Simple Interceptor

Simple Interceptor = Postman + Charles, on your iPhone.

Capture, inspect, and replay HTTP/HTTPS traffic — anywhere, anytime, without a desktop. Whether you're debugging an API on the go, reverse-engineering a third-party SDK, or verifying your app's network behavior in the field, Simple Interceptor gives you the power of professional desktop tools in a single mobile app.

— CAPTURE & DECRYPT HTTPS TRAFFIC —
• Real-time interception of all HTTP and HTTPS connections
• Built-in MITM proxy with automatic CA certificate generation
• View full request & response headers, bodies, and timing
• Decode gzip, deflate, and Brotli compressed responses automatically
• Filter by domain, HTTP method, status code, or full-text search
• Domain whitelist/blacklist rules for focused capture sessions

— BUILD & SEND REQUESTS (like Postman) —
• Craft custom HTTP requests with any method, headers, and body
• Import cURL commands directly — paste from docs, Slack, or terminal
• Inspect full responses with syntax-highlighted body preview
• Re-send captured traffic to reproduce or modify requests instantly
• Request history with iCloud sync across all your devices

— EXPORT & SHARE —
• Convert any captured request to a ready-to-run cURL command
• Copy headers, bodies, or full responses to clipboard
• Share diagnostic logs for team collaboration

— EXTRAS —
• NFC tag reading and writing (text, URL, custom MIME)
• Apple Sign-In with iCloud profile sync
• Unified log viewer with source and severity filtering
• Step-by-step certificate installation guide

— WHO IS IT FOR? —
• Mobile developers testing APIs without a laptop
• QA engineers verifying network behavior on real devices
• Security researchers analyzing HTTPS traffic
• Backend developers debugging webhooks and callbacks
• Anyone who needs Charles or Postman but only has an iPhone

No Mac required. No USB cable. No complicated setup. Just install, tap Capture, and start inspecting.

Privacy first — your traffic data stays on your device unless you choose to sync via iCloud.
