speedtest-cli is a Python-based command-line tool for testing internet bandwidth using Speedtest.net infrastructure. It measures download speed, upload speed, and ping latency against Ookla's worldwide server network.
The tool supports multiple output modes including simple (single-line metrics), JSON, and CSV for scripting and monitoring integration. A share option generates a URL to an image of the results on Speedtest.net. Specific test servers can be selected by ID, and individual tests (download or upload) can be skipped to speed up partial measurements.
The tool uses HTTPS connections by default with the --secure flag and can show results in bytes per second instead of bits. It is community-maintained and distinct from Ookla's official speedtest CLI binary.
