Technology is the widest part of this catalogue, and the place most people start. Underneath it sit cloud computing, artificial intelligence, cybersecurity, data science, web development, DevOps, databases, game development, UX/UI design, product management and more, each with its own page and its own filters.
Most of what is listed here is pitched at beginners, and a large share costs nothing to begin. Courses come from YouTube creators working in the open alongside structured programmes from Noble Desktop and the UC San Diego Division of Extended Studies, so a first hour of curiosity and a paid certificate track sit side by side rather than in separate worlds.
Every course is compared on the same terms: level, length, price, whether it ends in a certificate, and who stands behind it. Use the filters to narrow by subject, by level or by length, and open any course to see where it is taught before you commit an afternoon to it.
