Is the free run really free?

Yes: two minutes, one method, one target, no card and no trial expiry. It exists so you can see the report format and confirm that verification works before paying for anything. It is not a permanent free stresser: running generators costs money, and a service that gives away unlimited traffic is usually funded by traffic aimed somewhere you do not control.

What can I learn from a two-minute run?

Enough to see whether the endpoint, the network path and the verification flow behave as expected, and enough to get one latency percentile and one delivery ratio at a chosen rate. It is not enough to find the saturation point, because finding a knee needs a ramp and a ramp needs more than two minutes.

Why do I still need to verify the target on a free run?

Because the verification is what makes the traffic lawful, and the cost of checking is the same whether the run is free or paid. A free tier without verification would be an open door: the cheapest way to abuse a platform is to create free accounts and aim them at addresses nobody authorised.

What you get with the free stresser

A free stresser account gives you one concurrent test on the same 4 Tbps network paid plans use, with 30+ Layer 4 and 20+ Layer 7 methods and nothing locked. Most people use the free stresser to check one endpoint after a deploy, then compare the result with a Layer 7 stresser run.

Most people use the free run to check one endpoint after a deploy. If the report shows the behaviour you expected, you already have your answer without paying.

Free stresser limits, in plain numbers

Free stresser limits are about time, not methods: one test at a time and a short window. Paid plans raise the window to 5000 seconds and concurrency to three, which the pricing page lists in full.

Free stresser trial on a 4 Tbps network: How to read the report

The free stresser report shows delivery ratio, p95 and error classes. Read the first class that appears, keep the run in the stresser panel, and use it as the baseline for the next test.

For the request side of the same endpoint, run a Layer 7 stresser test and put the two reports next to each other.

Before your first stresser run

Own the target. Verify it through DNS or the panel before any traffic moves.
Pick one question. Does the endpoint fail, and at what rate? One method per run answers it.
Keep the report. The run lives in the panel so a later test can confirm the change.
