Next generation CLI for testing internet bandwidth using speedtest.net

Rebuilt for modern Python 3.12+

Getting started

Installation

PyPI

You can install speedtest-cli-ng from PyPI using either standard Python packaging tools or uv.

Using pip

If you have pip only. You can also use pipx to run the tool without installing.

Using uv

You can run the tool instantly without explicitly managing environments:

uvx speedtest-cli-ng

or install it globally:

uv tool install speedtest-cli-ng

Usage

To view the available options, run the help command:

speedtest-cli --help

usage: speedtest-cli [-h] [-l] [-s SERVER] [--no-download] [--no-upload]
                     [-t THREADS | --single] [--share] [--bytes] [--json]
                     [--debug] [--version]

Next generation CLI for testing internet bandwidth using speedtest.net.

options:
  -h, --help            show this help message and exit

Core Options:
  -l, --list            Show available speedtest.net servers sorted by distance. (default: False)
  -s SERVER, --server SERVER
                        Specify a server id to test against. (default: None)

Transfer Modifiers:
  --no-download         Do not perform the download test. (default: False)
  --no-upload           Do not perform the upload test. (default: False)
  -t THREADS, --threads THREADS
                        Set the number of concurrent connections instead of using downloaded config. (default: None)
  --single              Use one concurrent connection. Simulates a typical file transfer. (default: False)

Output Options:
  --share               Generate and provide a URL to the speedtest.net share results image. (default: False)
  --bytes               Display values in bytes instead of bits. Does not affect image generation or JSON output. (default: ('bit', 1))
  --json                Suppress verbose output, only show basic information in JSON format. Speeds listed in bit/s. (default: False)

Miscellaneous Options:
  --debug               Show verbose debugging output. (default: False)
  --version             show program's version number and exit

Development

Requirements

• Python 3.12+
• uv 0.11+

Setup project

This will install project's dependencies. Keep in mind that there are no runtime dependencies in production.

uv sync

Basic workflow

# Run format
uv run ruff format --check .

# Run lint
uv run ruff check .

# Run typecheck
uv run pyright

# Run tests
uv run pytest

Building

Build both sdist and wheel package:

uv run build

The output will be in the dist/ directory.

Acknowledgments

This project is a heavily refactored and modernized fork of the original speedtest-cli created by Matt Martz. While the codebase has been completely rewritten to support modern Python standards, concurrent thread pools, and memory-safe streaming, it was built upon the foundational concepts of the original tool.
