This repository provides Docker images and Kubernetes Helm charts for deploying Selenium Grid, the industry-standard browser automation framework. It covers all major browser backends (Chrome, Firefox, Edge, Chromium) and supports multiple deployment modes: standalone single-container, hub-and-node, fully distributed grid, and dynamic grid with Docker-in-Docker or Kubernetes backends. The architecture follows a microservice pattern where each Grid component (Router, Distributor, Session Queue, Nodes, etc.) runs in its own container, orchestrated by supervisord. Beyond core Grid images, the repo includes a comprehensive monitoring stack with a Go-based Prometheus exporter that scrapes the Grid GraphQL endpoint, pre-built Grafana dashboards, and a KEDA external scaler for Kubernetes native autoscaling. Video recording and upload services are provided as sidecar containers, with both event-driven (ZeroMQ) and polling-based implementations. The CI/CD pipeline is extensive, with GitHub Actions workflows for building multi-architecture images (amd64/arm64), running integration tests, scanning for vulnerabilities, and publishing to Docker Hub and GHCR. The codebase is well-tested with unit tests for Go components, Python integration tests for autoscaling, and Java/Playwright browser tests. Despite its complexity, the repository demonstrates solid engineering practices with clear separation of concerns, reusable shell libraries, and automated dependency management via Renovate and Dependabot.
Sitespeed.io is a mature, open-source web performance testing and monitoring tool that drives real browsers (Chrome, Firefox, Edge, Safari, including mobile) to collect a comprehensive set of performance metrics. It measures Core Web Vitals (LCP, INP, CLS, TTFB, FCP), visual metrics (Speed Index, filmstrip), HAR waterfalls, CPU long tasks, third-party requests, accessibility violations (via axe-core), and sustainability metrics (CO₂ estimates). The tool is used for one-off audits, CI/CD performance budgets, and continuous production monitoring, with results output as rich HTML reports, JSON, JUnit/TAP, and time-series data sent to Graphite/InfluxDB/Grafana. The architecture is plugin-based: a core message queue orchestrates a pipeline of plugins (setup → url → summarize → render). Built-in plugins handle browser testing (via Browsertime), HAR analysis (PageXray), best-practice advice (Coach), accessibility, sustainability, statistical comparison (Mann-Whitney U), performance budgets, and result storage (S3, GCS, SCP, Rsync). The CLI is built with yargs and supports ~600 options organized into topical modules. The tool is primarily delivered as a Docker image (multi-arch amd64/arm64) and an npm package. Key entry points are `bin/sitespeed.js` (CLI), `lib/sitespeed.js` (programmatic API), and `docker/scripts/start.sh` (Docker entrypoint). External dependencies include Browsertime, Coach Core, PageXray, axe-core, and the third-party-web dataset. The project has extensive CI/CD (GitHub Actions), a documentation site built with Eleventy, and a release workflow that publishes npm packages and Docker images with Sigstore signatures and SBOMs.
Laravel Dusk is a browser automation and testing library for Laravel applications. It provides a fluent, expressive API for interacting with web pages via ChromeDriver or Selenium WebDriver, enabling end-to-end testing without requiring JDK or Selenium server. The library integrates deeply with Laravel's testing infrastructure (PHPUnit/Pest), offering a TestCase base class, console commands for installation and ChromeDriver management, and a rich set of assertions and interactions (clicking, typing, waiting, screenshots, Vue component inspection). It is architecturally a library that wraps the php-webdriver package, adding Laravel-specific conveniences such as environment management, cookie encryption, authentication helpers, and page/component abstractions. The codebase is well-structured with traits for separation of concerns, macroable support for extensibility, and comprehensive unit and browser test coverage.
HeadlessX is a self-hosted web scraping and browser automation platform with anti-detection capabilities. It provides a Next.js 16 dashboard, an Express 5 API with Prisma/PostgreSQL, a BullMQ queue worker, and a published CLI. The core value proposition is anti-detection scraping via the headfox-js package (Camoufox-compatible Firefox bundles), fingerprint generation, CAPTCHA solving, and LLM-friendly markdown output. The system supports multiple operators: website scraping/crawling/mapping, Google AI Search, Tavily search, Exa search, and YouTube extraction. It includes sidecar services for HTML-to-Markdown (Go) and YouTube extraction (Python FastAPI). The architecture is a monorepo with Nx orchestration, Docker Compose deployment, and an MCP endpoint for AI assistant integration. External dependencies include Redis, Postgres, Playwright, MaxMind GeoIP, and external APIs (Tavily, Exa, Google). The codebase is well-structured with clear separation of concerns, modern TypeScript, and reusable patterns in both frontend and backend.
This repository is a Karma plugin that enables running unit tests on Sauce Labs cloud browsers. It provides a launcher to set up browser sessions via WebDriverIO and Sauce Connect tunneling, and a reporter to send test results back to Sauce Labs for display in their dashboard. The architecture follows Karma's plugin interface with separate modules for launcher, reporter, tunnel management, and configuration processing. The code handles both legacy JSONWP and modern W3C WebDriver protocols, manages session heartbeats, and processes test annotations for Sauce Labs reporting. External dependencies include WebdriverIO, Sauce Labs Node.js client, and global-agent for proxy support.
