WebReaper.Stealth.CloakBrowser

CloakBrowser stealth Chromium fork backend for WebReaper. One-liner .WithCloakBrowser() that finds (or downloads from upstream) the CloakBrowser binary, launches it with the fork's recommended flags, and wires its CDP endpoint into WebReaper.Cdp.

The first concrete satellite of the ADR-0054 stealth-backend pattern.

What CloakBrowser solves

C++ source-level fingerprint patches make the browser indistinguishable from a real user's. Designed for sites that block automation:

Challenge Outcome
Cloudflare Turnstile, reCAPTCHA v3, FingerprintJS, BrowserScan Silent pass; challenge never appears
reCAPTCHA v2 image grid, hCaptcha (interactive puzzles) Not handled by stealth; needs a separate captcha-solving service
DataDome on aggressive sites Partial; vendor recommends headed mode + residential proxies (use WithProxy(...))

Install

dotnet add package WebReaper.Stealth.CloakBrowser
# WebReaper.Cdp is pulled transitively

Quick start

using WebReaper.Builders;
using WebReaper.Stealth.CloakBrowser;

var engine = await ScraperEngineBuilder
    .CrawlWithBrowser("https://protected-site.example/catalog")
    .Follow("a.product-link")
    .Extract(productSchema)
    .WithCloakBrowser()             // one-liner: find/download/launch/wire
    .WriteToMongoDb(connStr, "scrapes", "products")
    .BuildAsync();

await engine.RunAsync();

License acknowledgment

CloakBrowser's binary license: free to use, no redistribution. This satellite:

  • Does NOT bundle the binary in the NuGet package (cannot redistribute).
  • DOES download it from CloakHQ's own GitHub releases on first use (same legal model as playwright install, winget, brew install --cask).
  • Logs a license-acknowledgment line on first install (via the wired ILogger); CLI surface (per ADR-0055) gets a Y/n prompt.

See BINARY-LICENSE.md for the binding terms; by using this satellite you accept them.

How it composes

.WithCloakBrowser()
    │
    ├── CloakBrowserInstaller.EnsureInstalledAsync()  → finds/downloads to ~/.webreaper/stealth/cloakbrowser/
    ├── CloakBrowserLauncher.LaunchAsync(path)        → uses CdpLaunchHelpers; spawns with stealth flags
    └── builder.WithCdpPageLoader(endpoint.CdpUrl)    → connects WebReaper.Cdp to the running browser

Composes naturally with WithProxy(...) (residential proxies for the hardest sites) and the LLM action resolver from WebReaper.AI (.WithLlmActionResolver(...); semantic clicks like "dismiss popup" work through stealth).

10.0.0: initial release. First concrete satellite of the ADR-0054 stealth-backend pattern. WithCloakBrowser() one-liner; detects pre-installed CloakBrowser binary or downloads from upstream (legal model = `playwright install`), launches with the fork's recommended flags, wires CDP into WebReaper.Cdp. CloakBrowser solves invisible bot-checks (Cloudflare, reCAPTCHA v3, FingerprintJS) via C++ source-level fingerprint patches. License-acknowledgment logger one-liner on first install; CLI surface (ADR-0055) gets a Y/n prompt. Requires WebReaper 10.0.0 + WebReaper.Cdp 10.0.0.
