Overview
CloudCut SuperSonic moves huge files at line rate. A Rust transfer engine splits uploads into dozens of parallel parts (32 by default, tunable to 128), verifies each with SHA-256, and resumes automatically from any failure.
A minimal native desktop app (Tauri 2 + React) on macOS and Windows, a headless CLI for automation, and a Cloudflare Worker that orchestrates R2 and can stream downloads while the upload is still in flight.
Capabilities
Massively parallel
32 parts by default, configurable from 8 to 128, to saturate your link.
Resume anywhere

Per-part verification
SHA-256 checksums on every part for end-to-end integrity.
Stream-while-upload
A Cloudflare Worker streams downloads from R2 before the upload finishes.
