osv-ui dashboard

osv-ui

A beautiful, zero-config visual CVE dashboard for npm, Python, Go, Rust, Java, PHP, and Ruby projects.
One command. No signup. No API key. Runs 100% locally — your code never leaves your machine.

The problem

hljs language-bash

$ npm audit

# ... 300 lines of this ...
# moderate  Regular Expression Denial of Service in semver
# package   semver
# patched in >=7.5.2
# ...
# 12 vulnerabilities (3 moderate, 6 high, 3 critical)

Nobody reads that. Security gets ignored. Dependencies stay vulnerable.

The solution

hljs language-bash

npx osv-ui

→ Opens a dashboard. Every CVE, every fix, all your services. Done.

Why give it a try?

Zero-config: No complex setup, no signup, no API key required.

Fast & Visual: Real-time Risk Scores, vulnerability charts, and clear upgrade guides in seconds.
Multi-platform: Native support for Node.js (npm), Python, Go, Rust, Java, PHP, and Ruby.

Quick start

Scan current directory:

hljs language-bash

npx osv-ui

Scan a monorepo (multiple services at once):

hljs language-bash

npx osv-ui ./frontend ./api ./worker ./ml-service

Auto-discover all services under the current directory:

hljs language-bash

npx osv-ui -d

Add to your package.json scripts:

hljs language-json

{
  "scripts": {
    "audit:ui":  "npx osv-ui",
    "audit:all": "npx osv-ui ./frontend ./api ./worker"
  }
}

hljs language-scss

--discover, -d    Auto-find service dirs that contain a supported manifest
--port=2003       Use a custom port (default: 2003)
--json[=file]     Save report as JSON without opening browser (defaults to osv-report.json)
--html[=file]     Save report as HTML without opening browser (defaults to osv-report.html)
--cyclonedx[=file] Save CycloneDX SBOM JSON (defaults to osv-sbom.cdx.json)
--spdx[=file]     Save SPDX SBOM JSON (defaults to osv-sbom.spdx.json)
--baseline=file   Compare with a previous --json report
--markdown[=file] Save a Markdown PR/comment report (defaults to osv-report.md)
--fail-on=level   Exit non-zero for critical/high/moderate/low findings
--webhook-url=url POST matching findings to a webhook
--webhook-severity=level Webhook threshold (default: critical)
--watch           Keep dashboard running and re-scan when manifests change
--no-open         Don't auto-open the browser
--offline         Skip OSV.dev lookup — parse manifests only
-h, --help        Show help message

🤖 AI Agent Integration (MCP)

osv-ui is now a Model Context Protocol (MCP) server. This allows AI agents like Claude Desktop, Cursor, and Claude Code to:

Scan your project for CVEs automatically.
Open the visual dashboard for you to review findings (Human-in-the-loop).
Apply fixes after your explicit confirmation.

Quick setup (npx):

hljs language-json

{
  "mcpServers": {
    "osv-ui": {
      "command": "npx",
      "args": ["-y", "osv-ui-mcp"]
    }
  }
}

See the MCP Package README for detailed setup instructions.

🔌 Powerful built-in API

osv-ui isn't just a dashboard; it's a security data engine.
Once the dashboard is running, you can pull the raw security data for your whole project:

hljs language-bash

# Get full JSON payload for all services
curl http://localhost:2003/api/data

# Use it in your custom scripts
curl -s http://localhost:2003/api/data | jq '.[0].vulns'

CI reports, PR diffs, and SBOMs

Generate machine-readable reports without opening the browser:

hljs language-bash

npx osv-ui -d --json=osv-report.json --markdown=osv-report.md --cyclonedx=sbom.cdx.json --spdx=sbom.spdx.json --no-open

Compare a PR scan against a baseline report and fail on newly introduced high+ findings:

hljs language-bash

npx osv-ui -d --json=current.json --baseline=main-osv-report.json --markdown=osv-pr.md --fail-on=high --no-open

Minimal GitHub Actions flow:

hljs language-yaml

name: osv-ui
on: [pull_request]
jobs:
  scan:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: 20
      - run: npx osv-ui -d --json=current.json --markdown=osv-pr.md --cyclonedx=sbom.cdx.json --fail-on=high --no-open
      - uses: actions/upload-artifact@v4
        if: always()
        with:
          name: osv-ui-report
          path: |
            current.json
            osv-pr.md
            sbom.cdx.json

Send new critical findings to a webhook:

hljs language-bash

npx osv-ui -d --baseline=main-osv-report.json --webhook-url="$SECURITY_WEBHOOK_URL" --webhook-severity=critical --json=current.json

CVE data comes from OSV.dev — a free, open database maintained by Google that aggregates:

🇺🇸 NVD — NIST National Vulnerability Database
🐙 GitHub Advisory Database (GHSA)
🐍 PyPI Advisory Database
📦 npm Advisory Database
🦀 RustSec · Go Vuln DB · OSS-Fuzz · and more

Updated daily. No account. No rate limit. No vendor lock-in.

Works great alongside osv-scanner (Google)

osv-ui and osv-scanner use the same OSV.dev data source. osv-ui adds the visual layer that osv-scanner lacks:

Browser dashboard instead of terminal output
Multi-service sidebar
Dependabot-style upgrade guide with copy commands

vs alternatives

GitLab CI — block deploys on critical CVEs

No Dependabot on GitLab Free? Add this to .gitlab-ci.yml:

hljs language-yaml

audit:
  stage: test
  image: node:20-alpine
  script:
    - npm audit --json > /tmp/audit.json || true
    - |
      node -e "
        const r = require('/tmp/audit.json');
        const crit = Object.values(r.vulnerabilities || {})
          .filter(v => v.severity === 'critical').length;
        if (crit > 0) {
          console.error('BLOCKED: ' + crit + ' critical CVE(s). Run: npx osv-ui');
          process.exit(1);
        }
        console.log('OK: no critical vulnerabilities');
      "
  artifacts:
    paths: [/tmp/audit.json]
    when: always

Requirements

Node.js >= 18
Internet access for OSV.dev queries — or use --offline
npm projects: run npm install first so package-lock.json exists
Python projects: any of the supported manifest files listed above

Roadmap

All contributions are welcome. If you want to work on something, open an issue first so we can coordinate.
