FOSSology vs SBOM Workbench

FOSSology is an open-source system for examining software for license, copyright, and export-control information. Upload individual files or packages, then unpack and scan them with selected agents. Nomos looks for license indicators through phrases, regular expressions, and heuristics; Monk checks text against stored license texts or phrases supplied by users. Its web interface supports review of findings, license-text management, bulk recognition, aggregated file views, and reusing reviews for files with matching hashes. It can identify copyright statements and presents keyword-based findings that users can review for possible export-control relevance. Reports include SPDX 2.0 exports, Debian copyright files, hierarchical file lists with license identifiers, and Readme files with identified license and copyright details. A REST API supports CI/CD use, uploads, and scan triggers from other applications; the command line can retrieve SPDX files. Deployment options include Docker, Vagrant with VirtualBox, or source installation. It is free, with on-premise deployment options. One stated limit: it cannot determine which libraries produced a binary; binary analysis tools are needed for that task.

SBOM Workbench is a graphical tool for scanning and auditing source code through the SCANOSS API. It identifies open-source components, including undeclared code that may not appear in dependency manifests, and the free version identifies licenses and security vulnerabilities. It generates SPDX-Lite software bills of materials; release notes also list CycloneDX, SPDX Lite, CSV, and HTML exports. The tool is aimed at developers and runs on Linux, macOS, and Windows. Its CLI can use multiple SCANOSS API endpoints, including custom servers. Listed integrations include pre-commit hooks, Actions, pipelines, and webhooks, while Bitbucket is marked as coming soon. Repository documentation describes a collaborative workspace. The distributed software is described by SCANOSS as open source, and the Workbench has a public GitHub repository. Cryptographic algorithm identification is a premium feature, not included in the free Workbench. It is free to download, and SCANOSS directs support requests to email. Paid SCANOSS subscription prices listed for other offerings are not Workbench prices.
