Installation (Platform)

How to use the StormForge CLI with the Platform Performance Testing environment.

StormForge provides a command line tool called stormforge that can be used to interact with the Performance Testing application for easy local development of test cases and integration into CI/CD pipelines. It can also be used to interact with Optimize Live and Optimize Pro. This guide shows how to install the stormforge CLI and some common usage examples.

Installing the StormForge Command Line Interface

Linux Binary Download:

Amd64 | Arm64

Linux install command:

# Automatically selects either AMD64 or ARM64 architecture, downloads
# the appropriate binary, then moves it to a location in PATH
{ [ "$(uname -sm)" = "Linux x86_64"  ] && curl -L | tar -xz; } ||
{ [ "$(uname -sm)" = "Linux aarch64" ] && curl -L | tar -xz; } &&
sudo mv stormforge /usr/local/bin/

Windows Binary Download:

Amd64 | Arm64

PowerShell install command:

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
If ($env:PROCESSOR_ARCHITECTURE -eq "AMD64") { Invoke-WebRequest -Uri "" -Outfile "" }
If ($env:PROCESSOR_ARCHITECTURE -eq "ARM64") { Invoke-WebRequest -Uri "" -Outfile "" }
Expand-Archive "" "." -WarningVariable $w; if ($w.Count -eq 0) { Remove-Item "" } 

Then, move stormforge.exe to a folder defined in your Windows PATH environment variable.

macOS Binary Download:

Amd64 | Arm64

macOS install command:

# Automatically selects either AMD64 or ARM64 architecture, downloads
# the appropriate binary, then moves it to a location in PATH
{ [ "$(uname -sm)" = "Darwin x86_64" ] && curl -L | tar -xz; } ||
{ [ "$(uname -sm)" = "Darwin arm64"  ] && curl -L | tar -xz; } &&
sudo mv stormforge /usr/local/bin/


brew install thestormforge/tap/stormforge

We provide a container image at (for linux/amd64 and linux/arm64):

docker pull

We recommend setting the STORMFORGE_TOKEN environment variable (from auth create -o token) if you want to use the container image directly.


API access is managed via API tokens. Once registered at, you can either login with your user account or you can register a new authorization token (or machine to machine client) to use the CLI in CI/CD pipelines or other automation scenarios.

User Account

You can login to your StormForge user account via a web-based form:

stormforge login

Alternatively, you can get a one-time use code to enter into a browser from another device:

stormforge login --url

At anytime you can check to see that you can communicate with the API:

stormforge ping

Authorization Tokens

You can also create an authorization token to use in automated workflows. See our GitHub or GitLab guides for an example. To create a token, run stormforge auth create -o token on your own machine after logging in (see above):

$ stormforge auth create 'github-action'

You can now copy the generated output and pass it as an environment variable STORMFORGE_TOKEN to the stormforge binary and it will be authenticated.

Creating and updating your Test Case

You can use the stormforge create test-case subcommand to create a test case in your organization from a local file. This command performance an upsert operation, so if you specify a test case name that already exists, it will be updated.

stormforge create test-case sandbox --from-file cases/blackfriday.js

For more options and information about creating test cases with the stormforge CLI, see the online help

stormforge create test-case --help

Debugging a Test Case

Launching a Validation Run allows you to ignore the defined arrival phases and run a single user for each defined session. This allows validation that the defined session flow works as expected. Note that randomness is still a factor and random branching may lead to slightly different results between validation.

To launch a Validation Run, you can use the following command:

stormforge create test-run --test-case sandbox --from-file cases/blackfriday.js --validate

The command above uses the following flags:

  • --test-case - specifies the test case that should be used for this test run
  • --from-file - Update the test case file as part of the launch command - this saves a separate update command invocation
  • --validate - Enables the session validation mode with exactly one user per session and checks for any requests errors after the test run finished

For more tips and tricks on debugging test cases, see our dedicated Debugging page.

Running your Test Case

To finally run a test case, you can drop all the additional flags and just use the stormforge create test-run --test-case <test-case> command.

stormforge create test-run --test-case sandbox

Within a CI/CD environment we recommend using --label, --notes or --title to add context to your Test Launch, e.g. the job id or URL, git commit hash or deployed version of the target site. Adding --watch ensure your CI/CD job blocks until the test run finished. Finally --from-file updates the test case as part of the launch command to ensure you are launching the exact version that is seen by your CI/CD system.

stormforge create test-run --test-case sandbox --watch \
  --title="CI/CD Test Run ${JOB_ID}" \
  --notes="git: $(git describe --tags)" \
  --label="git-sha=$(git rev-parse HEAD)" \
  --label="target=staging" \
