Wire Snap transforms your iPhone and iPad into a zero-latency local HTTP server and webhook interceptor for mobile, web, and backend developers.
Powered by Apple Network framework (NWListener and NWConnection), Wire Snap runs directly on your device. It enables you to capture, inspect, filter, mock, and replay HTTP/REST and Webhook payloads sent from other devices, simulators, or cloud webhooks on the same local Wi-Fi network.
KEY FEATURES:
1. LOCAL HTTP SERVER & BONJOUR DISCOVERY
• Native TCP HTTP server running on a configurable port (default 8080).
• Instant Wi-Fi IPv4/IPv6 address detection with QR code sharing for rapid client pairing.
• Zero-configuration local network discovery with Bonjour (_wiresnap-http._tcp).
• Low memory footprint and high throughput streaming TCP parser.
2. REAL-TIME WEBHOOK INTERCEPTOR
• Intercept and test webhook payloads from Stripe, GitHub, RevenueCat, Firebase, Shopify, Discord, Slack, Svix, and Postmark.
• Built-in signature verification engine for Stripe (v1), GitHub (SHA-256), and Shopify HMAC.
• Instant payload inspection with Content-Length, Content-Type, and HTTP header analysis.
3. ADVANCED JSON & PAYLOAD VIEWER
• Syntax-highlighted JSON viewer with key/string/number/boolean color-coding.
• In-payload keyword search and structured node copy.
• Raw text viewer, Base64 decoder, and Byte/Hex inspector.
• One-tap "Copy as cURL" command generator for instant reproduction.
4. DYNAMIC ROUTE MOCKING & FAULT INJECTION
• Custom URL path matching (exact, prefix, wildcard, regex).
• Override HTTP response codes (200, 201, 204, 400, 404, 429, 500).
• Response body templating with dynamic variables (UUID, timestamp, ISO 8601, random values).
• Artificial latency injection (0ms to 3000ms) to test mobile UI loading states.
5. INSTANT REPLAY STUDIO
• Re-send captured requests directly from your device via URLSession.
• Edit headers, target URL, and JSON payload before dispatching.
• Side-by-side diffing of original vs. new HTTP response code, body, and round-trip duration.
6. FULL-BLEED HOME SCREEN & LOCK SCREEN WIDGETS
• Edge-to-edge iOS 17 and iOS 18 widgets designed to Apple Design Award standards.
• System Small (2×2): Instant live status, active port, and real-time request counter.
• System Medium (2×4): Server status, local IP address, total calls, and latest intercepted webhook.
• System Large (4×4): Comprehensive 4-card telemetry grid with latency and Bonjour stats.
• Lock Screen & StandBy accessories (Circular, Rectangular, Inline) for glanceable server monitoring without unlocking your device.
7. DEVELOPER EXPORT TOOLKIT
• Export captured sessions to standard HTTP Archive (HAR 1.2) for Charles Proxy, Insomnia, and Chrome DevTools.
• Auto-generate OpenAPI 3.0 YAML specifications from recorded traffic.
• Export Postman Collection v2.1 format for one-click import.
8. PRO CUSTOMIZATION & TOTAL PRIVACY
• 15 handcrafted alternate app icons (Cyber Cyan, Volt Gold, Matrix Green, Titanium Dark, Pure Studio, and more).
• Complete native localization across 20 worldwide languages.
• 100% on-device execution with zero cloud telemetry and absolute data privacy.
