Capture real user traffic
and transform the way you test
Capture real HTTP traffic from production and use it to build test scenarios.
LoadTester captures and anonymizes real user traffic, then replays it without manual scripting to validate system performance and bottlenecks.
Why does preparing for a performance test still take so much time,
even when you already have a testing tool?
Traditional performance testing requires teams to repeatedly write and update scripts, communicate business logic, prepare test data, and map variables. Whenever the service changes, much of this preparation has to be done again—adding significant time and effort before testing can even begin.
Excessive internal resource drain
Core engineers get tied up explaining application logic to external vendors. Add the tool learning curve, and teams lose time they could spend on their core work.
The data management dilemma
De-identifying sensitive data becomes a project bottleneck. Every test repeats the inefficiency of resetting and reprocessing data.
Disconnected test environments
Change one dynamic parameter and the whole test flow breaks. Even small changes force a full manual rewrite of the script.
Production traffic, captured as-is
Embed a Capture Agent in your WAS to collect traffic by copying it, minimizing the impact on your production service.
Control capture flexibly with sensitive-data masking, conditional filtering, and scheduling.
Sensitive data,
kept safe
Automatically detect PII with regex at the capture stage
to partially mask or remove it,
and fine-tune scrubbing rules by URL and method
conditions and by category.
Save specific traffic segments to build reusable test scenarios.
Save only the traffic segments you need and reuse them to build test scenarios.
You can also combine filters to extract precise user journeys.
Beyond a single request,
reproduce real user journeys
Save data transformation logic as reusable templates and automatically substitute dynamic parameters like tokens and session IDs in real time.
Feed API responses directly into subsequent requests to seamlessly validate end-to-end business flows.
Replay real traffic
at any load level you need.
Run your configured scenarios up to your target concurrent-user count or TPS.
Frequently Asked Questions

LoadTester is a performance and load-testing platform that captures and refines real user traffic from production and replays it in a test environment. Instead of designing virtual-user scenarios from scratch, it uses actual API call flows as test data and, after personal-data masking and dynamic variable mapping, can reproduce load at your target TPS and concurrent-user levels. Captured traffic can also be saved as snapshots and reused in later tests.
