## What it is
The OSS Review Toolkit (ORT) is a FOSS policy automation toolkit that analyzes project dependencies, scans licenses and copyrights, checks security vulnerabilities, and generates SBOMs (SPDX, CycloneDX) and attribution documents. It can be used as a library, CLI, or CI integration and combines tools like Analyzer, Downloader, Scanner, and Advisor into customizable pipelines.

## Use cases
- generate spdx or cyclonedx sbom for my project
- automate open source license compliance checks in ci
- create attribution documents for third-party dependencies
- scan dependencies for security vulnerabilities
- check licenses and copyrights of npm and maven dependencies
- enforce foss policy as code across repositories
- archive source code of all dependencies for license compliance

## When to choose
- you need automated license, copyright, and vulnerability compliance across many package managers
- you must produce SBOMs or attribution docs for regulatory or customer requirements
- you want policy-as-code enforcement in CI pipelines

## When to avoid
- you only need a quick one-off license scan without pipeline setup
- you need a lightweight GUI-only tool rather than a configurable toolkit
- your project uses package managers not supported by ORT's analyzer
