Code on the Go vs SnapCode

Code on the Go has no write-up on Specifiction yet; its figures are above.

SnapCode is a free Java IDE tailored for education, available in a browser and as a desktop app or executable JAR. It supports Java 11 and later on Windows, macOS, and Linux; the maker says the browser version runs in modern browsers. Projects can be worked on in the cloud, where SnapCloud saves local changes automatically by default, with manual synchronization available if autosave is disabled. Editing tools include syntax highlighting, type-aware completion, inline warnings and errors, project search, and navigation to declarations, JavaDocs, and source. An optional REPL evaluates snippets as they are typed without requiring class or main declarations, and can omit semicolons. SnapCode also provides drag-and-drop block coding and an integrated UI builder that stores interfaces in .snp XML files. SnapKit supports UI controls, vector graphics, image effects, animation, and 3D; SnapCharts includes six chart types. Users can share running apps and code or embed runnable, editable code in HTML pages. Java Markdown runs Java code in Markdown documents, but remains in development.
