Beo Echo – Unified tool for mocking, proxying, and replaying HTTP APIs

Summary: Beo Echo is an open-source platform that combines API mocking, HTTP request replay, proxy forwarding, and traffic logging into a single tool. It enables capturing real API requests, replaying them to reproduce issues, and mocking endpoints to support development workflows.

What it does

Beo Echo captures and replays HTTP requests, mocks API endpoints, and operates in proxy mode to forward traffic. It supports executing requests from both the browser and the server while managing multiple projects within one workspace.

Who it's for

It is designed for developers and teams needing to debug API integrations, especially when API clients are inactive or only available in production environments.

Why it matters

Beo Echo addresses the challenge of reproducing and debugging API requests by consolidating multiple tools into a single open-source solution that fits collaborative and multi-project workflows.
