Pick OpossumUI if…
It suits teams handling open-source inventories, license-compliance audits, SBOM work, or legal review. It is also relevant to blind acquisition audits where source code should remain undisclosed.
Pick SourceTrust if…
SourceTrust suits teams that need to review dependencies and publish license compliance information for shipped products. Eligible public GitHub projects may qualify for its free publishing option; it is software tooling, not legal advice.
