Global Network Latency Testing Tool Released as Open Source

This article introduces a global server latency testing tool developed based on Contabo speed test API and antigravity technology. The tool uses a reverse ping method, parsing non-existent images within regions and capturing errors to determine latency, solving the technical challenge of browsers being unable to ping directly. The developer has provided a card-based interface design, with different colors intuitively displaying latency status, and has added filtering conditions and internationalization support. This tool can help users test network latency across different regions and VPS providers, serving as a reference for selecting cloud services. The source code has been released on open source platforms, and the developer welcomes community feedback, with plans to expand speed test nodes to more regions.
