yoti covers Facial age estimation.
  • 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.

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.

Yoti

  • Age estimation returns a probabilistic range rather than a verified date of birth, so it only works with a safety buffer above the legal threshold and cannot prove an exact age.
  • Estimation accuracy varies by demographic and reported error margins widen at the age bands that matter most for eighteen-year thresholds, which pushes borderline users into a document fallback you still have to pay for.
  • Pricing is not published, so buyers cannot compare the cost of an estimation check against a document check without going through sales.
  • Regulatory acceptance of facial estimation differs by jurisdiction, so a method that satisfies Ofcom may not satisfy a regulator elsewhere and multi-market platforms need more than one approach.
  • The reusable digital identity app depends on consumer adoption, which is meaningful in the UK and thin elsewhere, limiting the reusability benefit outside its home market.

Answered from the vendors’ own pages

Trimble Unity Maintain: Is Cityworks discontinued?

Not discontinued, renamed. It is becoming Trimble Unity Maintain, converging with AgileAssets, and Trimble has not published a final transition date.

Yoti: Does age estimation store my face?

The image is used to produce an estimate and then deleted rather than retained, which is the specific property that makes it usable for age assurance on minors.

Trimble Unity Maintain: Do I need Esri ArcGIS?

Yes. The product is built on ArcGIS and cannot be deployed without an Esri licence.

Yoti: Is it accepted for UK Online Safety Act compliance?

Facial age estimation is one of the methods regulators have accepted as highly effective age assurance. Confirm the current position with your own counsel for your content category.

Trimble Unity Maintain: Was there a security incident?

Yes. CVE-2025-0994 in Cityworks was exploited in the wild and added to the CISA known exploited vulnerabilities catalogue in February 2025.

Yoti: Can it prove someone is exactly 21?

No. It gives a range. If you need a precise age you need a document or database check, which Yoti also sells.

Trimble Unity Maintain: Can it handle roads and pavement as well as pipes?

Yes, through the AgileAssets lineage now inside the Unity Maintain family, which adds linear referencing for transportation assets.
