SYNOPSIS

speedo [URL]
speedo [-i|--interactive] [-n|--non-interactive] [-s|--speed-unit UNIT]
speedo [--json] [--format FORMAT] [--compact]
speedo --update-servers
speedo --help
speedo --version

DESCRIPTION

speedo downloads a test file and reports the transfer speed. By default it runs non-interactively against Cloudflare's CDN. With the -i flag, it displays an enhanced interactive menu with 34+ speed test servers organized by region and provider.

The tool supports multiple output formats (human-readable, JSON, CSV) for scripting and automation, and automatically updates its server list from GitHub.

If a URL is provided as an argument, the file is downloaded to the current directory and the speed is reported.

Command-line flags override the config file settings.

OPTIONS

-i, --interactive Show enhanced server selection menu with browse modes (by region, provider, search)

-n, --non-interactive Run quick test (override config)

-s, --speed-unit UNIT Speed unit format (bits-metric, bits-binary, bytes-metric, bytes-binary)

--format FORMAT Output format: json, csv, or human (default)

--json Output JSON format (shorthand for --format json)

--compact Use compact JSON output (no pretty printing)

--update-servers Update remote server list from GitHub

-h, --help Display help text

-V, --version Display version

ARGUMENTS

URL URL to download (saves file to current directory)

CONFIGURATION

Configuration is read from the first file found:

  • ./speedo.toml
  • ./.speedo.toml
  • ~/.speedo.toml

Example Configuration

# Default mode when no flags given (default: false)
interactive = false

# User agent string for requests
user_agent = "Mozilla/5.0"

# Speed unit format for progress display (default: "bytes-metric")
# Options:
#   "bits-metric" or "mbps"  - Megabits per second (Mbps, Gbps) - 1000-based
#   "bits-binary" or "mibps" - Mebibits per second (Mibps, Gibps) - 1024-based
#   "bytes-metric" or "mb/s" - Megabytes per second (MB/s, GB/s) - 1000-based (default)
#   "bytes-binary" or "mib/s" - Mebibytes per second (MiB/s, GiB/s) - 1024-based
speed_unit = "bytes-metric"

# Additional test servers
[[custom_servers]]
name = "My Server"
url = "https://example.com/testfile.bin"

See speedo.toml.example for details.

EXAMPLES

Run a quick speed test (default server):

speedo

Download a specific file:

speedo https://example.com/testfile.zip

Show interactive menu with enhanced browse modes:

speedo -i

Update server list from GitHub:

speedo --update-servers

Force non-interactive mode (override config):

speedo -n

Use bits per second instead of bytes:

speedo --speed-unit bits-metric

Download with custom speed unit:

speedo -s bits-binary https://example.com/file.bin

Output results as JSON:

speedo --json
speedo -n --json --compact | jq '.results.speed.mbps'

Output results as CSV (for logging):

speedo -n --format csv >> speed_tests.csv

OUTPUT

Non-interactive mode prints the transfer summary and speed:

Downloaded 95.37 MiB in 4.69s - 20.33 MB/s  (170.58 Mbps)

When downloading a URL, the saved filename is also printed:

Downloaded 95.37 MiB in 4.69s - 20.33 MB/s  (170.58 Mbps)
Saved: testfile.zip

Interactive mode displays a progress bar during download, then shows:

  • Transfer summary (size and time)
  • HTTP status code
  • Connection time
  • Time to first byte (TTFB)
  • Total transfer time
  • File size
  • Transfer speed

Speed Unit Configuration

You can configure the speed display format in speedo.toml:

  • bits-metric - Mbps, Gbps (megabits, gigabits per second - 1000-based)
  • bits-binary - Mibps, Gibps (mebibits, gibibits per second - 1024-based)
  • bytes-metric - MB/s, GB/s (megabytes, gigabytes per second - 1000-based) - default
  • bytes-binary - MiB/s, GiB/s (mebibytes, gibibytes per second - 1024-based)

  • 🗺️ Region - Browse by continent/region
  • 🏢 Provider - Browse by hosting company
  • 🔍 Search - Filter by location, name, provider

Server Updates

The server list is automatically updated from GitHub and cached locally for 7 days. Force an update with:

speedo --update-servers

Why AWS, GCP, Azure Aren't Included

Major cloud platforms (AWS, Google Cloud, Microsoft Azure) don't provide public HTTP speed test files like infrastructure providers do:

  • Infrastructure providers (Hetzner, Vultr, Linode) offer dedicated speed test servers with standardized 100MB files at known URLs to help customers choose data centers
  • Cloud platforms (AWS, GCP, Azure) expect customers to deploy their own test infrastructure using their services

The included providers represent all major hosting companies that offer public, unauthenticated HTTP speed test downloads. Cloud platforms would require API authentication or custom resource deployment, which is outside the scope of a simple speed test tool.
