cloudflare-speed-cli

cloudflare-speed-cli is a Rust-based command-line internet speed testing tool that interfaces with Cloudflare’s public speed test endpoints, letting users measure download and upload throughput, latency, and more from a terminal. It presents results in an interactive text-user-interface (TUI) that charts real-time metrics as tests run, making it easy to visually inspect performance trends without leaving the console. The tool also stores historical test results and can export measured data as structured JSON for scripting, logging, or integration with automation tools. Users can bind tests to specific network interfaces or source IPs, making it flexible for complex networking environments or servers with multiple network paths. In addition to TUI mode, it supports headless text or JSON output for pipelines and monitoring systems.
