What it does
Ntropi is a developer tool that empowers frontend engineers to simulate real-world errors and network latency instantly. It provides live mock APIs directly from the CLI, allowing you to test UI resilience without waiting for a backend. By simulating server timeouts and status code errors in real-time, you can build robust error handling before writing a single line of backend code. It eliminates hardcoding temporary data and allow you to test your frontend against actual network conditions.
Ntropi is a free developer tool that empowers frontend engineers to simulate real-world errors and network latency instantly.
