Mockpod

What is Mockpod?

Mockpod is a local proxy server that lets you capture, inspect, and mock HTTP/HTTPS traffic on your Mac. It's ideal for testing edge cases, simulating backend failures, and developing frontend applications without a fully functional API.

Whether you're building an app that depends on external APIs, testing how your product behaves when the server fails, or investigating network traffic — Mockpod gives you full control.

Features

📡

Traffic Interception

Capture and inspect all HTTP/HTTPS requests and responses flowing through your proxy.

📋

Rule-Based Mocking

Define rules to mock API responses based on URL patterns, headers, or body content.

⚡

High-Performance Proxy

Lightweight proxy server built with SwiftNIO for minimal overhead.

🍎

macOS Native

Built with SwiftUI, optimized for macOS 14+ with a native, polished interface.

🔴

Record Mode

Start recording to capture live traffic and save it as a rule set. Edit individual responses afterward and instantly reuse them for mocking.

🔍

⚠️ Important: First Launch

Since Mockpod is distributed outside the Mac App Store, macOS Gatekeeper may quarantine it on first launch. If the app won't open or shows a warning, run this in Terminal:

xattr -cr /Applications/Mockpod.app

Then right-click the app, select Open, and macOS will remember your choice. You can launch it normally afterward.

Quick Start

Get up and running in four steps:

Launch Mockpod – Open the application.
Configure proxy – Point your system or browser proxy to the local server (default port: 8080).
Create a Rule Set – Define how requests should be intercepted and mocked.
Start the proxy – Begin intercepting traffic. Pin important requests to keep them at the top.
