Selenium Grid Hosting on Offshore VPS

Selenium Grid splits into a hub (router) and nodes (workers). The hub receives test requests and dispatches them to nodes capable of running the requested browser. A typical setup is one hub VPS plus several node VPS each running Chromium, Firefox, and Edge containers. Our recommendation: 4GB hub plus three 8GB nodes (one per browser) for a starter setup, scaling up as your test suite grows.

Docker images from the selenium project (selenium/hub, selenium/node-chrome, selenium/node-firefox, selenium/node-edge) install in minutes. Our VPS comes with Docker and Docker Compose preinstalled - one docker-compose up command brings the whole grid online. Configuration is via environment variables (SE_HUB_HOST, SE_NODE_MAX_SESSIONS) - documented thoroughly in the Selenium project docs.

Selenium 4 supports Chromium, Firefox, Edge, and Safari (via WebKit on Linux). Each browser runs in its own Docker container so you can mix and match - 4 Chromium nodes for parallel Chrome tests, 1 Firefox node for cross-browser checks, 1 Edge node for Microsoft-specific bugs. Our VPS handles all three engines simultaneously since we preinstall all required system libraries.

For mobile testing Appium runs on top of Selenium Grid using Android emulator nodes or real device farms. Android emulators are heavy - 8 to 16GB RAM per node is realistic. Our 32GB VPS handles 2 to 3 parallel Android emulators. For iOS testing macOS is required, so most teams pair an AnubizHost Selenium hub with a self-hosted Mac mini at the office - both communicating over a WireGuard tunnel.

Commercial test grids (BrowserStack, Sauce Labs, LambdaTest) charge per parallel session, with enterprise tiers running thousands of dollars per month. Self-hosting on AnubizHost VPS costs roughly $80 per month for a hub plus 3-node grid that handles a serious enterprise test suite. Break-even versus BrowserStack happens in roughly 2 weeks for most teams - everything after is pure savings.

Crypto billing means your QA infrastructure subscription is paid in Bitcoin, Monero, USDT, or Ethereum. No corporate purchase order needed for low-tier plans. Offshore datacenters in Iceland, Romania, or Finland keep your test traces and screenshots under privacy-friendly law. We do not log your test artifacts. Setup from crypto confirmation to working Selenium Grid is typically 30 minutes including initial Docker image pull.
