In their own words
Edabit
Edabit is a web-based service for practicing programming through interactive coding challenges. Its library is described as containing more than 10,000 problems, with C#, C++, Java, JavaScript, PHP, Python, Ruby, and Swift among the supported languages. Learners submit code and see test results; hints use that context to guide them without simply supplying answers. The site tracks solved challenges and levels, and awards XP according to challenge difficulty. All challenges are free to complete, and the listed Free plan costs nothing. Edabit says it is not currently selling new memberships, and does not offer student-specific or school plans. It is designed primarily for desktop use because coding works best with a physical keyboard. The service is available only to people at least 13 years old. Its privacy policy says passwords are stored encrypted, browser-server traffic uses SSL or HTTPS, and personal information is not shared for marketing or advertising. Session recordings can retain page structure and interactions for up to 30 days.
