Porthole

In-app network inspector for iOS/macOS. Captures HTTP/HTTPS and WebSocket traffic and lets you view it with a built-in SwiftUI viewer — no proxy, no certificates, no desktop app.

Fork of Proxyman/Atlantis. Original Atlantis streamed captured traffic over Bonjour to the Proxyman desktop app; Porthole removes that dependency and views traffic in-app instead.

• Removed the Bonjour transport layer and remote Proxyman integration
• Added a built-in SwiftUI viewer: traffic list + detail view
• Added body search and traffic filtering
• Added export as cURL command and HAR file
• Added clear/pause and a bounded in-memory store (Atlantis.trafficStore)
• Replaced the AtlantisSwiftUIApp example with PortholeExample, wired to the new viewer

• Automatic HTTP/HTTPS capture, no proxy or certificate trust needed
• WebSocket capture (URLSessionWebSocketTask)
• Built-in SwiftUI viewer: list + detail, search, filter
• Export as cURL command or HAR file
• Pause/resume and clear captured traffic

• iOS 16.0+ / macOS 11+ / Mac Catalyst 13.0+ / tvOS 13.0+ / watchOS 10.0+
• Xcode 14+, Swift 5.0+

import SwiftUI
#if DEBUG
import Atlantis
#endif

@main
struct MyApp: App {
    init() {
        #if DEBUG
        Atlantis.start()
        #endif
    }
}

UIKit: call Atlantis.start() in application(_:didFinishLaunchingWithOptions:).

struct DebugTrafficView: View {
    var body: some View {
        NavigationStack {
            AtlantisTrafficListView()
        }
    }
}

AtlantisTrafficListView() observes Atlantis.trafficStore and lists captured requests newest-first; tap a row for full request/response detail.

• Atlantis.trafficStore.clear() — wipe captured entries
• Atlantis.trafficStore.isPaused — pause/resume capture
• Atlantis.trafficStore.capacity — max entries held (default 500)

• cURL: from the detail view, or package.curlCommand()
• HAR: from the list's Export action, or Atlantis.trafficStore.exportHAR()

Example/PortholeExample demonstrates integration end to end.

• Debugging tools (Map Local, Breakpoint, Scripting) aren't supported — use a normal proxy for those.
• All captured data lives in memory only; nothing leaves the device and nothing persists after the app closes.
