## What it is
Zalenium is a container-based Selenium Grid that scales dynamically using Docker (and works on Kubernetes), with video recording, live preview, basic auth, and a dashboard. It runs tests in Firefox and Chrome locally via docker-selenium and redirects unsupported capabilities to cloud providers like Sauce Labs or BrowserStack.

## Use cases
- run selenium ui tests in a scalable docker grid
- spin up a disposable selenium grid in seconds
- record videos of browser test sessions
- run cross-browser tests on kubernetes
- route tests to sauce labs or browserstack when local browsers are unavailable
- live preview browser sessions during test runs

## When to choose
- you need an on-demand, scalable Selenium Grid in Docker or Kubernetes
- you want video recording and live preview of test sessions
- you want to combine local docker-selenium nodes with cloud testing providers

## When to avoid
- you need an actively maintained project - Zalenium is discontinued and its features moved to Selenium Grid 4 docker-selenium
- you need browsers other than Chrome or Firefox locally without a cloud provider
- you need a non-Selenium testing setup
