## What it is
Selenium is an umbrella project of tools and libraries for automating web browsers, providing the infrastructure for the W3C WebDriver specification. It includes WebDriver language bindings, Selenium Grid for distributed parallel execution, and Selenium IDE for record-and-playback.

## Use cases
- automate browser interactions for testing web applications
- run cross-browser regression test suites
- scrape data from websites that require JavaScript rendering
- distribute and scale browser tests across multiple machines with Selenium Grid
- record and replay browser interactions with Selenium IDE
- automate repetitive web-based administration tasks

## When to choose
- you need cross-browser automation compatible with all major browsers
- you want a W3C-standard WebDriver API with bindings in many languages
- you need to scale tests in parallel across environments with Grid
- you need mature, widely supported browser automation with a large ecosystem

## When to avoid
- you only need fast, lightweight HTTP-level API testing without a real browser
- you want a simpler modern alternative like Playwright for a single language stack
- you need mobile app automation (consider Appium, which builds on WebDriver)
- you need pure static HTML parsing without browser rendering

## Facets
- artifact type: framework
- maturity: stable
- function: testing, e2e-testing, web-scraping, workflow-automation
- domain: testing, web-development, developer-tools
- platform: cross-platform, jvm, python, dotnet, ruby, rust
