Introduction

Inspect HTTP Proxy Plus (ihpp) is a powerful, developer-centric reverse HTTP proxy and traffic inspector. It combines a high-performance Go backend with a modern Next.js web interface to provide real-time visibility, persistent history, and request manipulation capabilities for your HTTP traffic.

Project Origin​

ihpp is a modernized and enhanced version of the original inspect-http-proxy project. While the original was a robust CLI-focused tool, ihpp (the "Plus" version) adds a persistent database, a full web UI dashboard, and multi-proxy management to provide a more comprehensive debugging experience.

Whether you are debugging complex microservices, reverse-engineering APIs, or testing frontend integrations, ihpp provides the tools you need in a single, lightweight binary.

Why ihpp?​

Traditional tools like curl or browser DevTools are great, but they often lack:

  • Persistence: Re-inspecting a request from yesterday.
  • Searchability: Finding a request based on a specific JSON field or header.
  • Multi-tasking: Managing multiple proxy targets from a single interface.
  • Ease of Replay: Quickly modifying and re-sending a captured request.

ihpp was built to fill these gaps, providing a persistent "brain" for your HTTP traffic.

Key Features​

  • Multi-Proxy Management: Run multiple proxy targets simultaneously.
  • Persistent History: Searchable SQLite-backed history with FTS5.
  • Real-time Stream: Watch traffic as it happens.
  • Modern UI: Polished dashboard for deep inspection.
  • Request Builder: Modify and replay requests with ease.
  • Zero Configuration: Sensible defaults that work out of the box.
