Introduction

Docker Selenium provides ready-to-run container images for Selenium Grid. Images exist for standalone browsers (Chrome, Edge, Firefox and Chromium), Grid hub and nodes, and every component of a fully distributed Grid (Router, Distributor, Event Bus, Session Map and Session Queue). Images are published to Docker Hub.

The README lists a single standalone image with all browsers, experimental multi-architecture images for amd64 and aarch64, video recording, VNC and noVNC access to watch sessions, and a dynamic grid that launches a new container per session.

For Kubernetes, the project’s Helm chart creates a Selenium Grid and can autoscale browser nodes with KEDA based on the session queue. Releases track Selenium versions closely (for example 4.52.0-20261101).

In the quality loop it is the easiest path to self-hosted browser infrastructure for end-to-end tests.

The source code is at SeleniumHQ/docker-selenium on GitHub under the Apache-2.0 licence, with about 8,700 stars; the most recent commit was on 5 November 2026.

Features

1. Browser images: Chrome, Edge, Firefox and Chromium images.
2. All Grid roles: Hub, node and distributed component images.
3. Video and VNC: Record or watch sessions.
4. Dynamic grid: One container per session.
5. Helm chart: Grid on Kubernetes with KEDA autoscaling.
6. Multi-arch: Images for ARM as well as x86.

Pros

1. Fast setup: A working Grid in one docker run or docker compose up.
2. Free to use: Open source under the Apache-2.0 licence, so the core tool costs nothing to use.
3. Actively maintained: The repository had commits as recent as 5 November 2026.
4. Community: About 8,700 GitHub stars.

Cons

1. Resource hungry: Browsers need memory and shared memory (--shm-size).
2. Ops still required: Kubernetes autoscaling needs tuning.

Usage and Links (Example)

docker run -d -p 4444:4444 -p 7900:7900 --shm-size="2g" selenium/standalone-firefox:latest

Open http://localhost:7900 to watch the session via noVNC.
