Hedy

Hedy is a free, open-source, browser-based programming language and learning platform for teachers, schools, and learners aged 10+ who want to start with textual programming.

Key features include:

• Gradual, level-based learning that introduces concepts with minimal syntax first, then progresses toward a subset of syntactically valid Python
• Multilingual programming in 47 languages, letting students code with keywords in their native language instead of English
• Classroom-focused teaching tools, including built-in lesson plans, the ability to create custom lessons, and teacher resources such as a teacher’s manual and concept explanations
• Creative, project-based outputs, including interactive stories, drawings, games, and apps (with options for visual and physical outputs like pen plotter drawings or embroidered designs)

Pricing: Free.

What makes it notable is its combination of multilingual syntax and step-by-step scaffolding for textual programming, plus classroom management features that help educators teach coding without requiring prior programming experience. It runs entirely in the browser on desktops, phones, and tablets, with no installation required.
