From terminal to live feed in one command

Un comando. El tráfico de Chrome aterriza en el mismo feed en vivo — sin certificados que instalar.

A terminal window running "bmc start" that reports Chrome attached and capture live; the prompt line extends as a dashed stream into a mini dashboard card with green status codes. Two Chrome browser devices sit behind the terminal, and a BusyBro chat exchange with a confirm check fills its lower half. $ bmc start ✓ chrome attached · capture live live 200 201

Por qué bmc

The simplest capture source

El camino más rápido de «abrir Chrome» a «inspeccionar cada petición» — y también puede moldear ese tráfico.

Cero configuración de confianza — literalmente ninguna

Como bmc lee el DevTools Protocol, el tráfico ya está descifrado. Nada entra en un llavero, nada lanza avisos; la captura empieza en cuanto arranca Chrome.

Dispositivos de navegador con nombre

Un demonio en segundo plano gestiona perfiles de Chrome independientes como dispositivos con nombre — arranca, detén y programa cada uno desde la terminal, el panel o una llamada MCP. Tus navegadores se vuelven parte de la flota.

Simula y muta, en local

El mismo motor JS aislado que impulsa el proxy corre contra tu sesión real de Chrome: reescribe peticiones, sintetiza respuestas y mira cada cambio aterrizar visible en el feed.

BusyBro en tu terminal

Un chat REPL con scrollback nativo que conoce los dispositivos de esta máquina. Pídele crear un navegador, abrir una URL, correr una comprobación — las acciones piden confirmación y las respuestas se basan en tu captura real.

No vuelvas a tocarlo

El demonio se actualiza solo cuando está inactivo, informa su build en vivo y se reinicia a petición desde el panel o MCP. Es infraestructura que se mantiene sola.

How it works

Reads Chrome traffic after TLS

bmc attaches to Chrome over the DevTools Protocol — the same wire DevTools itself uses — so it sees requests exactly as the browser does: already decrypted.

Ruta de datos: TLS termina dentro de Chrome; bmc lee eventos ya descifrados del DevTools Protocol y transmite las entradas a la API de ingesta de Busymate, llegando al dashboard, MCP y la exportación HAR. chrome --remote-debugging TLS termina aquí GET api.example.com 200 POST auth.example.com 201 GET cdn.example.com 304 ws:// Network.* ya descifrado bmc entradas + cuerpos source: cdp POST /ingest dash.busymate.dev · feed en vivo mcp.busymate.dev · browser_* export_har · las mismas entradas
  1. 01

    Its own Chrome, per folder

    bmc start launches a dedicated Chrome with its own profile and its own debug port for the current directory. Each folder is an independent device — run it in two folders and you get two fully separate browsers.

  2. 02

    Attach over the DevTools Protocol

    It connects to Chrome's debug port over a WebSocket, auto-attaches to every tab, and enables the Network domain — the same wire Chrome DevTools itself uses. No extension, no proxy in the path, nothing injected into pages.

  3. 03

    Events become entries

    Request, response and timing events are correlated into the same entry shape every Busymate source uses, with headers and bodies (up to 1 MB per body) pulled straight from the browser — after Chrome already decrypted them.

  4. 04

    Batched into one feed

    Entries are batched and posted to the ingest API about once a second. The folder pairs as a real Busymate device, so its traffic lands in the same dashboard, the same filters, the same MCP tools and the same HAR export as every phone.

No certificates

Capture without a root CA

TLS terminates inside Chrome, and bmc reads on the browser's side of it. There is no man-in-the-middle to trust — so there is nothing to install, and nothing for pinning to detect.

A proxy debugger decrypts HTTPS by re-signing it with its own certificate authority — which means installing that CA, trusting it in a keychain, and losing the apps that pin their certificates. bmc skips the whole problem: the DevTools Protocol hands over each request after Chrome has already decrypted it.

Capture paths compared: CDP, MITM proxy, on-device VPN
What it takesbmc (CDP)Proxy (MITM)iOS / Android app
Root CA to installNoneYes — trust the proxy CAYes — on-device CA, decrypting only domains you opt in
Network setupNonePoint each client at the proxyNone — an on-device VPN tunnel
Pinned certificatesUnaffected — nothing sits in the TLS pathPinned apps refuse the proxy CAPinned apps stay encrypted (metadata still visible)
What it seesThe Chrome it launches — every tabAny app or script you point at itEvery app on the phone
Best forWeb apps, SPAs, agent-driven browsingBackends, scripts, browsers on other machinesMobile apps, in the field

Each path is first-class: the proxy and the phone apps exist precisely for the traffic CDP can't see. Use bmc for browsers, the proxy for anything you can point at it, and the apps for whole-phone capture.

Browser automation

Drive the browser. See every request.

Every bmc browser is remote-controllable over MCP — an AI agent or a script can open pages, read them and act, while capture records every request the session makes. That combination is the point.

Drive and read the page

browser_open
Navigate the browser to a URL.
browser_targets
List the open tabs and pick the one to drive.
browser_snapshot
A compact accessibility-tree snapshot — the page as structured text, built for agents.
browser_screenshot
A PNG of the active page.
browser_eval
Run JavaScript in the page. Placeholder variables are resolved server-side from the device's env, so an agent can fill a login form without ever seeing the password.
browser_cdp
Raw DevTools Protocol access for everything else — owner-gated.

