Selenium Grid vs BrowserStack

Free and open source

From $29 per month (Live manual testing, single user)

Free software; you pay for the compute and for someone to keep it running.

Automate plans are priced per parallel session and are the real cost — expect roughly $150-$250 per parallel session per month at small scale.

Everything, self-hosted

Limited free trial minutes; free for open-source projects on application.

• 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.

• The broadest device and browser matrix available, including older versions and new devices quickly.
• Works with essentially every automation framework, so migration is low-risk.
• Manual live testing on real devices is excellent for reproducing customer reports.

• 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.

• Parallel-session pricing gets expensive fast, and idle capacity is still billed.
• Remote sessions are slower than local execution, lengthening feedback loops.
• The product surface has sprawled; you will be sold several adjacent modules.

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

Teams needing a wide real-device matrix without maintaining a lab.
