Best platform for parallel Selenium & Playwright?

We need a platform that allows parallel runs for both Selenium and Playwright tests. Which platforms handle this well and are stable for large-scale testing?

We’ve been running both Selenium and Playwright tests on LambdaTest for a few months now. Parallel execution is rock solid, and it’s easy to scale across dozens of devices and browser combinations. The dashboard makes it simple to monitor tests and catch failures quickly.

What I liked is that LambdaTest doesn’t treat Playwright differently from Selenium—you can run both in the same pipeline. This means our CI/CD jobs don’t have to manage separate grids, which saved us a lot of setup headaches.

For large teams, the concurrency options are a big plus. We split our test suites and ran them in parallel on LambdaTest, and it handled hundreds of sessions without slowing down. It made releasing features faster while keeping test coverage high.
