Know exactly where your API breaks before users do
Our AI models real-world traffic patterns from your OpenAPI spec, runs realistic load scenarios, and tells you where your system fails, why it fails, and what to fix before launch.

The demo uses simplified scenarios. Full tests use AI-generated traffic patterns that mimic real user behavior and production usage.
Full reports include breaking point detection, traffic headroom, bottleneck analysis, and fix recommendations.

What you learn
before you launch
AI analyzes your OpenAPI spec to generate realistic traffic scenarios. Each test reveals critical insights about where and why your API fails under real-world conditions.
These insights are derived from AI-generated, real-world traffic scenarios — not synthetic scripts.
The exact traffic level where latency or errors spike
Database, CPU, memory, or upstream dependency
How much real-world growth your system can handle
What to change first to safely scale
Four test scenarios that reveal how your API performs
Every test suite runs four distinct scenarios automatically. Each one stresses your API differently to uncover specific failure modes and performance characteristics.
Baseline Performance
Establishes normal behavior under light load to catch basic issues
Traffic Ramp
Gradually increases load to find your maximum stable throughput
Spike Scenario
Sudden traffic bursts reveal how your system handles unexpected demand
Chaos Testing
Injects artificial latency, connection failures, and traffic bursts to test how your API handles real-world failure conditions and recovers gracefully
