Selenium Grid vs LambdaTest

Free and open source

From $15 per month (entry live plan)

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

Typically the cheapest of the three major clouds per parallel session, with an actually usable free tier.

Everything, self-hosted

Free plan with limited monthly minutes for manual and automated testing.

• 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.

• Best price-to-capability ratio among the major device clouds.
• HyperExecute meaningfully reduces wall-clock time on large suites.
• A free tier you can actually evaluate with.

• 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.

• Support quality is reported as more variable than the incumbents.
• Newest devices sometimes arrive later than on BrowserStack.
• Rapid feature expansion means some modules feel less polished.

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