FOSSology vs ScanCode.io

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.

ScanCode.io provides a web interface and API for running software composition analysis scans in scripted pipelines. It scans containers, Docker images, package archives, and manifests for license, copyright, source, and vulnerability information, and can generate or consume CycloneDX and SPDX SBOMs. The same capabilities are available through its command-line interface and REST API. Documented pipeline integrations include GitHub Actions, Jenkins, GitLab, and Azure Pipelines; other CI/CD systems that support Docker can run it too. It can fetch packages using Package URLs and retrieve artifacts from JFrog Artifactory and Sonatype Nexus. Installation is preferably through Docker, including for Windows; Linux server installation is also supported, and an offline Docker package can be transferred to an isolated server. The software is open source under Apache License 2.0 and is free. Authentication for the web interface and API is disabled by default, but can be enabled. Its default setup starts one worker, so it runs one pipeline at a time.
