About Hermes: Intercept on the Fly!

πŸͺ½ Hermes: Intercept on the Fly! The ultimate DevTools extension for frontend developers who need full control over HTTP traffic β€” 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 β€” just intercept and respond. πŸ“‘ Network Monitor Real-time view of all fetch and XHR requests happening on the page. Inspect request/response bodies, headers, and timing β€” all within the DevTools panel. πŸ”΄ Request Recording & Playback Record real API traffic and replay it later β€” 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. πŸ”€ 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. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ⚑ Key Features β€’ Works in Chrome DevTools as a dedicated panel β€’ Per-host enable/disable toggle from the popup β€’ Network-level redirects (catches requests before JavaScript runs) β€’ Cross-environment recording playback with smart URL matching β€’ Import/export mocks and recordings as JSON β€’ Dark mode support β€’ Zero external dependencies β€” all data stays in your browser πŸ”’ Privacy Hermes stores all data locally in your browser using IndexedDB. No data is sent to external servers. Ever. πŸ› οΈ Built by developers, for developers.
