The short version

  • Each has a real cost: 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.; Tend the free tier keeps only three years of history and 500 MB of storage, so a grower who stays on it loses the multi-season comparison that makes crop planning software worth having in the first place.
  • They diverge on capability: Davis Instruments WeatherLink covers Per-station cloud dashboards, Tend covers Visual crop planning.
  • 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.

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.

Tend

  • The free tier keeps only three years of history and 500 MB of storage, so a grower who stays on it loses the multi-season comparison that makes crop planning software worth having in the first place.
  • Data retention is a paid feature at every level below Ultimate, which is an unusual thing to meter: a farm that downgrades from Pro to Free after a bad year risks losing records it may need for organic certification audits.
  • There is no machinery, telematics, soil sampling or variable-rate capability at all, so any operation that adds broadacre ground has to run a second platform rather than extend this one.
  • AI features are metered in credits rather than included, and the allowances are small at the lower tiers, so the assistant becomes something you ration rather than rely on.
  • The company is small and privately held with a narrow customer base, which means integrations outside payments and basic accounting are thin and a request for a connector to a regional distributor or certifier is unlikely to be built.

Answered from the vendors’ own pages

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.

Tend: Does Tend charge by the acre?

No. Pricing is flat by user count, and there are no acreage or crop limits on any tier including the free one. That is the main reason small growers pick it over broadacre platforms.

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.

Tend: Can Tend handle a CSA?

Yes, including member share management and a farm-stand storefront, though payment processing runs through a third party.

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

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

Tend: Is it suitable for a 500 acre grain farm?

No. There is no machinery data, no prescription writing and no as-applied reporting. It is built for high-crop-count, low-acreage operations.

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.

Tend: What happens to my records if I cancel?

Export before you cancel. Retention limits apply per tier, and the free tier keeps three years, so downgrading is not a safe archive strategy.
