The dropdown that finishes the address

Type at least three characters. The counters underneath show keystrokes against calls actually made, so you can see the debounce doing its job — and how much work one completion really costs.

A coordinate, and the address at it, are facts about the world. US law recognises no copyright in facts, so keeping them needs nobody's permission — ours included. That is why storage is not a tier feature here: there is no version of this product where we could take it back.

Google's Maps Platform terms require cached geocoding results to be deleted within 30 days. Ours are yours permanently, so you never re-buy an answer you already have.

That holds on every tier, including Free, and it is the one promise on this page that rests on law rather than on our pricing — see section 5 of the terms.

The first column is the one that matters. “Right answer in the top three” is one click from done. “Right street on screen” still leaves the person hunting for the house number, and it is the number a vendor quotes when the first one is unflattering. Fully typed, ours are 77.6% and 84%.

Strongest where address entry actually happens. In major urban areas it returned a suggestion every single time we tested it, and coverage stays high across cities and suburbs. It thins out in genuinely remote areas, and the table above says by how much rather than hiding behind the national figure.

Geocodio, the closest competitor on both price and philosophy, does not offer autocomplete at all.

One session is one address being completed, however many keystrokes that takes. We bill the outcome rather than the typing, so the cost of your address box does not depend on how fast your customers type.

We are not going to pretend this one is cheap to run. It reads storage on nearly every keystroke — 1.77 reads each — which is why the free tier here is thousands of sessions rather than the hundreds of thousands of calls the geocoder gives away. Handing it over at the free tier is a pricing decision we can afford, not a property of how it is built.

A typeahead session usually ends in a geocode, and those meter separately — see geocoding. Google's Maps Platform terms require cached geocoding results to be deleted within 30 days. Ours are yours permanently, so you never re-buy an answer you already have.
