---

• Cluster ready. Designed with concurrency and on-demand scalability¹ in mind
• Debuggable. Provides browser screen recordings, extensive logs, and tracing
• Fast. Built for speed and performance on a single grid instance
• W3C Specification compilant. Fully compatible with existing Selenium 4 clients

Install

Below are quick-start tutorials to get you started. For a more detailed introduction visit the dedicated Getting Started guide!

🐳 Docker

To run a basic grid in Docker you can use Docker Compose. Below is a bare-bones example of getting all required components up and running!

# Create prerequisites
docker network create webgrid

# Download compose file
curl -fsSLO webgrid.dev/docker-compose.yml

# Launch the grid
docker-compose up

You can now point your Selenium client to localhost:8080 and browse the API at /api.

☸️ Kube

For deployment to Kubernetes a Helm repository is available. The default values provide a good starting point for basic cluster setups like K3s or microk8s.

# Add the repository
helm repo add webgrid https://webgrid.dev/

# List all available versions
helm search repo --versions --devel webgrid/demo

# Install the chart
helm install example webgrid/demo --version "<pick-a-version-from-the-list>"

# Make it accessible locally for evaluation
kubectl port-forward service/example-webgrid 8080:80

Your grid is now available at localhost:8080.

If you are deploying to a RBAC enabled cluster you might have to tweak some settings. Take a look at the documentation on how to use your own ServiceAccount and PersistentVolumeClaims.

Usage

Once you have your grid up and running there is a couple of things you can do!

🚀 Launch browser instances

Point your selenium client to http://localhost:8080 to create a new browser container/pod and interact with it! You can use all features supported by Selenium.

🔍 Browse the API

The grid provides a GraphQL API at /api with a Playground for you to explore. It exposes all available metadata about sessions, grid health and advanced features like video recordings.

📺 Watch your browsers

You can take a live look at what your browsers are doing by taking the Session ID of a instance and visiting localhost:8080. You can also embed the videos in your existing tools! Head over to the embedding documentation to learn how.

_{Note:
Video recordings are disabled by default in K8s as every cluster has specific requirements for file storage. The storage documentation explains how to enable it.}

Developing

If you want to build the project locally you can use the Makefile. To create Docker images for every component and run them locally run these commands:

# Build docker images
make

# Start components in docker
make install

To start individual components outside of Docker or setup the development environment, see the development environment documentation.
