CodeChecker vs Flawfinder

CodeChecker is free, open-source static-analysis infrastructure built on LLVM and Clang Static Analyzer tooling. Its command-line tools run supported analyzers against a JSON compilation database and generate reports. The web interface stores, filters, compares, and visualizes findings, including code bug paths, while reviewers can comment and set status. Reanalysis can be limited to changed files and their dependencies. Listed language coverage includes C/C++, C#, Java, Python, JavaScript, TypeScript, Go, and Markdown. Integrations cover Gerrit, GitLab, and a reusable GitHub Actions workflow. A Visual Studio Code extension runs analysis, reanalyzes saved files, and browses reports. Servers can run locally or in Docker, with PostgreSQL or SQLite storage and configurable authentication. CodeChecker requires Python 3.11 or later.

Flawfinder is a free tool for finding possible security weaknesses in C and C++ source code. It compares source text with a built-in database of functions associated with security problems, generally disregarding comments and strings except for Flawfinder directives. Findings are ordered by risk, which depends on the function and its parameter values; the tool may reduce some false positives when it identifies a construct as not risky. Reports can be generated as text, HTML, CSV, or SARIF. The --patch option narrows findings to changed lines in a unified diff, with a one-line margin. Installation is documented through pip, source downloads, and distribution packages, and the tool requires Python 2.7 or Python 3. The project says it works on Unix-like systems, including GNU/Linux, and on Windows with Cygwin; direct Windows use has also been reported to work. Flawfinder is released under GPL-2.0+. It does not perform control-flow or data-flow analysis, so its output is an aid to review rather than a substitute for security knowledge or human judgment.
