Heimdall
Nothing crosses the bridge unseen.
Heimdall stands between your phone and the network and reads everything that passes. What it captures it shows in a real Chrome DevTools Network panel — the same one you already know — while its own panels let you rewrite a response, mock an endpoint, hold a request at a breakpoint, or override it from a file. Where other proxies leave you to wire up proxies and certificates by hand, Heimdall drives the device for you.

Try it free
Version 0.6.0Apple hasn’t notarised this app, so on first launch macOS will say it can’t verify it. Open it from System Settings → Privacy & Security → Open Anyway. Everything runs on your own machine, and nothing phones home.
What it does
- — Show every request your phone makes in a real Chrome DevTools Network panel — synthesised from the live traffic, not a lookalike of it.
- — Rewrite requests and responses, mock an endpoint, hold a request at a breakpoint, or override a response from a file on disk.
- — Set the device up for you — point its proxy, push and trust a certificate over adb, even repackage an APK to trust your own — instead of leaving it to you.
- — Bring Android, iOS, and React Native debugging into one window, with the device’s console beside the traffic.
What it won’t do
- — Open an app that pins its own certificate without extra work. When a handshake fails, Heimdall shows it in red rather than hiding it.
- — Send your traffic to the cloud. Heimdall is a local proxy — what it captures stays on your machine, not on a server somewhere.
