CodeHS vs ScratchJr

CodeHS provides computer science curriculum and classroom tools for K–12 teachers, students and schools. Its catalog includes more than 100 customizable, standards-aligned courses across computer science, cybersecurity, artificial intelligence and digital literacy. The browser-based editor supports more than 10 languages, including Python, Java, JavaScript and C++. Classroom tools include autograders, in-editor help, code history and a blocks-to-text experience. Its learning management system gives teachers visibility into class progress, assignment grading and students' coding process. Listed AI features include hints, grading, Ask AI and Vibe Coding; the free-versus-Pro comparison identifies AI grading and hints as Pro features. The permanent Free teacher plan requires no credit card and has no per-student fees, but includes no downloads. Individual Learner All Access costs $99 a month, billed monthly, or $990 a year, billed annually. CodeHS says it is not an accredited school or online course provider, so Individual Learner students do not receive official grades or academic credit upon completion. Most integrations require a school license.

ScratchJr is a free introductory programming app for children ages 5–7 to create interactive stories and games. Children snap graphical blocks together to make characters move, jump, dance, and sing. They can edit characters in a paint editor, add voices and sounds, and include photos in projects. The app is designed to support young children's cognitive, personal, social, and emotional growth. ScratchJr is developed for iPads running iOS 10 or later and Android tablets running Android 5 or later; it may also run with limitations on some Chromebooks, Apple-silicon MacBooks, Fire tablets, and Windows 11 PCs. Devices that run it in a virtual container may have limits on importing and exporting projects. Projects, including their images and recordings, are stored on the device and are not sent to or accessible by Scratch. The privacy policy says the app collects use preferences and automatically gathers country-level IP and device information; it may also collect usage information such as time spent in the app. Projects can be shared by email, or by AirDrop on iPads. The site offers teacher-led activities and ScratchJr Connect, a free resource database.
