A Node.js CLI tool that measures internet download and upload speeds using fast.com. It supports JSON output, verbose latency and location info, and single-line output for scripting.

Use cases

• check my internet download speed from the terminal
• measure upload speed via fast.com in a script
• get internet speed test results as JSON for automation
• check latency and bufferbloat from the command line
• log bandwidth measurements to a file over time
• quickly test connection speed without opening a browser

When to choose

• you want fast.com-based speed tests from the terminal or in scripts
• you need machine-readable JSON speed results for monitoring or automation
• you prefer a lightweight CLI over browser-based speed tests

When to avoid

• you need speed tests against speedtest.net or other providers
• you cannot install Puppeteer/Chromium dependencies in your environment
• you need a GUI or continuous bandwidth monitoring dashboard
