HTTPeep

HTTPeep —— Next-Generation Cross-Platform HTTP Proxy Tool

HTTPeep is a professional-grade HTTP proxy and debugging tool built for developers who work with complex network traffic. It runs natively on macOS, Windows, and Linux.

What Truly Sets HTTPeep Apart

Most existing tools (Charles, Proxyman, HTTP Toolkit, etc.) suffer from two major pain points:

• Rules are scattered across separate panels (Rewrites, Mocks, Breakpoints, etc.), making it impossible to see the full picture when you have dozens of rules.
• All configurations are stored locally with no version control or easy sharing — switching machines means starting from scratch every time.

HTTPeep solves both problems elegantly:

1. Unified Execution Pipeline All rules live in a single, transparent execution pipeline. For every request, you can instantly see the complete flow:

• Rule matching ? Request modification ? Routing ? Response modification No more guessing which rule fired or in what order.

2. File-Based Rules with Native Git Support Every rule is stored as plain JSON or YAML files.

• Fully version-controlled with Git
• Easy to share with your team or open-source
• Clone the repository on a new machine and you’re ready to go instantly

Core Features

• Request & Response Rewrite: Modify headers, body, status codes, delay, or any part of the traffic on the fly.
• Breakpoints: Pause requests or responses for inspection and manual editing before they continue.
• Map Local: Map remote requests to local files or folders (perfect for frontend-backend separation or offline testing).
• Map Remote: Redirect requests to different remote endpoints or environments with one click.
• Mock Responses: Instantly create custom responses with static data or dynamic scripting.
• Advanced Matching Conditions: Match by Host, Path, Method, Headers, Query parameters, etc.
• Full Traffic Capture & Export: Record complete sessions and export in standard HAR format.

HTTPeep transforms proxy debugging from a fragmented, machine-bound experience into a structured, collaborative, and truly portable workflow.
