Describe your test, get a real script

Write what you want to test in plain English and LoadFocus builds the script for you, in k6 or JMeter.
You get the actual script, not a black box. Read it in the built in code editor, check it for problems, run a single user smoke test to prove it works, and let AI fix what it finds before you run at full load.

Frequently asked questions

What does the analysis produce?

A written account of what happened in the run, the bottlenecks it can identify from the metrics, and specific things to change. It reads response times, error rates, throughput and percentiles rather than inferring from the test name.

How is this different from reading the charts myself?

The charts show what happened, the analysis proposes why. It correlates response-time degradation with the point in the ramp-up where it began, which is the part that takes longest to work out by hand.

Do the recommendations know my technology stack?

If you tell it. Set your stack and the output comes back as specific JVM flags, Nginx directives, database hints or framework settings. Without one you still get the analysis, phrased more generally.

Which tests can be analysed?

Cloud load tests, JMeter tests and k6 tests, using the results already stored for that run. You can analyse a past run as well as one you just finished, so there is no need to re-run a test to get a read on it.

Does running it cost anything?

Each analysis draws on your plan's AI credit allowance. The test results themselves stay available whether or not you run one, so the analysis is an addition to the run rather than a condition of seeing it.

How do I load test an AI application (RAG, LLM calls)?

Treat the model provider as a paid, rate-limited dependency: keep virtual users within its rate limits, budget the tokens a test will use, and add realistic think times. When responses stream, measure time to first token as well as total response time, and test the retrieval path (embeddings, vector search) separately so you can see which part slows down. LoadFocus runs these tests from JMeter or k6 scripts, and the AI analysis explains where the time went.
