In their own words
Cppcheck
Cppcheck is a static analysis tool for C and C++ code that detects bugs, undefined behavior, and dangerous coding constructs. It can analyze non-standard syntax commonly found in embedded projects. The tool fully supports C++11, C++14, and C++17, with partial support for C++20, and lists integrations with Visual Studio, VSCode, Keil, Eclipse, CLion, Qt Creator, and C++ Builder. Its Soundy mode is intended to help find hard-to-find bugs discovered during testing. The free Open-source plan provides core static analysis. Premium adds checks for safety and security standards, with compliance reports for supported standards; the maker describes Premium as TÜV SÜD certified for safety-critical development. A three-week free trial is offered without a credit card or commitment. Individual licensing excludes CI environments, virtual machines, and containers, while Enterprise supports those environments and air-gapped use. Project requires at least five users and one Git repository. Paid plan prices are available by tailored quotation.
