The short version

  • Each has a real cost: Kaleris the portfolio was assembled by acquisition, so the single platform description is commercial rather than technical, and connecting two Kaleris products often requires professional services and a custom interface.; Nautilus Labs limited to maritime shipping industry use case, not applicable for other transportation sectors
  • They diverge on capability: Kaleris covers Terminal operating system, Nautilus Labs covers AI-powered optimization.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Kaleris

  • The portfolio was assembled by acquisition, so the single platform description is commercial rather than technical, and connecting two Kaleris products often requires professional services and a custom interface.
  • A terminal operating system implementation runs 12 to 24 months with parallel operation, and the software licence is a minor line next to integration, equipment interfaces and retraining crane and gate staff.
  • Private equity ownership means the roadmap is shaped by acquisition strategy and an eventual exit, and a terminal signing a decade-long dependency has no visibility of who the next owner will be.
  • Configuration expertise is concentrated in the vendor and a small consultancy pool, so terminals end up buying vendor services for changes an internal team should be able to make.
  • The strength is container handling, and bulk, breakbulk and ro-ro terminals get a thinner functional fit that has to be closed with configuration and workarounds.

Nautilus Labs

  • Limited to maritime shipping industry use case, not applicable for other transportation sectors
  • Requires integration with vessel data collection systems for full functionality

Answered from the vendors’ own pages

Kaleris: Is Kaleris the same thing as Navis?

No. Navis is the terminal operating system product line, now owned by Kaleris after Cargotec sold it to Accel-KKR in 2021. Kaleris is the parent group and sells several other product lines alongside it.

Nautilus Labs: What does Nautilus Labs do?

Nautilus Labs is a maritime AI platform that optimizes vessel performance and reduces emissions through voyage optimization, real-time prediction, and post-voyage analysis. The platform helps shipping operators improve fuel efficiency and meet decarbonization goals.

Source
Kaleris: Who owns Kaleris?

It is backed by the private equity firm Accel-KKR and assembled from acquired software businesses.

Nautilus Labs: Does Nautilus Labs help with sustainability?

Yes, Nautilus Labs' primary purpose is decarbonization. The platform optimizes ETA, fuel consumption, and CII metrics while providing emission reduction recommendations and vessel maintenance insights to shipping operators.

Source
Kaleris: How long does a terminal operating system deployment take?

Plan for 12 to 24 months at a working container terminal, including parallel running. Anything shorter usually means a limited scope or a small facility.

Nautilus Labs: Who acquired Nautilus Labs?

Danelec, a Copenhagen-based maritime technology company, acquired Nautilus Labs in November 2023. The platform continues to operate and support customers on existing terms.

Source
Kaleris: Does it suit bulk or breakbulk terminals?

Less well. The functional depth is in container handling, and other cargo types require significant configuration.
