freeCodeCamp vs ScratchJr

freeCodeCamp is a free community for people learning to code together. Learners build projects step by step in a browser, code editor, or mobile app, using a public curriculum of videos, articles, and interactive lessons. Topics include HTML, CSS, JavaScript, Python, Bash, SQL, and computer science. Its verified certifications are free and self-paced; each takes around 300 hours of dedicated learning, and learners may move between challenges instead of following them in order. The iOS and Android apps let users study on the go and sync progress with a freeCodeCamp account. A publication, YouTube channel, and forum extend the community’s learning resources. Users can sign in with GitHub or Google, make portfolio details private, download their data in JSON format, or delete personal data or their account. freeCodeCamp describes its project as open source under the BSD-3 license, and says educators can use its materials without a license or special permission. The resources are used by high school, college, and adult education programs.

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.
