Hermes Intercept On The F

🪽 Hermes: Intercept on the Fly!

The ultimate DevTools extension for frontend developers who need full control over HTTP traffic — without touching backend code.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━

🎭 HTTP Mocking
Create custom mock responses for any API endpoint. Define status codes, headers, and JSON bodies. Organize mocks into groups and toggle
them on/off instantly. No proxy servers, no code changes — just intercept and respond.

📡 Network Monitor
Real-time view of all fetch and XHR requests happening on the page. Inspect request/response bodies, headers, and timing — all within
the DevTools panel.

🔴 Request Recording & Playback
Record real API traffic and replay it later — even across different environments. Smart normalized path matching handles dynamic IDs
(UUIDs, numeric IDs) automatically. Batch domain replacement lets you switch between staging, dev, and production with one click.

🔀 Microfrontend Redirect
Redirect module federation manifests and static assets at the network level. Point remote microfrontend URLs to your local dev server
(or vice versa) without modifying source code. Works with any Module Federation setup.
