Block Editor Studio

This tool is a browser-based, Scratch-like block editor designed for education and rapid prototyping of visual programs. It enables learners to start from a template or a blank project, assemble scripts by dragging and snapping blocks, and run a runtime sandbox to observe outcomes without installing software. Projects are stored locally by default and can be exported as JSON for version control, sharing, or backup. The environment is suited for classrooms, after-school programs, and self-guided learners who value immediate feedback.
Conceptually, programs are represented as a graph of blocks that encode sequences, events, and control flow. The internal model maps this graph to an executable structure, while the runtime schedules block execution, handles events, and records state snapshots. Extensions can introduce new blocks and sensor integrations, allowing projects to interact with external data sources. Extensions and Scratch-compatible JSON interchange ease sharing with other tools.
Audience and value: Educators gain a private, installation-free workspace to demonstrate core concepts, assess student work, and prototype lesson plans. Students practice sequencing, debugging, and creative problem solving in a low-friction environment. Unique differentiators include in-browser execution without setup, emphasis on educational workflows, support for extensions, and ability to export/import projects for collaboration or assessment.
Core features and use cases: A draggable palette, script workspace, project metadata, and a sandbox runtime provide a complete workflow from creation to testing. Use cases include classroom demonstrations, remote learning assignments, after-school clubs, and rapid prototyping of simple games or animations. The tool emphasizes privacy (local storage by default), cloud options for schools, and diagnostics to aid instructors in monitoring progress and addressing misconceptions.
