& no-code tests

Run it from code, CI, or your AI agent

The browser is one way. Paste a k6 script, upload your JMeter plan, or let an AI agent drive tests over MCP.

BRING YOUR SCRIPTS

import http from 'k6/http';

export const options = {
  vus: 500,
  duration: '5m',
};

export default function () {
  http.get('https://your-app.example.com');
}

Run the k6 or JMeter scripts you already have, unchanged, from 25+ cloud regions.

CONNECT YOUR AI AGENT

{
  "mcpServers": {
    "loadfocus": {
      "url": "https://mcp.loadfocus.com/api"
    }
  }
}

Point any MCP-compatible agent, like Claude or Cursor, at the LoadFocus MCP server. It can create, run, and analyze load tests for you.

Trusted by developers and teams worldwide
Hear what they have to say.

“With LoadFocus, we achieved a 40% reduction in setup time, plus far more comprehensive charts than our past testing tools.”

Kevin WrightCoursinator

“We used LoadFocus to run a comprehensive suite of load tests, from anonymous homepage visits under heavy load to authenticated user journeys. The ability to upload and execute complex JMeter JMX files allowed us to simulate highly specific interactions. The combination of powerful test execution, flexible integration with JMeter, and detailed performance metrics has made LoadFocus an essential part of our QA and scaling strategy. Highly recommended for teams looking to simulate real-world load and uncover performance weaknesses before they hit production.”

Frequently asked questions

Is there a free plan?

Yes. The free plan lets you run cloud load tests without a credit card. Upgrade when you need more virtual users, longer tests, or AI analysis.

Do I need to write code to run a load test?

No. You can configure and run cloud load tests entirely in the browser. If you prefer code, upload JMeter JMX files or k6 JavaScript and they run unchanged.

Where do the tests run from?

From 25+ cloud regions around the world, so you can simulate traffic from the places your users actually are.

What does the AI analysis do?

On paid plans, every test run can be explained in plain English: what the response times and error rates mean, where the bottlenecks are, and what to fix, tailored to your tech stack.

Can my AI agent run load tests?

Yes. Connect any MCP-compatible agent, like Claude or Cursor, to the LoadFocus MCP server and it can create, run, and analyze load tests for you.
