porthole

Porthole records your app’s URLSession requests, responses, and WebSocket frames in-process and shows them in a SwiftUI viewer.

A fork of Proxyman / Atlantis, with an on-device viewer instead of a desktop app.

Add via Swift Package Manager:

// Package.swift
dependencies: [
    .package(
        url: "https://github.com/sohandotgit/Porthole.git",
        from: "3.3.0"
    )
]

Start capture once at launch, in debug builds.

import SwiftUI
#if DEBUG
import Atlantis
#endif

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

    var body: some Scene {
        WindowGroup { ContentView() }
    }
}

Present the viewer anywhere.

import Atlantis

struct DebugMenu: View {
    @State private var showTraffic = false

    var body: some View {
        Button("Network Log") { showTraffic = true }
            .sheet(isPresented: $showTraffic) {
                NavigationStack {
                    AtlantisTrafficListView()
                }
            }
    }
}

• »cURL: copy a request as a curl command.
