AegisCeptor showing live traffic

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.

See every request

Pause and edit

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

Pause and edit

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.

Mock any API

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.

Ask your AI assistant

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.

Questions

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. The install command handles this for you. If you install the DMG by hand, 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.
