ScanCode Toolkit is a set of code scanning tools that detect the origin (copyrights), license and vulnerabilities of code, packages and dependencies in a codebase. ScanCode Toolkit is an AboutCode project.

ScanCode Toolkit is the leading tool in scanning depth and accuracy, used by hundreds of software teams. You can use ScanCode Toolkit as a command line tool or as a library.

Instructions to get you up and running on your local machine are at Getting Started

The ScanCode Toolkit documentation also provides:

• prerequisites for installing the software.
• instructions guiding you to start scanning code.
• a comprehensive guide to the command line options.
• tutorials that provide hands-on guidance to ScanCode features.
• how to expand ScanCode Licenses and Detection Rules with your own data.
• how to generate Attribution from a ScanCode scan.
• guidelines for contributing to code development.

We run 30,000+ tests on each commit on multiple CIs to ensure a good platform compabitility with multiple versions of Windows, Linux and macOS.

• ScanCode is heavily tested with an automated test suite of over 30,000 tests.
• ScanCode is used by several projects and organizations such as the Eclipse Foundation, OpenEmbedded.org, the FSFE, the FSF, OSS Review Toolkit, ClearlyDefined.io, RedHat Fabric8 analytics, and many more.
• You can also organize and run ScanCode server-side with the companion ScanCode.io web app to organize and store multiple scan projects including scripted scanning pipelines.
• As a standalone command-line tool, ScanCode is easy to install, run, and embed in your CI/CD processing pipeline. It runs on Windows, macOS, and Linux.
• ScanCode detects licenses, copyrights, package manifests, direct dependencies, and more both in source code and binary files and is considered as the best-in-class and reference tool in this domain, re-used as the core tools for software composition data collection by several open source tools.
• ScanCode provides the most accurate license detection engine and does a full comparison (also known as diff or red line comparison) between a database of license texts and your code instead of relying only on approximate regex patterns or probabilistic search, edit distance or machine learning.
• Written in Python, ScanCode is easy to extend with plugins to contribute new and improved scanners, data summarization, package manifest parsers, and new outputs.
• You can save your scan results as JSON, YAML, HTML, CycloneDX or SPDX or even create your own format with Jinja templates.
• ScanCode can process packages, build manifest and lockfile formats to collect Package URLs and extract metadata. See all available package parsers for the exhaustive list.

If you have a specific problem, suggestion or bug, please submit a GitHub issue.
