Selenium Grid Docker Images Are Now Mirrored to GHCR

Sat, 04 Apr 2026 00:00:00 +0000

The request started with a simple question in issue #2939: can we publish Selenium Grid Docker images to GitHub Container Registry as well as Docker Hub?

The answer is now yes.

Official Selenium Grid Docker images are now available from GitHub Container Registry (GHCR) under:

ghcr.io/seleniumhq

This is a mirror, not a replacement. Docker Hub remains available, and existing users do not need to change anything. But if your environment prefers GHCR, blocks Docker Hub, or simply wants another official source for the same images, you now have one.

HtmlUnit Remote: Acquiring Remote HtmlUnitDriver Session in Selenium 4 Grid

HTMLUNIT REMOTE

The HtmlUnit Remote project implements a W3C WebDriver protocol wrapper for HtmlUnitDriver, which enables Selenium 4 Grid to supply remote sessions of this headless browser.

Background

To eliminate behavioral differences between local and remote configurations, the Selenium Foundation framework always acquires browser sessions from a Grid instance, managing its own local grid instance when not configured to use an existing grid. Selenium 3 Grid could be configured to supply HtmlUnitDriver sessions, supported by special-case handling within the Node server itself. This handling was not carried over into Selenium 4 Grid, which was completely re-engineered with new architecture and vastly expanded capabilities.
