AI Performance Testing: Why We Built LoadMagic

AI Performance Testing should remove the grind of correlation, script debugging, and setup work. This is the origin story behind LoadMagic and the engine we built to turn recordings into runnable tests.

AI Performance Testing is more than a buzzword for us. It started as a lived problem and a promise to fix it. This origin story is the short version of why LoadMagic exists and why we believe Performance Testing needs an AI layer.

In plain terms, AI Performance Testing uses automation and intelligence to handle the tedious parts of scripting so humans can focus on test design, outcomes, and insights.

Performance Testing, without the unnecessary pain.

25 years in the trenches of Performance Testing

Our founder spent more than 25 years in Performance Testing across government systems, banks, retailers, and modern cloud platforms. Different projects, same story. The tools were powerful, but the work around them never stopped.

Correlation. Script debugging. Repetitive setup work that adds zero insight, just time. Every engagement brought the same heavy lifting.

The tinkerer mindset

Instead of accepting tool limitations, he kept asking, "What if we could make this better?" That led to plugins, automated workflows, and pushing tools like JMeter far beyond how they were meant to be used.

The turning point inside JMeter

Working deep inside JMeter made one thing clear. It is one of the most widely used Performance Testing tools in the world, but it is full of work that should be automated. That is when it clicked.

AI Performance Testing as the missing layer

This was not just one person's problem. It was everyone's problem. Performance Testing was crying out for AI to absorb the grunt work while keeping humans in control.

Traditional vs AI Performance Testing

Over the years, the same challenges kept appearing: fragile scripts, manual correlation, and rising maintenance costs as systems evolved.

We've documented these differences in a dedicated side-by-side comparison explaining how traditional Performance Testing differs from AI Performance Testing in practice.

What LoadMagic does today

LoadMagic.ai started as a passion project to scratch our own itch. Today, it is an AI Performance Testing engine that helps testers turn recordings, HAR files, and scripts into correlated, runnable tests in minutes, not days.

  • Ingests recordings, HAR files, and JMeter or Locust scripts.
  • Identifies dynamic values and drafts correlation rules.
  • Validates candidates across runs and explains each change.
  • Outputs runnable tests you can review, adjust, and ship.

Built to support testers, not replace them

LoadMagic is not about replacing performance testers. It is about removing the grind so we can focus on thinking, testing, and learning faster.
