The short version

  • Only StormGlass has a free tier, so it costs nothing to try first.
  • 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.; StormGlass the free tier allows 10 API requests per day and is not licensed for commercial use
  • They diverge on capability: Kaleris covers Terminal operating system, StormGlass covers Marine weather data.
  • 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.

StormGlass

  • The free tier allows 10 API requests per day and is not licensed for commercial use
  • Commercial use and any support at all start at the Medium plan, 49 euros a month
  • The Small plan at 19 euros a month has no support and no commercial licence
  • Request allowances are daily rather than monthly, so a burst of traffic cannot borrow against a quiet week

Answered from the vendors’ own pages

StormGlass: Is there a free tier available?

Yes, Stormglass offers a free plan with 10 API requests per day, including all weather parameters, but it is not permitted for commercial use.

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

StormGlass: What does the Medium plan include?

The Medium plan costs 49 EUR per month and includes 5000 daily requests, all weather parameters, and full support for commercial use.

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.

StormGlass: Is annual billing available?

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.
