Utility Matrix is a free collection of browser-based tools for DevSecOps engineers, security practitioners, and platform teams.
Every calculator on Utility Matrix runs entirely in your browser — no calculation inputs are sent to our servers. Some site features, such as usage analytics and shared result links, may use network requests. Our tools cover security validation (CVE, CWE, MITRE ATT&CK), infrastructure (CIDR, SSL cert expiry), reliability engineering (SLO burn rate), and developer workflows (JWT decoding, dependency CVE scanning, Dockerfile linting, Kubernetes manifest validation).
Tools should be fast, offline-capable, and privacy-preserving. We do not require accounts, logins, or any data submission to use any tool. Results are computed locally using standard browser APIs.
Utility Matrix is free to use. Some tool pages may feature contextual affiliate links to commercial services that extend what you can do with the tool's output. These links are clearly labelled and use rel="sponsored nofollow noopener noreferrer" attributes. Affiliate relationships do not affect tool accuracy or editorial coverage.
