CodeChecker vs CPAchecker

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.

CPAchecker is a configurable software verification tool based on configurable program analysis concepts. It accepts C and SV-LIB inputs, lists predicate analysis for SV-LIB programs, and supports invariants, counterexamples, and proof artifacts. It can also validate termination witnesses in YAML formats 2.1 and 1.0. The project lists a hybrid verification method and provides a self-hosted deployment. CPAchecker is free software under the Apache 2.0 License. Version 4.2.2, released in December 2025, is available as Unix and Windows ZIP archives; Debian and Ubuntu users can install it from the SoSy-Lab APT repository, and a Docker image is available. Java 21 or later is required as of version 4.2. An older version, 1.6.1, can be accessed through a web interface, where some functions are unavailable in the restricted environment. Documentation includes installation instructions, tutorials, and getting-started guidance. Installation questions, bug reports, and suggestions can go to the users mailing list or issue tracker. The project is based in Munich, Germany.
