What Code.org App Lab is

Code.org App Lab is a browser-based environment for making simple applications. Users write JavaScript with blocks or text, create interface screens in Design Mode, and share projects through the tool.

Curriculum activities can pair App Lab with BBC micro:bit and Adafruit Circuit Playground devices. The page lists beginners aged 13 through 18 and curriculum for grades 8 through 12. App Lab works in modern browsers on laptops, Chromebooks, and tablets. Listed accessibility support includes text-to-speech, closed captioning, and Immersive Reader, with English as the supported language. The service is free, with no paid plans or usage limits listed.
