CodeHS

CodeHS is a K-12 computer science education platform that gives schools everything they need to teach coding: a browser-based coding environment, a full standards-aligned curriculum spanning elementary through AP, teacher tools for grading and progress tracking, professional development, and industry certifications. Founded in 2012 by two Stanford CS section leaders, Jeremy Keeshin and Zach Galant, it now reaches millions of students and thousands of schools, and in 2025 acquired the K-8 creative coding platform Tynker.