Browser profiles

Built-in Chrome, Brave and Edge profiles plus custom ones authored once in the dashboard — per-OS binaries, default flags and a flag catalog every machine's bmc resolves the same way.

  • list_browser_profiles
  • get_browser_profile
  • upsert_browser_profile
  • delete_browser_profile

The daemon, remotely

Live build, uptime and logs without SSH; list every named browser on a machine; restart or hot-update the daemon while running captures keep capturing. One switch arms or disarms it all, per device.

  • get_cdp_daemon_status
  • get_cdp_logs
  • list_cdp_instances
  • restart_cdp_daemon
  • update_cdp_daemon
  • set_device_cdp_control

Remote control is opt-in per device and permission-gated; capture keeps flowing either way.

GodBrowser

Una identidad de dispositivo coherente, cada solicitud capturada

GodBrowser es un Chromium anti-fingerprint que da al navegador una identidad de dispositivo coherente y con aspecto real. Es un perfil de navegador integrado en bmc, así que un agente puede ejecutar una persona y capturar su tráfico en el mismo feed en vivo que tus teléfonos.

Selecciona GodBrowser con un solo flag y bmc lo controla mediante el mismo DevTools Protocol que cualquier otro dispositivo de navegador: inspecciona cada solicitud que hace la persona —ya descifrada, sin CA raíz, sin proxy— y las transmite a tu feed de Busymate. GodBrowser presenta a bmc como su compañero de inspección de solicitudes para exactamente este emparejamiento.

Una identidad, toda de una pieza

El user-agent, la pantalla, WebGL, canvas y audio, el locale y la zona horaria concuerdan con la persona, y TLS/JA4, UA-CH y los códecs se alinean con el dispositivo declarado antes de que se ejecute una línea de JavaScript. Como lo plantea GodBrowser: un dispositivo real, no uno disfrazado.

Semillas deterministas

El flag --bot-profile deriva una identidad de dispositivo completa a partir de una cadena semilla. Cambia la semilla, cambia el dispositivo: repetible y reproducible, así que una persona se reproduce exactamente igual.

Personas por plataforma y navegador

Windows, macOS, Linux, iOS y Android combinados con Chrome, Safari, Firefox, Samsung Internet y Edge, seleccionados con --bot-os y --bot-browser. Su base es un Chromium 151 parcheado.

Clúster, API y MCP

GodBrowser se ejecuta en tu propio clúster de nodos, controlado desde código, su API o un cliente de IA, y ofrece su propio servidor MCP remoto. Los proxies se asignan por perfil de forma determinista; las sesiones se sincronizan entre máquinas mediante Redis.

Ejecuta una persona, captura su tráfico
bash
# GodBrowser is a built-in bmc browser profile — pick it per device:
bmc create ios-persona --browser godbrowser -- \
  --bot-os=ios --bot-browser=safari --bot-profile=seed-42 --start

GodBrowser es uno de los perfiles integrados de bmc, junto a Chrome, Brave y Edge: seleccionarlo con --browser godbrowser es toda la configuración. bmc resuelve el binario, expone sus flags de persona, empareja el dispositivo como un “God Browser” distinto y etiqueta su tráfico capturado como gdp para que destaque en el feed. No se inyecta nada en GodBrowser: bmc lo controla mediante el DevTools Protocol, y su capa anti-fingerprint vive en el núcleo del navegador, así que permanece intacta bajo automatización. Ambas herramientas son nativas de MCP: el servidor MCP remoto de GodBrowser y el de Busymate hacen que un mismo agente pueda controlar personas y leer su tráfico en una sola sesión, cada una tras su propio token basado en consentimiento.

What people build

One tool, four jobs

Agent-driven QA

An assistant opens your staging site, walks the flow and screenshots what it sees — while the network feed shows exactly what broke, with full request and response bodies.

Debug a SPA

Watch XHR and fetch calls stream live with headers, bodies and timings while you click through the app. The history survives a reload — no DevTools-tab archaeology.

Capture an OAuth flow

Redirect chains, tokens and callbacks recorded end to end — including on providers whose pinned certificates a proxy can't open.

Work a signed-in page

The folder's Chrome profile keeps its session between runs; snapshot and eval read the page while capture documents every request behind it.

FAQ

The sceptical questions

Does bmc need a certificate or a proxy?

No. It attaches to Chrome over the DevTools Protocol and reads traffic after Chrome has decrypted it. There is no root CA to install, no keychain trust prompt, and no proxy settings to change.

Does it work with certificate pinning and HSTS?

Yes. Pinning defends the TLS connection between Chrome and the server — bmc never touches that connection; it reads inside the browser. HSTS, corporate device policy and managed keychains are equally unaffected.

Does it modify pages or the sites I visit?

Capture injects nothing — bmc listens to Chrome's own network events. It also launches its own Chrome with its own profile, so your everyday browser is never touched.

Can it run headless or in CI?

Yes. Anything after -- goes straight to Chrome (for example --headless=new), and CDP_USER_JWT or CDP_PAIR_EMAIL and CDP_PAIR_PASSWORD sign in without opening a browser.

Which browsers does it support?

Chromium-family browsers: built-in Chrome, Brave, Edge and Chromium profiles, plus custom profiles you author in the dashboard. Anything that speaks the DevTools Protocol.

What about traffic outside the browser?

bmc only sees the Chrome it is attached to. For backends and scripts use the Busymate proxy; for whole-phone capture use the iOS or Android app — everything lands in the same feed.
