Remove and reinstall.
Confirm where labs-speedtest is, delete that install, confirm the command is gone, then run the same installer so you land on v0.1.2. After remove, Get-Command / command -v should not resolve the binary.

Application-layer measurements
Labs Speedtest opens real HTTPS requests and reports the throughput and round-trip time your applications would see, so the numbers reflect the web path rather than a lower-layer probe. A default run also shows your link type (ethernet or wifi), local IP and public IP; share-to-social still uses this shop URL and does not include those addresses.
Built for the terminal
One small binary, scriptable output and sensible defaults. Results open with Labs Speedtest and the running version, and the footer is https://www.myevent-labs.io (clickable in capable terminals). Press h or ? for in-app help.
Stay current
Run labs-speedtest --update, or press u in the running app, to fetch a newer build from the CDN, verify it against SHA256SUMS, then replace the binary and restart. The install one-liners on this page stay the same; they keep putting labs-speedtest on your PATH.
Honest about what it is
It is an HTTPS throughput and round-trip time tool, not a network diagnostic suite. It does not send ICMP echoes and it does not run a traceroute.
| Key or command | What it does |
|---|---|
h or ? | Open in-app help while Labs Speedtest is running. |
u | Self-update from the CDN, verify SHA256SUMS, replace the binary and restart. |
labs-speedtest --update | The same self-update from the command line, without the interactive session. |

Prefer to install by hand? Download the archive for your platform, verify it against SHA256SUMS, then unpack and run it yourself. The one-line installer at the top of the page does this for you.
Verify your download against SHA256SUMS. Compute the SHA-256 of the file you downloaded and confirm it matches the line for that file name.
Once downloaded, unpack the archive and run labs-speedtest from your terminal. On Windows, unzip the .zip and run labs-speedtest.exe, or add it to your PATH. Builds are not code-signed, so Windows SmartScreen and macOS Gatekeeper may ask you to confirm the first launch.

How do I install and run it?
Open your terminal and paste the one-line install script for your system: on macOS or Linux run "curl -fsSL https://releases.myevent-labs.io/labs-speedtest/install.sh | sh", and on Windows PowerShell run "irm https://releases.myevent-labs.io/labs-speedtest/install.ps1 | iex". It installs everything and puts labs-speedtest on your PATH, so you then just type labs-speedtest to run it. Prefer to install by hand? Download the build for your platform from the downloads on this page, unpack the archive, and run labs-speedtest (on Windows, unzip the .zip and run labs-speedtest.exe). There is no installer to click through and no licence key.
How do I check the download is genuine?
Every release publishes a SHA256SUMS manifest next to the downloads. After downloading, compute the SHA-256 of your file and confirm it matches the line for that file name - on macOS or Linux with "shasum -a 256 <file>", and on Windows with "certutil -hashfile <file> SHA256". Only the official archives listed on this page are supported.
How do I update it?
From a terminal run "labs-speedtest --update", or press u while the app is running. It checks the CDN for a newer build, verifies SHA256SUMS, replaces the binary and restarts. The install one-liners on this page are unchanged - they still install labs-speedtest and put it on your PATH.
How do I remove it and install again?
Confirm the current binary, delete the install location, confirm the command is gone, then run the same one-liner. On Windows PowerShell prefer Remove-Item "$env:LOCALAPPDATA\Programs\labs-speedtest" -Recurse -Force (same folder as C:\Users\Username\AppData\Local\Programs\labs-speedtest). Sequence: (Get-Command labs-speedtest).Source, then that Remove-Item, then Get-Command labs-speedtest, then irm https://releases.myevent-labs.io/labs-speedtest/install.ps1 | iex. On macOS or Linux the default install is ~/.local/bin: command -v labs-speedtest, then rm -f "$HOME/.local/bin/labs-speedtest" "$HOME/.local/bin/mls", then command -v labs-speedtest, then curl -fsSL https://releases.myevent-labs.io/labs-speedtest/install.sh | sh.
How do I get help in the app?
Press h or ? while Labs Speedtest is running for in-app help. You can also run labs-speedtest --help for the full flag list.
What do the results include?
A default run reports download, upload and HTTPS round-trip time, then Link (ethernet or wifi), Local IP and Public IP. The header shows Labs Speedtest and the running version; the footer is https://www.myevent-labs.io. Sharing still uses this shop URL and does not include IP addresses.
Is this ping or traceroute?
No. Labs Speedtest measures HTTPS application-layer throughput and round-trip time. It does not send ICMP echo requests and it does not trace the route between hops.
What does it cost?
It is free. There is no licence key and nothing to buy. The prebuilt downloads are free on this page; the source repository is currently private, but you do not need it to download and run the tool.
