ricibrowser

A lightweight two-engine browser automation module built entirely on the Chrome DevTools Protocol (CDP). No Playwright, no Puppeteer, no selenium.

Engines

Engine	Use case	Technology
Lightpanda (fast path)	crawl, recon, endpoint discovery, non-JS-heavy targets	Zig-based headless engine, CDP at `ws://127.0.0.1:9222`
CDP-Chrome (thorough path)	DAST, JS-heavy targets, auth flows, anti-bot	Custom CDP client driving the user's real installed Chrome

Install

pip install ricibrowser

# For the fast path (optional):
bash scripts/install_lightpanda.sh
lightpanda serve --host 127.0.0.1 --port 9222

# For the thorough path:
# Just have Google Chrome installed on your system.

Quick start

import asyncio
from ricibrowser import Engine, EngineConfig

async def main():
    engine = Engine(EngineConfig())

    # Fast path (Lightpanda) — crawl/recon
    page = await engine.fast_browse("https://example.com")
    print(f"Title: {page.title}")
    print(f"Text: {page.text[:200]}")
    print(f"Links: {len(page.links)}")

    # Thorough path (CDP-Chrome) — DAST/auth flows
    session = await engine.create_session()
    await session.navigate("https://example.com/login")
    await session.fill("#username", "admin")
    await session.fill("#password", "pass")
    await session.click("#login-btn")

    # Cookies persist across sessions via CookieJar
    await session.navigate("https://example.com/dashboard")  # authenticated!

    # JS evaluation in isolated world (never Runtime.enable on main world)
    count = await session.evaluate("document.querySelectorAll('script').length")

    # Network capture (opt-in, off by default)
    engine2 = Engine(EngineConfig(debug_network=True))
    session2 = await engine2.create_session()
    # ... browse ...
    flows = engine2.network.to_dict()

    await engine.close()

asyncio.run(main())

Stealth

navigator.webdriver suppressed via --disable-blink-features=AutomationControlled (Blink-level, not JS injection)
Uses the user's real installed Chrome (not bundled Chromium) — TLS/JA3 fingerprint matches a real Chrome release
Never calls Runtime.enable on the main world — isolated worlds only
Console.enable off by default — only enabled in explicit debug mode
Network.enable off by default — known CDP detection vector

Architecture

See ARCHITECTURE.md for the full design.
