Selenium

name: Selenium
description: 'Selenium is the open-source browser automation project behind the W3C WebDriver and WebDriver BiDi standards.
  It drives real browsers through a vendor-neutral, standardised HTTP wire protocol that the browser vendors implement themselves,
  with official language bindings for Java, Python, C#, Ruby and JavaScript, all released in lockstep. The suite covers WebDriver
  (the browser-control protocol), Selenium Grid (distributed, parallel execution across machines and platforms), Selenium
  Manager (a Rust CLI that resolves and downloads matching browser drivers automatically) and Selenium IDE (record and playback).
  Selenium is self-hosted software rather than a service: there is no vendor-operated API host, no account and no pricing
  — the remote end runs on infrastructure the consumer owns, at a documented default of http://localhost:4444, under Apache-2.0
  and the stewardship of the Software Freedom Conservancy.'

x-base-url-note: 'apis.yml previously carried baseURL https://www.selenium.dev on every API entry. That is the documentation
  host, not an API host: https://www.selenium.dev/status and https://www.selenium.dev/graphql both returned 404 with the site''s
  Hugo 404 HTML on 2026-08-26, and repair-api-bases.py returns the verdict `no-usable-base` for this provider. Selenium is
  self-hosted software — the WebDriver remote end and Selenium Grid run on infrastructure the consumer owns — and the project
  documents the default base as http://localhost:4444 ("Default URL for all the above modes is http://localhost:4444", https://www.selenium.dev/documentation/grid/advanced_features/endpoints/).
  Every baseURL has been set to that documented default, which also matches the servers[] blocks already present in openapi/.
  A localhost base here is the correct measurement, not a placeholder.'
