Show HN: Harbor Guard – Manage and Scan Container Images (Open Source)

Hey HN, I’m Brandon, developer for Harbor Guard, an open-source container security platform that unifies multiple scanning tools into a single intuitive dashboard.

Over the past month, I got tired of juggling different CLI scanners (Trivy, Grype, Syft, Dockle, etc.), for my work in DevSecOps. Stitching results together started becoming a hassle and my organization started heavily focusing on container security. It was messy, repetitive, and hard to keep track of active vulnerabilities.

So I built Harbor Guard, a modern, Next.js app that runs all major open-source container scanners, stores the results, and turns them into interactive visualizations you can actually use.

What Harbor Guard does:

- Runs 6 major tools: Trivy, Grype, Syft, Dockle, OSV Scanner, and Dive

- Unified dashboard: View and compare results without jumping between CLIs

- Historical tracking: Persist and compare scans across versions

- Advanced visualization: Interactive scatterplots, severity-based grouping, and layer-by-layer analysis

- Report export: Grab JSON or full ZIP packages for compliance

- API access: REST endpoints for automation and integrations

- Docker-native: Run it with a single docker run -p 3000:3000 …

Personally, I needed a tool that made vulnerability data easier to explore visually and had some fun putting something together.

It’s free, open source, and I’d love feedback, bug reports, or feature ideas. Contributions welcome too.

Thanks, Brandon
