weblint.

Syntax and minimal style checker for HTML.

lintsh.

Lintsh is a Bourne shell that optionally warns about suspicious or nonportable constructs.

Valgrind.

Runs programs on a virtual processor and can detect memory errors (e.g., misuse of malloc and free) and race conditions in multithread programs.

Dmalloc.

Dmalloc is a memory debugger C library.

Avalanche.

Avalanche is a dynamic defect detection tool that generates "inputs of death" - input data reproducing critical bugs and vulnerabilities in the analysed program.

PMD.

PMD is a static ruleset based Java source code analyzer that identifies potential problems.

PMD has plugins for JDeveloper, Eclipse, JEdit, JBuilder, Omnicore's CodeGuide, NetBeans/Sun Studio, IntelliJ IDEA, TextPad, Maven, Ant, Gel, JCreator, Hudson, Jenkins, Sonar and Emacs.

JSLint.

JSLint is a static code analysis tool used in software development for checking if JavaScript source code complies with coding rules.

It is provided primarily as an online tool, but there are also command-line adaptations.

Squale.

Squale (Software Quality Enhancement) is an open-source platform that helps monitoring software quality for multi-language applications. It currently supports Java out-of-the-box, and can also analyse C/C++ and Cobol code with an adapter to McCabe tool. Squale is distributed under the terms of the LGPL v3 licence.

Yasca.

Yasca leverages external open source programs, such as FindBugs, PMD, JLint, JavaScript Lint, PHPLint, Cppcheck, ClamAV, Pixy, and RATS to scan specific file types, and also contains many custom scanners developed for Yasca.
