Why free classroom tools?
Quizlet, Kahoot, Blooket and similar tools increasingly gate Learn modes, live games or student data behind school or teacher subscriptions.
Open-source options such as Anki, Moodle, H5P and ClassQuiz keep working after a trial ends, and schools can host them on their own infrastructure when privacy matters.
Every listing states whether it is fully free, open source, freemium or paid, and links to the official site so you can check current school pricing yourself.
How tools are chosen
Each listing links to the official website, states its licence and whether it is fully open source, free but proprietary, or free with paid tiers, and shows stars, last-commit date and licence from the project's public repository where it has one. Top Pick listings are clearly labelled and never change the facts shown about a tool.
