Coverity Static Analysis is a comprehensive code scanning solution that enables developers and security teams to deliver high-quality software in compliance with security, functional safety, and industry standards. It effectively uncovers complex defects across extensive codebases, identifying and resolving code quality and security issues that span multiple files and libraries. Coverity supports compliance with a wide range of standards, including OWASP Top 10, CWE Top 25, MISRA, and CERT C/C++/Java, providing built-in reports to track and prioritize issues. With the Code Sight™ IDE plugin, developers receive real-time results, including CWE information and remediation guidance, directly within their development environment, facilitating the integration of security into the software development life cycle without compromising developer velocity.

​PHPStan is an open source static analysis tool for PHP that identifies bugs in your codebase without the need for writing tests. It thoroughly scans your entire code, detecting both obvious and subtle issues, including those in rarely executed conditional statements that tests might not cover. By integrating PHPStan into your development environment and continuous integration pipelines, you can prevent bugs from reaching production. It is compatible with legacy codebases, even those lacking an autoloader, and facilitates gradual improvement through configurable rule levels. This approach allows developers to incrementally enhance code quality without being overwhelmed by numerous errors on the initial run. ​PHPStan supports advanced PHP features ahead of their official release, such as generics, array shapes, and checked exceptions, by leveraging PHPDocs. It also offers extensions for popular frameworks like Symfony, Laravel, and Doctrine, ensuring comprehensive understanding.
