I'm working on a Duolingo for programming languages and framework. Unlike Duolingo it's a real space repetition system

Interesting idea. What languages do you support? Can it be used without a subscription?

		Rust, Go, Typescript, JavaScript, Python, Ruby, React, Dart, CSS for now. Rails is almost done, Django, fast API, JVM languages coming soon after. You can try the first module of any course without login, all beginners courses are free after login, a subscription is required for advanced courses
