Codacy

Codacy connects to repositories on GitHub, GitLab, and Bitbucket and analyzes code as it changes. It runs static analysis across many languages, checks for style problems, bugs, security issues, and complexity, and posts results as comments on pull requests. Teams can set quality gates that block merges when code does not meet agreed standards.

Dashboards show trends over time, including code coverage, duplication, and issue counts per repository, which helps engineering leads see whether quality is improving. Security features scan dependencies and secrets, and recent AI features suggest fixes and help review code produced by AI assistants. It integrates with CI systems and IDEs.

Codacy has a free tier for open-source and small teams, and paid plans per developer. Like all static analysis, it produces false positives and needs rules tuned to the team. Alternatives include SonarQube, Code Climate, DeepSource, Snyk Code, and GitHub’s built-in code scanning. Codacy suits teams that want automated quality checks in their pull request flow.
