How Scoring Works
Freshness (35%)
Is the latest version recent? How far behind is the current release cycle? Technologies with active release cadences score higher.
Security (35%)
Known CVEs, unfixed vulnerabilities, and time since last security patch. A critical unfixed CVE caps your grade at D.
EOL Status (30%)
Is the version still supported? How long until end-of-life? Anything past EOL for 1+ year forces an F.
Grade Scale
Excellent — current, secure, well-supported
Good — minor updates available
Fair — approaching EOL or overdue patches
Poor — security issues or near EOL
Critical — past EOL or unpatched CVEs
Failing — unmaintained, dangerous in production
FAQ
Is my data sent anywhere?
No. Everything runs in your browser. We fetch badge images from img.releaserun.com (which are public URLs), but your stack selection never leaves your device.
How are health grades calculated?
Each technology gets a grade from A to F based on three factors: version freshness (35%), known CVEs (35%), and end-of-life status (30%). The overall stack grade is the weighted average. Data comes from endoflife.date, CVE databases, and release tracking.
Can I embed the scorecard in my docs?
Yes! Use the "Copy as Markdown" button to get badge embed codes for each technology. Or use the Badge Builder for individual badge customization.
What technologies are supported?
We track 300+ technologies via endoflife.date and our own release monitoring. The scorecard shows the most popular ones, but our Badge Builder supports the full catalogue.
