See every request your Mac makes.Natively fast.

Meet ix, an HTTP(S) debugging proxy for macOS, built in Rust with GPUI. Now in early alpha.

We’ll only write to you about the alpha and launch. Privacy.

Built for ProMotion. We budget 8.3 ms for each frame, which is what a 120 Hz display needs.

What you'd expect from a debugging proxy, made easy to use.

Native and fast

Written in Rust and drawn with GPUI, ix is a real Mac app. You won't find a web view or a bundled browser runtime inside.

Inspect HTTPS traffic

You choose which hosts to read. A certificate made on your Mac decrypts those, and everything else passes through still encrypted.

Stays out of the way

When a request fails, you can see why. Your proxy settings are restored when ix quits, even after a crash.

Built for developers

Press / to filter, read the headers, bodies and timing, then work with a flow: copy it as cURL, export HAR, edit and resend it, or pause it at a breakpoint.

Secure by design. Local-first.

A debugging proxy can read your traffic, so yours stays with you. Nothing leaves your Mac unless you send it.

Decrypts only what you choose
Only the hosts on your list are read. Everything else passes through still encrypted.
Keys stay on your Mac
Your certificate is made on your Mac. Only your account can read its private key, and the key never appears in a capture, log or export.
Listens to this Mac only
The proxy binds to loopback, 127.0.0.1 and ::1, so other machines on your network can't reach it.
No account needed
Captured traffic is stored on your Mac and leaves only when you export it. You never have to sign in.
