DejaCode vs FOSSology

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.

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.
