Clang Static Analyzer vs Codacy

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.

Codacy is a cloud platform for engineering teams focused on code quality, security, and AI coding standards. Its AI Reviewer reviews pull requests with fix suggestions and summaries, and can identify false positives automatically. Listed security capabilities include SAST, software composition analysis, secret scanning, infrastructure-as-code scanning, DAST, and container image scanning. Team offers shared coding standards across 49 languages, integrations for GitHub, Bitbucket, GitLab, Jira, and Slack, and capacity for up to 30 developers and 100 private repositories with unlimited lines of code. Developer includes an IDE plugin and integrations for VSCode, JetBrains, and Cursor; the IDE extension comparison also names Windsurf. Developer costs nothing. Team costs $18 a year with yearly billing or $21 a month with monthly billing, billed per developer per month. A 14-day free trial is available without a credit card. Codacy states that it is GDPR compliant and has SOC 2 Type II compliance; its services run on AWS, with data in transit encrypted using TLS.
