Licenses
Detect open source licenses, understand obligations, generate attribution, and track your compliance posture.

Overview
Every open source dependency you ship carries license obligations: attribution, source disclosure, copyleft, and more. FOSSA identifies the licenses across your dependency tree and source, surfaces what each one requires, and helps you stay compliant.
What this covers
- Understanding licensing issues: how FOSSA detects declared and discovered licenses and why an issue is raised.
- Reviewing licensing issues: work through your licensing backlog with bulk actions and triage.
- License corrections and conclusions: override or finalize the license FOSSA records for a package.
- License disputes: resolve disagreements about what a dependency is actually licensed under.
- Custom license scans: detect your own proprietary or third-party license text.
