Debug your iOS app.
No Mac required.
Pry lives inside your app. Captures every URLSession request, mocks responses, throttles connections — all on-device. No proxy, no certificates, no setup.
ContentView().pry() — that's it.
Why Pry?
Proxy-based tools were designed for a Mac-first workflow. Pry was designed for the way you actually debug — on device, in context, instantly.
The old way
- Install Charles or Proxyman ($50-$89)
- Configure proxy on your Mac
- Trust a self-signed certificate on device
- Pray it works through corporate VPN
- Switch to Mac every time you debug
- Lose context when you switch apps
Every. Single. Debug. Session.
The Pry way
ContentView()
.pry()- Works on cellular, VPN, corporate WiFi
- Debug on the go — no Mac needed
- Zero context switching — stays in your app
- 100% on-device, nothing leaves your app
- Free forever. MIT licensed.
Everything you need, on device
A full debugging suite that lives inside your app. No external tools, no context switching.
Free & Open Source
Every request. Every detail.
Pry hooks into URLSession at the foundation layer. No swizzling, no proxy, no certificate dance. Every request captured automatically.
- Timing breakdown: DNS, TLS, connect, TTFB
- JSON body with syntax highlighting
- GraphQL awareness, JWT decode, redirect chain
- Search, filter, sort, pin, swipe to copy cURL
Console & App Hub
Terminal-style console with colored log types. Plus a full App Hub with deeplink and push notification simulators, cookies, UserDefaults, device info, and permissions.
- Structured logs: info, success, warning, error, debug
- Deeplink monitor with URL builder simulator
- Push notification capture with APNs simulator
- Cookies, UserDefaults, device info, permissions
Breakpoints & Mocks PRO
Pause requests before they hit the server, or responses before they reach your app. Mock any endpoint with fake JSON. Replay and compare requests.
- Breakpoint on request or response
- Mock responses with custom status and delay
- Replay any captured request
- Compare two requests side by side
Performance & Export PRO
Live CPU, memory, and FPS metrics with anomaly detection. Export sessions as Postman Collection or HAR archive. Network throttle for testing slow connections.
- CPU, memory, and FPS with insights feed
- Session export: Postman Collection & HAR
- Network throttle: 3G, Lossy, Offline
- Protobuf decoder without .proto schema
Network Throttle
Simulate Slow 3G, Fast 3G, Lossy, or Offline.
Request Diff
Compare two requests side-by-side.
Replay
Re-send any captured request with one tap.
HAR Export
Export sessions for Chrome DevTools.
Postman Export
Generate ready-to-use Collections.
Protobuf Decoder
Raw decode without .proto schema.
Your data never leaves the device.
Not ours to see. Not ours to store.
100% On-Device
All processing happens locally. Intercepted requests, logs, and metrics never leave your phone.

Frequently asked questions
Is Pry Pro a subscription? +
No. Pry Pro is a one-time purchase. You get lifetime access to the current major version and all minor and patch releases within it. Future major versions may require an upgrade.
Can I use Pry Pro on multiple projects? +
Yes. A single-developer license covers unlimited projects built by the license holder. If you work in a team, each developer needs their own license.
Does Pry work with Alamofire / AFNetworking? +
Yes. Pry intercepts at the URLSession level, which is the foundation layer for Alamofire, AFNetworking, and virtually all iOS networking libraries. If it uses URLSession under the hood, Pry captures it.
Can I use Pry in TestFlight or debug builds? +
Yes. Pry is a debug tool — include it in debug builds and strip it from release builds using #if DEBUG or SPM build conditions. It has no server component, so there is nothing to disable.
What happens if I lose my GitHub access to PryPro? +
Open a private issue on the PryPro repository with your purchase receipt and we will re-add you. Access is tied to your purchase, not to a time-limited token.
Refund policy? +
Full refund within 14 days of purchase, no questions asked. Your repository access is revoked automatically on refund.
Can I see the Pro source code? +
Yes. Pry Pro is distributed as source code, not a compiled binary. You can step-through debug, adapt it, and submit feedback. Redistribution is not allowed by the license.
Does Pry send any data to your servers? +
No. Pry is entirely on-device. Nothing is ever sent to prytool.dev or anywhere else. The only network traffic Pry creates is the traffic your app is already making.
What happens after I buy Pro? How do I activate it? +
After purchase, you receive a GitHub collaborator invite to the private PryPro repo. Accept it, then add the PryPro package via SPM. Use .pryPro() instead of .pry() — that's the only change.
