Side Impactor

Browser-based IPA signing and installation. Pair an iOS device over WebUSB, sign with your Apple Developer account, and install — all from a single web page.

Quick Start

bun install --ignore-scripts
bun run dev

Open http://localhost:5173.

Project Structure

Path	Purpose
frontend/	React + Tailwind SPA (Vite)
backend/	Cloudflare Workers relay
dependencies/webmuxd/	WebUSB usbmux/lockdown protocol library
wasm/openssl/	OpenSSL WASM (TLS + pair record generation)
wasm/libcurl-wasm/	libcurl WASM (Apple API HTTP via WISP proxy)
wasm/zsign-wasm/	zsign WASM (IPA re-signing)
scripts/	WASM native build scripts (Rust + Emscripten)

Build

# WASM dist bundles (copies pre-built src→dist, no compiler needed)
bun run build:wasm:dist

# Frontend production build (runs wasm:dist automatically)
bun run build:frontend

# Full WASM recompile from source (requires Rust, Emscripten, precompiled OpenSSL)
bun run build:wasm

Docker

bun run build:wasm:dist   # ensure WASM dists exist
docker build -t sideload-web .
docker run -p 3000:3000 sideload-web

Test

bun run test            # webmuxd unit tests
bun run test:frontend   # frontend vitest suite (141 tests)
