What is unique about LoadNinja's approach to load testing?

Unlike protocol-based tools, LoadNinja uses actual real browsers at scale. Your agent can trigger scenarios that execute scripts inside native browsers, ensuring your performance metrics accurately reflect the true end-user experience including client-side execution.

Can I stop a running test through my agent if I see performance degradation?

Yes. Use the `stop_test_run` tool with the active Run ID. Your agent will dispatch an immediate halt command to LoadNinja, stopping all physical load processes and allowing you to analyze the metrics captured up to that point.

How do I check my account's virtual user (VU) limits?

The `get_account` tool retrieves your subscription details and strict runtime VU limits. Your agent will report your current usage caps, ensuring you stay within your performance testing budget.
