Everything runs locally on your Mac. Rockxy captures traffic from macOS apps, browsers, API clients, local runtimes, simulators, and mobile devices that you route through the proxy. It also gives you the tools to replay, modify, export, compare, and share what you capture without leaving the app.

What Rockxy Helps You Do

Capture requests and responses from browsers, desktop apps, local servers, simulators, and remote devices once they are routed through Rockxy. Replay captured requests, edit them before sending, compare responses, and export cURL or HAR when you need to reproduce an issue outside the original client. Use the Developer Setup Hub and platform-specific guides to configure iOS simulators, Android devices, browsers, API clients, and local runtimes. Rockxy documents what is automatic, what is manual, and where certificate trust, proxy settings, or platform constraints still apply.

Core Workflows

Capture and inspect traffic

Rockxy captures HTTP, HTTPS, WebSocket, and GraphQL-over-HTTP traffic and presents it in a native request inspector with headers, body, query, cookies, raw view, timing, comments, and protocol-specific detail.

Modify and replay requests

When you need to test an edge case, you can repeat a request immediately, edit it before sending, pause traffic with breakpoints, map a request to a local file, rewrite a destination, or change headers on the fly.

Debug real environments

Rockxy is especially useful when browser DevTools are not enough: native apps, SDK traffic, CLI tools, iOS simulators, Android devices, or a backend process making requests outside the browser.

Export and share evidence

Use native session files when you want to preserve Rockxy-specific context, or HAR when you need to hand traffic to another tool or attach it to a bug report.

Read This First

Install Rockxy, trust the certificate, start capture, and inspect your first request. macOS requirements, certificate trust, local data locations, and build-from-source notes. How HTTPS interception works, what trusting the root CA means, and where issues usually come from. Start with the in-app setup surface if you need to capture traffic from a specific runtime, browser, framework, or device.
