| Deployment | The setup guide starts the GUAC server using Docker Compose and lists Docker, Docker Compose, and jq as prerequisites. | The site describes on-premise, fully air-gapped, and SaaS deployment options; on-premise and air-gapped deployments keep source, binaries, and build records inside the customer network. |
| Purpose | GUAC ingests software metadata such as SBOMs and maps relationships between software to provide supply chain security insights. | Strig monitors firmware builds, records inputs, compile and link events, and outputs, then produces risk findings and signed audit evidence. |

In their own words
GUAC
GUAC ingests software metadata, including software bills of materials, and connects it into a queryable view of supply-chain relationships. That portfolio-level view lets developers, operations and security practitioners, and Open Source Program Offices examine dependencies across software rather than one SBOM at a time. Teams can look for vulnerable, deprecated, unsupported, or duplicated dependencies and identify risky upstreams using OpenSSF Scorecard. APIs and a visualization tool support queries and exploration. GUAC documents SPDX and CycloneDX SBOM formats, with graph enrichment from OSV for vulnerability data, ClearlyDefined for license information, and Deps.dev for dependency information. Its GraphQL server can use in-memory storage or PostgreSQL for persistence. Collectors can read or watch files, storage buckets, and Git repositories; the filesystem collector is stable, while other collectors are experimental. Setup uses Docker Compose and requires Docker, Docker Compose, and jq. The project is an OpenSSF Incubating Project. GUAC is free and open source: its code is under the MIT license, and documentation content is under CC BY 4.0.
