IntelliJ IDEA vs SnapCode

IntelliJ IDEA is an IDE for professional Java and Kotlin development, available on Windows, macOS, and Linux. It offers context-aware completion, static analysis, and automated refactoring. The JVM debugger includes breakpoints, variable inspection, expression evaluation, and step-by-step execution. Gradle and Maven integrations cover building, packaging, testing, and deployment, while version-control support includes Git, Mercurial, Perforce, and Subversion. Users can process GitHub pull requests in the IDE, and plugins from JetBrains Marketplace add support for other languages, frameworks, and technologies. Core Java and Kotlin functionality remains free after the included 30-day Ultimate trial ends. The Ultimate subscription adds advanced tools and integrations and costs $100.00 for the first year, $199.00 for the second year, and $159.00 per year from the third year onward. Listed minimum hardware is a 4-core x86_64 or arm64 CPU, 8 GB total RAM, and 10 GB of disk space. Users can choose in IDE settings whether to share anonymous usage data.

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.
