Badge Embed Guide
Add real-time version health, EOL countdowns, and CVE badges to your README, docs, or website. Every badge auto-updates — zero maintenance.
Quick Start
1. Pick your product from the badge index (300+ supported)
2. Copy the snippet and swap in your product slug
3. Paste into your README — done


Badge Types
Health
Overall health grade (A–F) combining freshness, EOL status, and security data into one score.
/badge/health/{product}.svg
/badge/health/{product}/{version}.svg
Target a specific version:
EOL Countdown
Days remaining until a version reaches end-of-life, or flags it as already EOL. Pin this next to your minimum supported version.
/badge/eol/{product}/{version}.svg
Freshness
Shows whether a version is up to date, slightly behind, outdated, or critically outdated relative to the latest release.
/badge/v/{product}/{version}.svg
CVE
Known CVE count by severity. Currently available for Kubernetes — more products coming soon.
/badge/cve/{product}/{version}.svg
Cloud Provider
Shows K8s version support on EKS, GKE, or AKS with patch details.
/badge/cloud/{provider}/{version}.svg

300+ Products
Works with anything on endoflife.date — Python, Node.js, Go, Rust, Ruby, PHP, Java, .NET, Docker, Kubernetes, PostgreSQL, MySQL, Redis, Terraform, and hundreds more. Just use the product slug in the URL.
ReleaseRun vs Shields.io
Use them together. Shields.io handles CI status and coverage. We handle what they can't:
- ✅ Version health grades (A–F)
- ✅ EOL countdowns with days remaining
- ✅ CVE severity counts per version
- ✅ Cloud provider K8s compatibility
- ✅ Version freshness scoring
Badges are real-time SVGs. Data from endoflife.date (300+ products) plus ReleaseRun's CVE and cloud databases. Cached 5 min with stale-while-revalidate — your README will never show a broken image.
