onjava.com was originally a vertical tech community for Java developers. The domain is now owned by O'Reilly, and it redirects to O'Reilly Radar, O'Reilly's tech blog and online learning platform. O'Reilly is a world-famous publisher of IT tech content, and this site aggregates its tech news, online courses, live events and other resources, covering almost all mainstream IT tech fields.
The site delivers two core values: First, it offers free tech trend content, including forward-looking column articles, podcasts and videos across fields like AI, cloud computing, development, and security. Second, it directs users to O'Reilly's paid online learning platform, which provides systematic courses, skill certifications, interactive learning, enterprise learning analytics and other features. Pricing is subscription-based, with separate plans for individuals, enterprises, governments, and higher education institutions. New users can get up to 14 days of free trial, and can also try a single course for free.
Pros: Backed by the O'Reilly brand, content quality and professionalism are guaranteed. The content keeps up with the latest tech developments, covers the full tech stack from beginner to advanced levels, and comes in a wide range of formats to fit different learning scenarios.
Cons: The original domain's Java-focused positioning is completely gone. There is no Chinese localization, subscription pricing is not publicly listed, and the overall experience is unfriendly for users based in China.
This site is suitable for developers and tech teams who want to access cutting-edge English-language tech content and improve their professional IT skills. Currently, a proxy is required to access the site normally from China. It does not support a Chinese interface, and does not accept domestic Chinese payment methods.
