Sonar - Code quality for all languages
Sonar is an open platform to manage code quality. As such, it covers the 7 axes of code quality: Design, Code duplication, Unit test, Code complexity, Potential bugs, Coding rules, Comments. It has support for multiple languages like .NET, PHP, Java etc.
Sonar has more than 600 coding rules, provides standard metrics like Lines of Code, Cyclomatic Complexity, Duplicated code. It provides code coverage results for associated Unit test. It has hosted online metrics for open source projets http://nemo.sonarsource.org/.

Panopticode - Gathers, Correlats, and displays code metrics
The Panopticode project provides a set of open source tools for gathering, correlating, and displaying code metrics. It evaluates software quality and ensures coding standards. It installs and configures set of tools like Emma or Cobertura for unit test code coverage, Checkstyle to validate the coding standards, JDepend to check the dependency, JavaNCSS for Cyclomatic Complexity metrics.
Cobertura - Code coverage tool
Cobertura is a Java tool that calculates the percentage of code accessed by tests. It can be used to identify which parts of your Java program are lacking test coverage. it instruments Java bytecode after it has been compiled. Reports are generated in HTML and XML. It shows cyclomatic code complexity of each class, and the average cyclomatic code complexity for each package and for the overall product.
JavaNCSS - A Source Measurement Suite for Java
JavaNCSS is a simple command line utility which measures two standard source code metrics for the Java programming language. The Cyclomatic Complexity metrics are collected globally, for each class or for each function. It is also integrated with Ant task. NCSS means Non Commenting Source Statements, Source code except comments will be used for metrics calculation.
CodeNarc - Static Analysis for Groovy
CodeNarc analyzes Groovy code for defects, bad practices, inconsistencies, style issues, coding standards, best practices and more. CodeNarc triggers violations based on rules which are predefined or custom rules. The static analysis report is generated in XML or HTML format. It is well integrated with the Ant Task and plugins exist for Maven, Gradle, Grails, Griffon, Sonar and Hudson.
EMMA Java code coverage tool
EMMA is an open-source toolkit for measuring and reporting Java code coverage. EMMA can instrument classes for coverage either offline (before they are loaded) or on the fly (using an instrumenting application classloader). The coverage stats are aggregated at method, class, package, and "all classes" levels. EMMA can instrument individial class files or entire jars.
Checkstyle - checks Java coding standard
Checkstyle is a tool to help programmers write Java code that adheres to a coding standard. Checkstyle is highly configurable and can be made to support almost any coding standard. Checkstyle provides checks that find class design problems, duplicate code, or bug patterns like double checked locking. This tool could be integrated as Ant task.
JSLint - The JavaScript Code Quality Tool
JSLint is a JavaScript program that looks for problems in JavaScript programs. It is a code quality tool. JSLint takes a JavaScript source and scans it. If it finds a problem, it returns a message describing the problem and an approximate location within the source. The problem is not necessarily a syntax error, although it often is. JSLint looks at some style conventions as well as structural problems. It does not prove that your program is correct.
