FlagQuiz.co is built on the work of these open-source projects. Thank you to everyone who maintains them.

Flag artwork

Flag images come from flag-icons, Copyright (c) 2013 Panayiotis Lipiridis, released under the MIT License. The images are shown in a 4:3 format, so some flags differ from their official proportions. We changed the South Sudan and Honduras images to match changes those countries made in 2023 and 2026.

Country data

Country names, capitals, languages, currencies, borders and regions come from mledoze/countries, made available under the Open Database License (ODbL) 1.0. We have made small changes, such as adding common alternative names for quiz answers.
