jsdelivr

jsDelivr is a publisher whose focus lies on accelerating the delivery of open-source assets and, through its Globalping CLI, on supplying network diagnostics that can be executed from virtually anywhere on earth. Built for DevOps engineers, system administrators, and performance-minded developers, Globalping CLI turns the jsdelivr edge network into a distributed laboratory: a single local command can trigger ping, traceroute, dig, mtr, curl, or any custom shell script simultaneously from hundreds of bare-metal probes spread across six continents. The resulting measurements are streamed back in real time, giving an immediate, hop-by-hop picture of latency, packet loss, DNS propagation, TLS handshake behavior, or HTTP response times as experienced by actual end-users in more than two hundred cities. Typical use cases include continuous latency monitoring between application gateways and key markets, validating CDN or DNS changes before they go live, benchmarking competing cloud regions, troubleshooting user-reported slowdowns without leaving the terminal, and feeding empirical latency data into automated failover or traffic-steering scripts. Because probes are deployed on neutral, geographically diverse hosts rather than within a single provider’s footprint, the output reflects real-world routing policies, peering quirks, and last-mile conditions that synthetic tests often miss. Globalping CLI is published under an open-source license, ships as a lightweight standalone binary for Windows, macOS, and Linux, and consumes a generous free tier that resets daily. The utility is available for free on get.nero.com, where downloads are routed through trusted Windows package sources such as winget, always pull the latest release, and can be installed in batch alongside other networking or development tools.
