Speedtest-cli is a command-line utility designed to measure internet upload and download throughput by connecting to remote servers. It functions as a diagnostic tool for evaluating connection quality and verifying network performance against service provider claims.
The utility identifies testing endpoints by calculating the physical distance between the client and available servers, ensuring measurements are based on responsive nodes. It manages the testing lifecycle by coordinating with remote services to fetch server lists and register results, which can be exported into machine-readable formats like JSON or CSV for integration with external monitoring systems.
Beyond basic throughput measurement, the tool supports network troubleshooting by allowing users to filter testing locations based on specific criteria or proximity. It also provides functionality for generating unique web links that display visual summaries of completed tests, facilitating the reporting and comparison of connection performance.
