MOBILE DEBUGGING · MACOS
Mobile bugs.
A clearer way to debug.
Bring real devices, Chrome DevTools and your coding agent into one workspace. Inspect the page, understand the failure, verify the fix.

FOR CODING AGENTS
Give every fix a device check.
Let your agent read a DOM snapshot, inspect errors and requests, then reload and capture the result. Structured JSON keeps scripts predictable.
SNAPSHOT / JSON
$ tapscope snapshot --interactive --json
{
"ok": true,
"command": "snapshot",
"data": {
"nodes": [
{"ref": "@e1", "role": "heading", "name": "Trail Notes"},
{"ref": "@e2", "role": "button", "name": "View route"}
]
}
}CONSOLE / JSON
$ tapscope console list --types error,exception --json
{
"ok": true,
"command": "console list",
"data": {
"events": [{"eventId": 12, "type": "error",
"message": "Route data could not be loaded"}]
}
}NETWORK / JSON
$ tapscope network list --failed --json
{
"ok": true,
"command": "network list",
"data": {
"events": [{"eventId": 13, "url": "/api/routes",
"failed": true, "status": 503}]
}
}Example CLI output; references are valid until the next snapshot in the session.
Connect your existing CDP tools
The local endpoint at 127.0.0.1:9222 connects Chrome DevTools MCP, Puppeteer and VS Code to the selected device.

Familiar panels. Actual devices.
Find your device in the sidebar, choose a page and open Chrome DevTools. Keep multiple targets in native window tabs.
Get the Mac app
Console
Read logs, inspect exceptions and evaluate JavaScript.
Network
Trace requests, response bodies and WebSocket activity.
Sources & breakpoints
Pause JavaScript and inspect the call stack and variables.
Storage
Inspect cookies, local storage and IndexedDB.
Screenshots
Capture the page from the app or save evidence with the CLI.
React DevTools
Planned for v1: inspect components, props, state and hooks.
DEVICE SUPPORT
A workspace for your mobile stack.
Planned v1 targets. Tapscope itself runs on macOS 15 or later.
| Target | Connection | Inspectable content |
|---|---|---|
| iPhone & iPad | USB | Safari, Chrome on iOS, inspectable WebViews |
| iOS over Wi-Fi | Network pairing | Paired devices with Web Inspector enabled |
| iOS Simulator | Xcode & simctl | Safari and WebViews in simulator apps |
| Android | USB & adb | Chrome and debugging-enabled WebViews |
| Network targets | CDP debug port | Chrome / Chromium, Node.js, Electron |
GET CONNECTED
Three steps to the page that matters.
Prepare your device
Enable Web Inspector on iOS or USB debugging on Android, then connect to your Mac.
Choose your target
Select the device, app and page in Tapscope. Use the setup checks when a target is missing.
Inspect and verify
Open DevTools or connect your agent. After the change, reload and check the result on the device.
SETUP NOTES
A good connection starts here.
A quick orientation. Full, searchable documentation follows in the documentation milestone.
iPhone & iPad
Connect by USB, unlock the device and trust the Mac. Enable Settings → Safari → Advanced → Web Inspector. A WebView must be inspectable; App Store and TestFlight apps are not supported.
Android & WebViews
Enable developer options and USB debugging. Install adb on the Mac and accept the device’s authorization prompt. WebViews require debugging to be enabled by the app.
iOS Simulator
Install Xcode and its command line tools. Create and boot an iOS simulator, open Safari and select its page in Tapscope.

FAQ
Before you connect.
Is Tapscope available yet?
Version 1.0 is in development. These pages describe the planned v1 feature set; the download will be enabled when a signed release is ready.
Can I use my coding agent?
The planned CLI works with agents that can run shell commands. Claude Code, Codex and Cursor can use JSON output; compatible MCP and CDP clients connect to the local endpoint.
Which computers can run Tapscope?
The first release is for macOS 15 or later. Windows is planned for later; Linux is a future experimental option. Xcode is required for iOS simulators and adb for Android.
Can I inspect any iOS app?
No. WebViews must be explicitly inspectable in developer-provisioned apps, for example with isInspectable on iOS 16.4+. App Store and TestFlight apps are outside the supported scope.
Does page data go through a cloud service?
Device debugging and the CDP endpoint run locally on your Mac. License activation and validation use Polar. The optional website live chat connects to tawk.to only after you choose Start chat; IP address, browser data and messages are then processed by that service, which may use cookies.
