Fast

Test your internet speed from the command-line, powered by fast.com.

Usage

Run a speed test:

fast

fast measures your download speed first and upload speed second against the nearest Netflix Open Connect servers, then shows the final ping to that server, all inline in your terminal.

Run a full-duplex stress test:

fast --simultaneous

Print the installed version:

fast --version

Installation

Install or update with Go:

go install github.com/AnkanMisra/fast@latest

Or download a binary from the releases.

Update Notifications

fast checks GitHub Releases at most once every 24 hours during interactive runs and lets you know when a newer version is available.

Disable update checks for one run on macOS/Linux:

FAST_NO_UPDATE_NOTIFIER=1 fast

Disable update checks for one run on Windows PowerShell:

$env:FAST_NO_UPDATE_NOTIFIER="1"; fast

Disable update checks for one run on Windows cmd.exe:

set FAST_NO_UPDATE_NOTIFIER=1 && fast

To verify the command without running a speed test, use fast --version:

set FAST_NO_UPDATE_NOTIFIER=1 && fast --version

Releasing

Create and push a semver tag to publish fresh binaries and checksums:

git tag v0.1.0
git push origin v0.1.0
