What It Does

The Local Runner is a standalone desktop application that executes your API tests on your own machine or CI server. It connects to the Shift-Left API platform for test definitions and reports results back in real-time — while keeping all API traffic within your network.

Test execution with Shift-Left Engine (cloud) and local runner test pack management
