Clang Static Analyzer vs CodeChecker

Clang Static Analyzer finds selected bugs in C, C++, and Objective-C programs. It uses symbolic execution to examine paths through code across function calls, and is part of the open-source Clang project. The analyzer is also implemented as a reusable C++ library for other tools and applications. Official releases include scan-build, a command-line tool for analyzing a codebase. On macOS, users can invoke it from Xcode; it can also run alongside clang-tidy when clang-analyzer checks are enabled. Clang-based IDEs may integrate the analyzer directly, and the documentation covers scan-build and CodeChecker. It runs on Linux, macOS, and Windows, and is self-hosted. The tool only detects bugs it has been designed to find, and analysis can take much longer than compilation. Some algorithms have exponential worst-case time, and results may include false positives. The listed free plan costs nothing.

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.
