Developer Tools
HTTP & API traffic inspector for Android
Busymate DevTools for Android
Inspect every request your apps make — right on your Android phone.
System-wide capture powered by Android's VpnService, HTTPS decrypted only for the domains you choose, streaming live to your dashboard — no computer, no Wi-Fi proxy, no cables.
The app is currently in testing on Google Play — if the listing isn't available for you yet, sideload the APK directly.
Open the dashboard
Quick start
From install to live capture in minutes
Four quick steps — the in-app guided setup walks you through each one.
- 01
Sign in
Create a free Busymate account with Google or email — it pairs the app to your device.
- 02
Add your domains
List the domains you want to decrypt. Everything else stays end-to-end encrypted.
- 03
Run the guided setup
Allow the capture notification, install the certificate generated just for you, and approve Android's VPN consent — one screen at a time.
- 04
Capture & inspect
Flip capture on and requests stream in live — tap any one for full headers and body.
Real-time feed
See requests as they happen
Every request/response pair streams into a live feed — method, URL, host, status and byte count, grouped and filterable by type. No computer, no Wi-Fi proxy setup.
Full detail
Drill into headers and bodies
Open any request for the full picture — URL, method, timing, and separate Request and Response tabs with headers, query parameters and the formatted body.
Consent first
Nothing is captured until you say so
The first launch explains what gets captured, where it's stored and how to stay in control. Capture starts only after you've read it and agreed — and you can stop it any time from the home screen.
Guided setup
The fiddly parts, made step-by-step
Notifications, your personal CA certificate and Android's VPN consent are handled by a guided wizard with a narrated walkthrough video — no digging through Settings on your own.
You stay in control
Busymate DevTools is built for inspecting traffic from apps and sites you own or are authorized to debug. Capture is always opt-in and you decide exactly what gets decrypted.
Capture is opt-in
Nothing is captured until you explicitly turn it on and accept the on-screen consent.
HTTPS only for chosen domains
Decryption is limited to the domains on your SSL list — add or remove them at any time.
A personal CA, on your device
Decryption uses a CA certificate generated just for you, installed as a user certificate. On rooted devices you can optionally install it system-wide.
Stop and remove anytime
Turn capture off from the home screen and remove the VPN and certificate from Android settings whenever you like. Synced captures are deletable.
Privacy first
Traffic is captured on-device by Android's VpnService — nothing routes through our servers. Captured data can include sensitive values such as tokens and credentials, so only inspect domains you understand and control. Synced captures are stored under your own account and can be deleted at any time. Read the Android privacy policy.
Ready to debug on the go
- Android 7.0 or later
- A free Busymate account (sign in with Google or email)
- No root required — root only unlocks optional system-wide decryption
Your whole phone's traffic, one live feed
Busymate DevTools captures every app's HTTP and HTTPS traffic right on your Android phone and streams it to the live dashboard. Pick the domains you care about, flip capture on, and debug from anywhere.
System-wide capture via VpnService
Android's VpnService routes the whole phone's traffic through the app — every app, DNS and TCP alike, captured on the device itself. No computer required.
Decrypts only what you allow
TLS is decrypted only for hosts on your SSL list, using a CA certificate generated just for you — installed as a user certificate. On rooted devices it can optionally go system-wide to reach apps that ignore user CAs. Everything else passes through untouched.
Live on your dashboard
Every request streams to your private dashboard in real time — inspect on a bigger screen, search, tag, mock, and export to HAR.
PAC mode, when a VPN won't do
Prefer a proxy? PAC mode gives the device its own proxy auto-config URL — set it on your Wi-Fi network and traffic routes through your personal Busymate proxy instead of the on-device VPN.
Agent-ready over MCP
Everything the phone captures is queryable and scriptable by AI agents over the MCP server — and BusyBro, the built-in AI teammate, already knows your traffic.
Remote-managed, in your language
Capture settings, SSL lists and mock rules push to the phone live from the dashboard — no reinstall, no update. And the whole app speaks 14 languages.
