Features


Memory usage in context

Different API clients are built using different technologies, which can impact resource usage. Native applications typically use less memory than browser-based tools.

ReqKit (native)
< 10 MB
Lightweight desktop client
~50–150 MB
Browser-based client
~300–800+ MB

Memory usage varies depending on workload, open requests, and background processes. Values shown represent typical ranges observed in common usage scenarios.


Performance

ReqKit is built as a native application on both platforms, designed to be lightweight and responsive. Its performance is evaluated through real end-to-end scenarios and memory profiling, reflecting typical day-to-day API workflows.

In practice, this translates to fast startup and a consistently low memory footprint. During a 5-minute automated test session, memory usage remains below 10 MB, even when handling larger payloads, authentication flows, and UI interactions.
