Code.org Web Lab
What Code.org Web Lab is
Code.org Web Lab is a free browser-based environment where students build interactive websites and apps with HTML, CSS, and JavaScript, with an AI Tutor as a coding co-creator. It is intended for beginner middle and high school students ages 13–18. The tutor can explain concepts, produce code, suggest changes, and help debug; students can review suggestions and decide whether to accept them. It uses Gemini Flash 2.5, while ChatGPT 4o Mini moderates messages in both directions.
Web Lab can be used independently or with the CodeAI curriculum. Sketch Lab lets students plan designs that can inform Web Lab projects, but is only available within the AI Foundations curriculum. Web Lab focuses on local HTML, CSS, and JavaScript files, with external libraries and imports limited. It works in modern browsers on laptops and Chromebooks and supports keyboard and screen-reader access. Teachers must be verified and enable AI Tutor before students can use it. AI interactions are deleted after 90 days and are not used to train third-party models.
