What is Free Static Code Analysis Software?

Static code analysis software is software designed to examine source code for potential errors, vulnerabilities, and code quality issues without executing the program. It scans the code to detect syntax problems, security flaws, and non-compliance with coding standards. This type of software helps developers identify bugs early in the development process, improving code reliability and reducing debugging time later. Static code analysis also assists in maintaining code consistency across teams by enforcing best practices and coding guidelines. By automating the review process, the software enhances code quality, reduces technical debt, and contributes to more secure, maintainable software. Compare and read user reviews of the best Free Static Code Analysis software currently available using the table below. This list is updated regularly.

PlatformIO

PlatformIO

Professional collaborative platform for embedded development. PlatformIO is a next-generation, collaborative platform for embedded development that enables customers to save resources and time by vastly reducing the expenses and labor associated with creating and maintaining product software. We believe the embedded systems industry desperately needs reinvention. Not only are the IDEs and tools built with technology from the 1990s, but they involve many complex requirements and platform-dependent configurations that turn away talented developers from becoming embedded engineers. The most loved IDE solution for Microsoft Visual Studio Code. A user-friendly and extensible integrated development environment with a set of professional development instruments, providing modern and powerful features to speed up yet simplify the creation and delivery of embedded products. PlatformIO is written in pure Python and doesn't depend on any additional libraries/tools from an operation system.

Brakeman

Brakeman

Brakeman is a security scanner for Ruby on Rails applications. Unlike many web security scanners, Brakeman looks at the source code of your application. This means you do not need to set up your whole application stack to use it. Once Brakeman scans the application code, it produces a report of all security issues it has found. Brakeman requires zero setup or configuration once it is installed. Just run it. Because all Brakeman needs is source code, Brakeman can be run at any stage of development: you can generate a new application with rails new and immediately check it with Brakeman. Since Brakeman does not rely on spidering sites to determine all their pages, it can provide more complete coverage of an application. This includes pages which may not be ‘live’ yet. In theory, Brakeman can find security vulnerabilities before they become exploitable. Brakeman is specifically built for Ruby on Rails applications, so it can easily check configuration settings for best practices.
