The short version

  • Only Davis Instruments WeatherLink has a free tier, so it costs nothing to try first.
  • Each has a real cost: DairyComp the command language interface takes weeks to learn and effectively ties the dairy to whichever staff member knows it, so losing a herd manager can strand the herd record until someone else is trained.; Davis Instruments WeatherLink pricing is per device, so a grower with a dozen stations pays a dozen subscriptions, and at Pro+ that is over 1,200 US dollars a year in software on top of hardware that already cost several thousand.
  • They diverge on capability: DairyComp covers Command language reporting, Davis Instruments WeatherLink covers Per-station cloud dashboards.
  • 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.

DairyComp

  • The command language interface takes weeks to learn and effectively ties the dairy to whichever staff member knows it, so losing a herd manager can strand the herd record until someone else is trained.
  • It is a Windows desktop application at heart rather than a cloud service, so multi-site access, remote working and mobile data entry are bolt-ons rather than native, and back-ups are the dairy's own problem.
  • Zoetis ownership puts a pharmaceutical company in control of every treatment record on the farm and biases the integration roadmap towards Zoetis sensors and services rather than the best available.
  • No pricing is published anywhere, so herd-size-based quotes vary by dealer and there is no way to benchmark what you are being charged without asking neighbouring dairies.
  • It assumes North American dairy conventions, so European dairies dealing with different milk recording bodies, national herd databases and statutory reporting formats find the fit poor and often need local software alongside.

Davis Instruments WeatherLink

  • Pricing is per device, so a grower with a dozen stations pays a dozen subscriptions, and at Pro+ that is over 1,200 US dollars a year in software on top of hardware that already cost several thousand.
  • The free tier only uploads to third parties every 15 minutes, which is too coarse for frost protection and short-interval spray decisions, so the tier that exists is not the tier a commercial grower can use.
  • Davis directs bulk device management to a sales conversation rather than publishing a volume discount, so large networks cannot budget from the public rate card.
  • Three-year commitments are the only way to reach the lower per-device rate, which locks a grower into a platform for longer than a station deployment plan often survives.
  • The hardware is durable enough to outlive several software generations, and owners of older Vantage stations have repeatedly had to buy new data loggers or gateways to stay compatible with the current cloud, turning a maintenance-free instrument into a recurring purchase.

Answered from the vendors’ own pages

DairyComp: Who owns DairyComp now?

Zoetis, through its acquisition of Valley Agricultural Software. It sits in the same portfolio as the Smartbow cow monitoring system.

Davis Instruments WeatherLink: Is WeatherLink free?

There is a permanently free Basic tier with charting and export, but third-party uploads run only every 15 minutes and there are no shareable links.

DairyComp: Is it hard to learn?

Yes, genuinely. It is driven by a typed command language rather than menus, and most new users need weeks of practice before they are productive.

Davis Instruments WeatherLink: What does the paid tier actually add?

Faster upload intervals, five minutes on Pro and one minute on Pro+, plus shareable public links. The faster cadence is what matters for frost and spray timing.

DairyComp: Does it run in the cloud?

It is fundamentally a Windows application. Hosted and multi-site arrangements exist but the software is not a browser-native cloud product.

Davis Instruments WeatherLink: Is pricing per account or per station?

Per device. Every station you own needs its own subscription.

DairyComp: What does it cost?

Nothing is published. Pricing is quoted per dairy based on herd size, plus separate charges for support and for each parlour or meter interface.

Davis Instruments WeatherLink: Can I get the data out via an API?

Yes, Davis publishes a WeatherLink API, but practical use depends on your account tier and station model, so confirm before designing around it.
