Cppcheck — Cppcheck is an open-source static analysis tool for C and C++ code. It helps identify bugs, structural issues, and security flaws in your code.

Clang Static Analyzer offers Detects memory leaks, Finds null pointer dereferences, Warns about potential security vulnerabilities, Performs taint analysis to track untrusted data, Does control and data flow analysis, while Cppcheck provides Static analysis of C/C++ code, Detects bugs like null pointer dereferences, use of uninitialized variables, etc, Detects unused functions and variables, Checks for code style issues, Cross-platform support.

Clang Static Analyzer stands out for Finds bugs at compile time without running code, Open source and free to use, High precision warnings with low false positive rate; Cppcheck is known for Free and open source, Easy integration with build systems, Fast analysis.
