AddressBrain vs getAddress.io
getAddress.io alternative with monthly allowances instead of daily caps
getAddress.io is a popular, developer-friendly UK address API on Royal Mail PAF data, with plans priced by lookups per day. AddressBrain is Royal Mail-licensed UK postcode lookup, autocomplete and validation on monthly allowances, built for checkouts where traffic spikes on the days that matter.
Free trial: 30 lookups a day for 30 days. No card required.

The honest comparison
Same data, different way to meter it
Both are built on Royal Mail PAF, both are quick to integrate, and both let you start free. getAddress.io has earned its following with a simple API and straightforward per-day plans.
A daily cap is a good fit for steady traffic. It is a less good fit for a retailer whose Black Friday is twenty times a Tuesday, or an onboarding flow that runs in bursts. AddressBrain meters by the month, so a busy day does not hit a ceiling.

Daily caps vs
monthly allowances
With a daily limit, unused lookups on quiet days are gone and the busy day is the one that runs out. A monthly allowance lets quiet days fund busy ones. Which suits you depends on how spiky your traffic is.
Validation, not just lookup
AddressBrain validates and normalises addresses you already hold, one at a time or in batch, on the same key as lookup, so marketplace orders, phone orders and imported records get the same treatment as checkout.

Plans sized to your month, not your busiest day.
