CodeFactor

CodeFactor is an automated code review and quality analysis platform that grades every commit and pull request on GitHub and Bitbucket.

Overview

CodeFactor automatically reviews your code for quality issues, duplications and style violations every time you push. It grades repositories and individual files, annotates pull requests with findings, and tracks quality trends over time so teams can see whether the codebase is improving or decaying. Support spans dozens of languages with configurable style rules, and the free tier for open-source projects has made it common across public repositories. It is lightweight, fast and requires no build integration — connect a repo and analysis starts.
