The debugging proxy
made for Mac
See, pause, edit and mock every request from mobile apps, browsers and simulators. Built for developers and QA engineers.
14 days free · macOS 12+ · Apple Silicon

See every request
Live traffic from phones, browsers, simulators and terminals, grouped by device and domain. JSON trees, images, GraphQL, Protobuf, WebSockets and Server-Sent Events.

Pause and edit
Breakpoints on requests and responses. Change the method, URL, status, headers or body, then resume. Other traffic keeps flowing.

Mock any API
Answer a URL with your own response, with templates and conditions. Send production calls to localhost, rewrite headers, throttle to 3G or inject errors.

Ask your AI assistant
Connect Claude Code, Codex, Cursor, VS Code and more in one click. Ask why a request failed, or have it create mocks and breakpoints for you.

Connect anything
Phone over Wi-Fi with a QR code, Chrome, iOS Simulator, Android Emulator and terminal tools. Your Mac proxy settings stay untouched.
Find problems faster
GraphQL errors behind HTTP 200, security hints, waterfall timing, p50/p95 latency and alerts for failing calls.
Share with your team
Session files, HAR, bug reports with secrets masked, and copy as cURL, fetch, Python, Swift or Kotlin.
Private by design
Everything runs on your Mac. No account, no cloud, nothing is sent anywhere.

How does the trial work?
Download and use every feature for 14 days. No account or card needed. After that, the app asks for a license key.
How many Macs can I use?
A Lifetime license works on 2 Macs, a Yearly subscription on 1 Mac. Move it any time: choose Deactivate on this Mac in About, then activate it on the other one.
Which Macs are supported?
macOS 12 or newer on Apple Silicon (M1 and newer).
Why does macOS warn about the app?
AegisCeptor is not notarised by Apple yet, so we install it with one Terminal command that handles this for you. Prefer the DMG? Download it from the Releases page, drag it into Applications, then run xattr -dr com.apple.quarantine /Applications/AegisCeptor.app once.
Do I get updates?
Yes. Lifetime licenses get free updates. Yearly subscriptions get updates while active. The app checks for updates and installs them with one click.
