Real systems. Real behavior.

Test the systems you depend on.

Choose your starting point. Keep control of the details.

Websites & APIs

See what changes
under load.

Configure your verified target and method, then observe behavior with your existing monitoring.

When to use it: Before releasing a change to your website or API.
In RETROSTRESS: Choose the target, method, duration, and concurrent tests.
In your monitoring: Compare latency, error rates, and resource usage before and during the test.

Example test configuration

Observe the response with your own monitoring.

Infrastructure

Choose your authorized target, method, location, and duration. Save a repeatable packet sequence for your next test.

When to use it: After changing the configuration of infrastructure you operate.
In RETROSTRESS: Keep the target and test settings consistent between runs.
In your monitoring: Review connection behavior and resource usage under the same test conditions.

Example test progress

Custom packet sequences

A chain is a reusable sequence of network packets repeated during a test. Define the flow, timing, and payloads for your protocol.

When to use it: Your service expects a specific packet sequence.
In RETROSTRESS: Configure and save the steps. Inspect AI suggestions before accepting changes.
In your monitoring: Check whether your service handles the sequence as expected.

Packet sequence Example
