# List of tools for static code analysis

EDITORS, PLEASE NOTE:
This article is covered under Wikipedia's [[Wikipedia:Manual of Style/Stand&#x2D;alone lists|guidelines for standalone lists]]. This means that the only tools that should be listed here are ones that have their own articles on Wikipedia. This is not the place to have external links to a tool's homepage or anything like that. Tools that fail to meet this criteria (of having an article) may be deleted per our guidelines. If the tool has no article, consider [[WP:WTAF|writing one first]].
This is a list of notable tools for static program analysis (program analysis is a synonym for code analysis).

## Formal methods tools

Tools that use sound, i.e. over-approximating a rigorous model, formal methods approach to static analysis (e.g., using static program assertions). Sound methods contain no false negatives for bug-free programs, at least with regards to the idealized mathematical model they are based on (there is no "unconditional" soundness). Note that there is no guarantee they will report all bugs for buggy programs, they will report at least one.
* Astrée – finds all potential runtime errors by abstract interpretation, can prove the absence of runtime errors and can prove functional assertions; tailored towards safety-critical C code (e.g. avionics).
* CodePeer – Statically determines and documents pre- and post-conditions for Ada subprograms; statically checks preconditions at all call sites.
* ECLAIR – Uses formal methods-based static code analysis techniques such as abstract interpretation and model checking combined with constraint satisfaction techniques to detect or prove the absence of certain run time errors in source code.
* ESC/Java and ESC/Java2 – Based on Java Modeling Language, an enriched version of Java
* Frama-C – An open-source analysis framework for C, based on the ANSI/ISO C Specification Language (ACSL). Its main techniques include abstract interpretation, deductive verification and runtime monitoring.
* KeY – analysis platform for Java based on theorem proving with specifications in the Java Modeling Language; can generate test cases as counterexamples; stand-alone GUI or Eclipse integration
* MALPAS – A formal methods tool that uses directed graphs and regular algebra to prove that software under analysis correctly meets its mathematical specification.
* Polyspace – Uses abstract interpretation, a formal methods based technique, to detect and prove the absence of certain run time errors in source code for C/C++, and Ada
* SPARK Toolset including the SPARK Examiner – Based on the SPARK language, a subset of Ada.
