Cppcheck is an open-source static analysis tool for C and C++ code that detects bugs, undefined behavior, and dangerous coding constructs with a focus on very few false positives. It is available as both a command line tool and a GUI application, and can analyze code even with non-standard syntax common in embedded projects.

Use cases

• find bugs in my C/C++ code before compiling
• detect undefined behavior in C++ projects
• static analysis for embedded C code with non-standard syntax
• add a C/C++ linter to my CI pipeline
• check for memory leaks and out-of-bounds errors in C++
• analyze a large C codebase for dangerous coding constructs

When to choose

• you need a fast, low-false-positive static analyzer for C or C++
• your codebase has non-standard or embedded-specific syntax
• you want a free, cross-platform analyzer with CLI and GUI options
• you want to complement other analyzers like clang-tidy with unique bug detection

When to avoid

• you need path-sensitive abstract-interpretation analysis with formal soundness guarantees
• you need static analysis for languages other than C/C++
• you want fully automated fixes rather than diagnostics
• you require commercial support and extended functionality out of the box
