Web platform for load testing. Manage your test scenarios, run existing scripts, and automatically analyze system performance.

Core insight

Bring Your Own Infrastructure

Maintain full ownership of your infrastructure and security. Our agent technology runs directly in your environment, ensuring that data never leaves your firewall while delivering advanced intelligence and analytics.

  • Total infrastructure control
  • Agent-based intelligence
  • Security remains in-house
  • Zero third-party data access

Core insight

Test your application, not your VPN tunnel.

Performance testing over a VPN introduces artificial bottlenecks. Our approach guarantees that through local execution, you measure only the real performance of your application, not the limits of an internet connection.

  • Home-field testing
  • Zero internet jitter
  • Clean performance signals
  • Rapid diagnostic feedback

Core insight

Start from the scripts you already trust.

Seamlessly leverage your existing .jmx assets. Teams with thousands of tests don't have to rewrite a single line of code, moving from legacy setups to cloud scale on day one.

  • Full .jmx compatibility
  • No rewrite marathons
  • Immediate value delivery
  • Reliable legacy scaling

Core insight

Buy saved time, not virtual-user hours.

Traditional solutions sell memory allocation and VUH, forcing you to track unit consumption. We offer an unlimited tool for testing and decision-making, shifting the focus from technical math to business outcomes.

  • Unlimited testing cycles
  • Predictable release costs
  • Business-outcome focus
  • Zero capacity anxiety
01 / 04

Your new workflow

Create the test in the right context

Project, team, labels, test plan, criteria. Set the context first so every run has clear ownership and stays understandable later.

Your new workflow

Run

Run the test when it matters. The Agent executes the test plan on the load generator, the scheduler keeps the rhythm, and the results flow back into Load Test Lab. Without the Agent, manual import still works.

primary path

The app sends the request, the Agent runs the test, and syncs the results back.

Your new workflow

Evaluate against criteria

After the run finishes, the app creates an evaluation. It checks metrics, criteria, and status so the result becomes a clear decision.

Your new workflow

Compare, report, move forward

Finally, you compare against a baseline, share the report, and keep the history. The next release then builds on saved context, not gut feeling.

Grow without rewriting

Start from your current scripts, not from a new migration.

Prove the value on top of what you already have first. Scale team access, runs, and automation only when it makes sense.
