Frontend Resilience,
Quantified.
Qwilow isn't just a testing tool—it's a growth engine. We help you find the friction points that kill retention on low-end devices and unstable networks.
Engineered Failures
The Chaos Toolkit
Simulate any real-world failure mode directly in your browser. No server-side changes required.
Network Latency
Simulate 2G, 3G, or custom jitter with millisecond precision.
API Failures
Inject 404, 408, 500, or 503 errors into specific endpoints.
Malformed Data
Fuzz your JSON responses to test frontend data handling.
WebSocket Drops
Simulate intermittent connectivity in real-time streams.
Device Emulation
Hardware Constraints
Your local environment is a lie. Test your app on the hardware your users actually own.
CPU Throttling
Simulate budget SoC performance on a multi-core desktop.
Memory Pressure
Simulate OOM scenarios and low-RAM device constraints.
Battery State
Test UI changes when Low Power Mode is detected.
Thermal Throttling
Simulate frame-rate drops due to device overheating.
