CodeHS vs Scratch

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.

Scratch is a free programming platform for making and sharing interactive stories, games and animations. Its visual projects are built with Scratch, and project-based learning aims to develop creative thinking, systematic reasoning and collaboration. It is designed especially for ages 8 to 16, though people of all ages use it. Scratch runs on the web and on Android, macOS and Windows; app downloads are listed for Windows 10+, macOS 10.13+, ChromeOS and Android tablets running Android 6.0+. The app works offline, but projects made offline are not accessible by Scratch. Extensions add blocks for connecting projects to hardware or web services. Scratch says it is used in more than 150 countries and is available in more than 40 languages. The platform is free. Optional Annual Membership is $35 a year, and Lifetime Membership is $150, paid once; both are donations that include early or exclusive content, tutorials, merchandise and store discounts.
