Quick Start
This guide walks through installing Speedscale into a new environment. After completing these steps the Speedscale Operator will be installed in your cluster and you should continue on to the tutorial to record, replay and view results for a demo application.
Speedscale is tested with apps hosted on the local desktop all the way up to high scale enterprise Kubernetes clusters. If this is your first time working with Speedscale, it's easiest to just run on your local desktop and record traffic from a local process. Keep in mind that it is very common to record traffic in one environment (like a production Kubernetes cluster) and replay it somewhere else (like a local mock server).
This guide will walk you through the following steps:
- Retrieve your API Key
- Install CLI (recommended)
- Install Operator (if required)
- Verify Installation
- Capture and replay traffic against a demo app
Retrieve your API Key
You will need to get your personal API key from your Profile Page. Copy the API key and paste when prompted.

Install CLI
If you are running Speedscale on a local desktop or in Docker Desktop, the CLI is required. For all other users it is highly recommended because it allows programmatic interaction with Speedscale cloud.
- Mac/Linux
- Windows
Start by installing the Speedscale CLI-based API (speedctl
) via Homebrew:
brew install speedscale/tap/speedctl
Or via the install script:
sh -c "$(curl -Lfs https://downloads.speedscale.com/speedctl/install)"
Open PowerShell and create a Speedscale directory.
mkdir -f $env:userprofile\.speedscale
Download speedctl
into the Speedscale directory.
curl.exe -L "https://downloads.speedscale.com/speedctl/speedctl.exe" -o $env:userprofile\.speedscale\speedctl.exe
If this is your first time using speedctl
you may need to add the Speedscale
directory to your Path environment variable so it is accessible without knowing
the full path.
To add the Speedscale directory to your path, right click on the Windows button and click System.
Click Advanced system settings on the right.
Click Environment Variables.
Under System variables select Path and click Edit.
Create a New entry in the list with the Speedscale directory. If you are unsure of the exact path run this command from PowerShell.
echo $env:userprofile\.speedscale
Click OK and restart PowerShell.
Run the following command. You'll need the API Key copied from the above section.
speedctl init
Install Speedscale
If you are running Speedscale on your local desktop, you should continue directly to the tutorial.
If you are using a common Kubernetes distribution (EKS, GKE, minikube, etc) then you can install using these instructions. If you are not running in Kubernetes, or are running with a more specialized enterprise distribution please select environment-specific instructions in this section.
- Helm
- CLI
- CLI (Windows)
- GitOps
Make sure you have Helm 3 installed. Then,
helm install speedscale-operator speedscale/speedscale-operator \
-n speedscale \
--create-namespace \
--set apiKey=<YOUR-SPEEDSCALE-API-KEY> \
--set clusterName=<YOUR-CLUSTER-NAME>
Navigate to the Helm repository for all configuration options available for the Helm chart.
Run speedctl install
, choose "Kubernetes" and follow the prompts.
The install wizard will walk you through installing the Speedscale Kubernetes Operator and adding the Speedscale Sidecar to your deployment.
(Optional) Adding Image Pull Secrets
If you need custom image pull secrets (for example, if you're re-hosting
Speedscale images in a dedicated registry), you may provide one or more secret
names with the --imgpullsecrets
argument, and the secrets will be attached to
the service account.
speedctl install --imgpullsecrets my-secret1,my-secret2p
Open PowerShell and create a Speedscale directory.
mkdir -f $env:userprofile\.speedscale
Download speedctl
into the Speedscale directory.
curl.exe -L "https://downloads.speedscale.com/speedctl/speedctl.exe" -o $env:userprofile\.speedscale\speedctl.exe
If this is your first time using speedctl
you may need to add the Speedscale
directory to your Path environment variable so it is accessible without knowing
the full path.
To add the Speedscale directory to your path, right click on the Windows button and click System.
Click Advanced system settings on the right.
Click Environment Variables.
Under System variables select Path and click Edit.
Create a New entry in the list with the Speedscale directory. If you are unsure of the exact path run this command from PowerShell.
echo $env:userprofile\.speedscale
Click OK and restart PowerShell.
If using Kubernetes run speedctl install
, choose "Kubernetes" and follow the prompts.
The install wizard
will walk you through installing the
Speedscale Kubernetes Operator
and adding the Speedscale Sidecar to your deployment.
Installing via helm install
is preferred as different GitOps engines treat Helm charts differently and Helm guarantees an order of operations during the install.
You can generate manifests either via Helm or our CLI.
helm template speedscale-operator speedscale/speedscale-operator \
-n speedscale \
--create-namespace \
--set apiKey=<YOUR-SPEEDSCALE-API-KEY> \
--set clusterName=<YOUR-CLUSTER-NAME> > ./manifests
or
speedctl deploy operator -e $(kubectl config current-context) --dir
Verify Installation
Make sure the operator pods are running properly:
kubectl -n speedscale get pods
Note: The Operator will start at least 2 pods (the operator itself and the Speedscale Forwarder) after it starts. On your cluster the ids of the pods will be different.
NAME READY STATUS RESTARTS AGE
speedscale-forwarder-xxxxxxxxxx-xxxxx 1/1 Running 0 5s
speedscale-operator-xxxxxxxxxx-xxxxx 1/1 Running 0 15s
If you have any issues installing, check out the troubleshooting guide or contact support on slack
Next Steps
At this point Speedscale is present in your cluster and you are now ready to target workloads for record and playback. If this is your first installation please continue using our multi-platform tutorial for a full walkthrough.
If you're already an expert you can click the Add Service
button in the UI to automatically add sidecars or install them manually.
