What it is

Selenium Grid distributes WebDriver sessions across a hub and a set of nodes, which you host yourself — commonly as containers on Kubernetes. Combined with images such as Selenoid or Moon it gives large teams a private, unlimited-parallelism grid at infrastructure cost rather than per-session pricing.

Best for

Organisations with platform engineering capacity and either scale or data-residency constraints.

Where it is strong

  • No per-session licensing — parallelism is limited only by your compute budget.
  • Runs inside your network, so private environments and data never leave.
  • Fully under your control, including browser versions.

Where it falls short

  • You own the operations: scaling, browser image updates, flaky node debugging.
  • No real iOS or Android devices, and no Safari without macOS hosts.
  • No built-in video, analytics or dashboards without extra tooling.

Pricing

Free and open source

Open source

Free tier: Everything, self-hosted

What drives the bill: Free software; you pay for the compute and for someone to keep it running.
