Max Concurrency

Control how many tests run in parallel during a test run.

By default, tests run with maximum concurrency, up to the limit available on your plan. Higher concurrency leads to faster test runs, which is especially useful for large test suites or frequent executions.

If needed, you can lower the concurrency to avoid overwhelming certain environments or services.

You can set the Max Concurrency value in Settings → Account → Runner. This setting controls the default concurrency across your test runs.
