Open-source vulnerability static analysis tool for container images (OCI/Docker) via API-based indexing and matching.
Clair is an open-source vulnerability static analysis tool for container images, supporting OCI and Docker formats. It allows users to index container images via its API and match them against databases of known vulnerabilities to identify security risks. The project aims to provide a transparent view of security in container-based infrastructure.
DevOps engineers, security teams, and developers managing containerized applications who need to scan images for vulnerabilities as part of CI/CD pipelines or security audits.
Clair offers a specialized, API-driven approach to container vulnerability scanning that integrates easily into automated workflows, with a focus on transparency and compatibility with major container formats.
Vulnerability Static Analysis for Containers

Clair performs offline scanning of container images without executing them, efficiently identifying known vulnerabilities from databases, as highlighted in its static analysis approach.
It supports both OCI and Docker image formats, covering the major specifications used in container ecosystems, ensuring compatibility with standard tools.
With its API-driven indexing, Clair allows seamless integration into CI/CD pipelines and custom security tooling for automated workflows, as emphasized in the README.
As an open-source project under Apache 2.0, Clair provides full visibility into its scanning process and vulnerability data, aligning with its goal of transparent security.
The main branch can be unstable or broken during development, requiring users to rely on releases for stable binaries, which may delay access to new features.
Being self-hosted, Clair requires deployment, configuration, and ongoing updates to vulnerability databases, demanding significant operational resources and expertise.
Clair lacks a graphical user interface, making it less accessible for non-technical users and necessitating custom front-ends for visualization and reporting.
As a static scanner, it cannot detect vulnerabilities that depend on runtime conditions or specific container behaviors, missing dynamic security issues.
