HTTPeep seamlessly captures HTTP/1.1, HTTP/2, and HTTPS (MITM) traffic. It automatically groups requests by TCP connection, visualizes HTTP timing, and provides multi-dimensional filtering to easily locate the requests you care about.
The true power of HTTPeep lies in its composable rule engine. Match traffic by domain, path, headers, or method, and build an action pipeline to Map Local, Forward, Delay, or Reject. Create robust rules, combine multiple actions, and export them to share with your team.
Need to test an endpoint directly? Use the integrated HTTP client to manually construct requests, test APIs on the fly, and even import your cURL or Fetch commands instantly.
We care about aesthetics as much as performance. Choose between meticulously crafted light and dark themes that fit perfectly into your OS environment.
HTTPeep features a Built-in MCP Server designed for AI agents. It works flawlessly with tools like Claude, Cursor, GitHub Copilot, and includes a CLI for scripted operations and CI/CD integration.
