In their own words
ReSharper
ReSharper provides coding assistance and code quality tools for.NET development. It analyzes C#, VB.NET, XAML, ASP.NET, HTML, and XML as code is written. Editing features include extended IntelliSense, transformations, namespace imports, code rearrangement, and documentation display. Developers can generate properties, overloads, implementations, and comparers, then apply refactorings across a solution or to smaller sections. Navigation helps move among files, types, and members, and follow symbols to usages, base or derived symbols, and implementations. Other tools include a unit test runner, code templates, debugging assistance, project dependency viewing, and internationalization assistance. The VS Code edition also works with Cursor, Antigravity IDE, Devin Desktop, Kiro IDE, and compatible editors. It runs on Windows, macOS, and Linux on x64 and ARM64, including Apple silicon on macOS, and requires a.NET SDK version 6.0 or later on PATH. A 30-day trial starts after installation. Afterward, use requires a commercial license or a free non-commercial license. The commercial plan costs $389 a year per user.
Spoon
Spoon is a free, open-source library for analyzing, rewriting, transforming, and transpiling Java source code. It parses source files into an abstract syntax tree (AST), then exposes APIs for inspecting and changing that model. Processors can perform source-level static analysis on selected AST element types, while architectural rules can be expressed as AST checks and run as JUnit tests in continuous integration. Transformation facilities cover instrumentation and refactoring, including helpers for local and generic variables and removing deprecated methods. Spoon can also provide shared analysis of binary and source code through CtClass objects as an alternative to Java reflection. The project supports Java source up to Java 25, but runtime requirements vary: Spoon 11.x needs JDK 17 or later, 10.x needs JDK 11 or later, and 9.x needs Java 8. It is available through Java, the command line, Maven, and Gradle, with a dependency JAR on Maven Central. Command-line use requires manual classpath handling and source dependencies specified with --source-classpath. Spoon is an official Inria project and an OW2 consortium member.
