overview

Load Rift

Load Rift is a Tauri desktop app for importing Postman collections and running local k6 load tests. The app keeps the workflow local: import a collection, configure traffic and runtime variables, run k6, watch live metrics, then export an HTML report.

What it does

Load Rift turns a Postman collection JSON file into a generated k6 script in src-tauri/src/importing/script.rs. The React workspace in src/app/App.tsx coordinates the user flow, while Rust commands in src-tauri/src/commands/ parse collections, validate settings, run smoke checks, launch k6, stop runs, and export reports.
