Full Chromium browsing — not a headless stub.

Why it exists

Most automation stacks bolt a driver onto someone else’s browser.
NTXM Browser mini is the browser and the control plane: a native desktop Chromium app with a built-in REST server on http://127.0.0.1:9090.

Open windows and tabs, navigate, read page HTML, and expose the API remotely with Cloudflare — from any language that can speak HTTP.

Control panel — server status, health, and Cloudflare tunnel

Quick start

1. Install and launch NTXM Browser mini.
2. The control page opens automatically (http://127.0.0.1:9090/control).
3. Try the API:

# Health
curl.exe http://127.0.0.1:9090/health

# List windows & tabs
curl.exe http://127.0.0.1:9090/windows
curl.exe http://127.0.0.1:9090/tabs

# Open a tab
curl.exe -X POST "http://127.0.0.1:9090/tab/new?url=https://example.com"

# Navigate the active tab
curl.exe -X POST "http://127.0.0.1:9090/navigate?window=1" -d "https://news.ycombinator.com"

# Read URL / HTML
curl.exe "http://127.0.0.1:9090/url?window=1"
curl.exe "http://127.0.0.1:9090/content?window=1"

In-app docs live at http://127.0.0.1:9090/ while the browser is running.

Automation API

Base URL: http://127.0.0.1:9090
Target with ?window= and ?tab= (defaults to the active window / tab).

Essentials

Tiny Python example

import requests

BASE = "http://127.0.0.1:9090"

print(requests.get(f"{BASE}/health").json())

r = requests.post(f"{BASE}/tab/new", params={"url": "https://example.com"})
print(r.json())  # {"ok": true, "new_window_id": 1, "new_tab": ...}

html = requests.get(f"{BASE}/content", params={"window": 1}).text
print(html[:200])

Remote access

Enable a Cloudflare quick or named tunnel from the control page (or settings.json).
With a public URL you can call the same endpoints from another machine — turn auth on before exposing the API.

Requirements

• Windows 10 / 11 (x64), or macOS on Apple Silicon (arm64)
• Release packages include Chromium / CEF runtime assets
• Optional: cloudflared for remote tunnel (cloudflared / cloudflared-darwin-arm64)
