Well if you want it, it will always be available right here:

The passport compatibility information is automatically refreshed on a daily basis.

There are some UI quirks which take a minute or two to figure out and I'm not going to change it. The search box is somewhat unconventional because making a list of tens of thousands of cities is not performant or easily navigable so you have to search and then filter the results.

Where do you get the data from? This incredibly useful!

City names are from Natural Earth: https://www.naturalearthdata.com/downloads/10m-cultural-vect...

Passport data largely from https://www.passportindex.org with fallback to Wikipedia scraper

Monetary per diem estimates come from a multitude of sources and then blended together into a interpolated raster which the backend uses to query so that there are no empty spots for cities with no data.

Transit connection estimates are based on GTFS and airline sources

I also expose some of this data in my other tools:

- Reverse flight search https://unli.xyz/flights/

- Gap year planner https://unli.xyz/city/calc/

I was especially interested in the passport requirements. It would be a nice addition to my website (see my comment above), instead of linking to BAMF's slightly confusing page. A simple dropdown with crude geolocation guessing would be wonderful.

Your website is a really good idea. I always refer to Wikipedia to know the entry requirements for Canadians, because embassy websites do a terrible job of sharing the most basic information.

I always wanted to build a technical travel atlas that would give basic information like power socket type, average weather, driving requirements etc. It would be a lot better than relying on a bunch of wordy travel blogs. If the APIs are there, it would be very doable.
