DejaCode vs OSSKB

DejaCode is an enterprise application for managing open-source license compliance and software supply-chain integrity across products and teams. It tracks open-source and third-party components, with unlimited products, components, and packages in each plan. Teams can store and manage SBOMs, retain historical records for audits, and import CycloneDX, SPDX, or AboutFile formats. Usage policies can be set at license or package level and linked with ScanCode; enforcement is advisory. Integrations include GitHub, GitLab, Jira Cloud, SourceHut, and Forgejo, with REST API and webhook options for other services. AboutCode connections include ScanCode.io for package scanning, PurlDB, and VulnerableCode for vulnerability data. Deployment documentation covers Docker, enterprise, and local development setups. For enterprise deployments, the guidance recommends running your own related service instances to avoid sending sensitive or private data to public endpoints. Team starts at $500 a month and Business at $1,500 a month, each billed annually at the start of the subscription period. Enterprise pricing is custom and not listed. A private evaluation instance with all features and support is available for 30 days.

OSSKB identifies open source software in source code, including at the snippet level, to provide information relevant to license compliance. It matches source-code fingerprints against a database of fingerprints for known open source software. Results may include license names, copyright statements, quality indicators, and vulnerability information. The web service also offers API access, a Python scanner, and Audit Workbench downloads for macOS Intel, macOS M1/M2, and Linux; a compatible CLI or webhook can support automation. OSSKB is powered by the Open Source Software Knowledge Base, created and maintained by SCANOSS. It is free of charge on a best-effort basis, with no guarantee of availability or performance. The provider may limit the number or frequency of transactions to help maintain availability and performance. Fingerprint matching can produce false positives and false negatives, so results need human assessment. The terms say usage information may be logged to monitor load and improve the service, and that OSSKB is designed for professional use rather than end consumers. The listed plan is free.
