Test AWS Amplify reliability with Gremlin Failure Flags. Inject latency and errors into rendering functions to validate fallback pages.
Server-side rendering quietly converts a static site into a live application. The mental model rarely follows. Teams keep treating an AWS Amplify deployment as static hosting, which is famously reliable, while every page view now depends on compute that calls APIs and can stall.
A slow API behind a single component doesn't degrade one widget. It delays the entire rendered response. Visitors see a blank page rather than a partially working one, and search crawlers see a timeout. One misbehaving data source looks exactly like the whole site being down.
Gremlin reaches the render path with Failure Flags. Inject latency into a data fetch and watch what your visitors get. Inject an error and confirm whether your fallback renders cached content, a degraded view, or nothing at all.
Serving something imperfect beats making a visitor wait, but only if someone has verified the fallback actually triggers.
Dependencies: Failure Test
Simulate a failed dependency by dropping all network traffic to the dependency.
Dependencies: Latency Test
Recreate poor network conditions by delaying all network traffic to a dependency by 100ms.
Unreliable Networks - Dependencies
Simulate unreliable network conditions when communicating with dependencies by adding latency to API calls. Test whether your users are affected when dependency response times degrade.
* Failure Flags works wherever you can add the SDK to your application and run the Gremlin sidecar. Not every language and platform combination has been individually tested, and not all are officially supported. Check our compatibility documentation for what's verified, or get in touch if you don't see your runtime.
