A skill for AI agents. OpenCode, Claude Code, Cursor, OpenClaw and beyond. Search the web with SearXNG, browse with Camofox, bypass protections with CloakBrowser. All self-hosted, free, unlimited.

Why it exists

browser-search is a SKILL — an instruction set for AI agents like OpenCode, Claude Code, Cursor, OpenClaw and others. It teaches your agent how to search and browse the web using three orchestrated open source tools.

The problem? The web is hostile to automation. Cloudflare, Akamai, DataDome and other anti-bot systems block simple requests. Modern sites use heavy JavaScript, lazy loading, and client-side rendering. One single solution is not enough.

browser-search orchestrates three open source tools into a single search and browsing system designed for AI agents. Each tool has its role, orchestrated by the skill with escalation logic, automatic selection, and ready-to-use integration:

  1. SearXNG — metasearch engine for the search phase (multi-source, JSON)
  2. Camofox — browser navigable via REST API for standard sites
  3. CloakBrowser — stealth browser for anti-bot protected sites

The typical flow: the agent first searches with SearXNG, then browses the results with Camofox (or CloakBrowser if the site is protected).

Benefits

  • 100% free, self-hosted, unlimited. No API keys to buy, no subscriptions, no rate limits. Everything runs on your machine, Docker and npm. Unlimited usage, zero cost.

  • Lightweight, runs anywhere. Built and tested on a Raspberry Pi — if it runs there, it runs everywhere. Minimal resource consumption, no heavy infrastructure needed, runs 24/7 on low-power hardware.

  • Search + browse in one kit. No manual integration needed. Searching and browsing are two distinct phases, both covered.

  • Automatic navigation escalation. If Camofox gets blocked by Cloudflare/Akamai, the agent automatically switches to CloakBrowser.

  • Smart performance. SearXNG for the search phase (milliseconds). Camofox and CloakBrowser are only used to browse the sites that actually need it.

  • Automatic agent choice. The AI agent decides which tool to use: SearXNG for initial search, Camofox for browsing, CloakBrowser if the site is protected. Zero human intervention.

  • Deep Research mode. The skill instructs the agent to go beyond superficial answers: explore multiple angles, cross-verify sources, cover every aspect, and never cut corners.

  • Fully customizable. The SKILL.md is plain text. You can edit the core rules, add your own, remove what you don't need. Adapt it to your workflow, your team, your standards.

  • Native stealth. CloakBrowser automatically detects Cloudflare, Akamai, DataDome, Imperva, PerimeterX, and DDoS-Guard challenges, and waits for them to resolve before extracting content.

  • Works with any agent. The SKILL.md is written for OpenCode, but the logic is identical for any AI agent. Same README, same package.json, everything works everywhere. Just ask your agent how to convert the skill for its environment.

How it works

Phase 1 — Search with SearXNG

Docker container on localhost:8080. Metasearch engine that queries Google, Wikipedia, Bing, DuckDuckGo and many others simultaneously. JSON output with titles, snippets, and URLs.

Example:

curl -s "http://localhost:8080/search?format=json&q=largest+llm+benchmark+2026"

The agent now has a list of URLs to visit and autonomously decides whether to browse them with Camofox or CloakBrowser based on the site.

Phase 2 — Browse with Camofox

Docker container on localhost:9377. Exposes a full Firefox browser through a REST API. The agent can create tabs, navigate, click, scroll, execute arbitrary JavaScript, and structure data.

Includes: Mozilla's Readability.js for extracting clean articles, removing nav, sidebar, and ads (~70% token savings).

Main commands:

# Create tab and navigate
curl -s -X POST "http://localhost:9377/tabs" \
  -H 'Content-Type: application/json' \
  -d '{"userId":"bot","url":"https://example.com"}'

# Read snapshot (accessibility tree)
curl -s "http://localhost:9377/tabs/<tabId>/snapshot?userId=bot"

# Execute JavaScript
curl -s -X POST "http://localhost:9377/tabs/<tabId>/evaluate" \
  -H 'Content-Type: application/json' \
  -H "Authorization: Bearer $CAMOFOX_API_KEY" \
  -d '{"userId":"bot","expression":"document.title"}'

Phase 3 — Browse with CloakBrowser (when Camofox isn't enough)

npm package based on Playwright + cloakbrowser. Launches a Chromium browser with advanced fingerprinting to bypass Cloudflare, Akamai, DataDome and other anti-bot systems. Automatic challenge detection with wait and retry.

Available scripts:

  • cloak-fetch.mjs — universal fetch with challenge detection
  • cloak-script.mjs — custom Playwright script execution

Example:

node scripts/cloak/cloak-fetch.mjs "https://protected-site.com"
node scripts/cloak/cloak-fetch.mjs "https://protected-site.com" --proxy socks5://... --geoip

Why both Camofox and CloakBrowser?

Because speed and stealth are a tradeoff, and the right tool depends on the site.

Camofox — fast, structured, persistent. Camofox wraps Camoufox (a C++-level Firefox fork) in a REST API with an always-warm browser. After a ~1-3s cold start, every request is near-instant. Its accessibility snapshots are ~90% smaller than raw HTML, with stable element refs (e1, e2, ...) for reliable interaction. It handles the ~90% of sites that don't use advanced anti-bot protection: articles, docs, search engines, standard web pages.

CloakBrowser — stealth, anti-bot, on-demand. CloakBrowser launches a fresh Chromium instance per request (~1-3s startup each time). It uses advanced fingerprinting, proxy support, geoip, and automatic challenge detection to bypass Cloudflare, Akamai, DataDome, Imperva, PerimeterX, and DDoS-Guard. It is the last resort for the ~10% of sites that block Camofox.

Real-world numbers:

Tool Cloudflare standard Cloudflare Turnstile DataDome
Camoufox (Camofox engine) up to ~92% [¹] ~65-78% [¹] 60-75% [¹]
Playwright Stealth ~70-80% [¹] ~40-55% [¹] ~30-50% [¹]
  • CloakBrowser applies 58 C++ source-level patches and scores 0.9 reCAPTCHA v3 (human-level, server-verified), passing all major anti-bot tests including Cloudflare Turnstile and FingerprintJS [²]
  • Camofox cold start: ~1-3s (one-time, then ~0ms per request via warm REST API) [³]
  • Playwright/Chromium cold start: ~0.5-6s (every launch, varies by environment) [⁴]

Camofox handles the fast path. CloakBrowser handles the edge cases. Together they cover the entire web with no gaps. The agent decides which to use.

docker run -d --name camofox-browser --restart unless-stopped \
  -p 9377:9377 \
  -e CAMOFOX_API_KEY=your-key \
  camofox-browser:latest

Ask your AI agent to handle the details. Each tool has its own integrated documentation.

What this skill does NOT do

  • Social media. Instagram, Facebook, TikTok, LinkedIn, and Twitter/X require login. browser-search does not attempt to browse them.
  • Download files. It is read-only (except for explicit screenshots).
  • Bypass paywalls. Does not circumvent payment or login systems.

Get involved

browser-search is open source and free. If you find it useful:

  • ⭐ Star the repo — helps others discover it
  • 🐛 Open an issue — report bugs or suggest features
  • 🔀 Submit a PR — fix, improve, extend
  • 💬 Share it — with your team, on Reddit, Twitter, Discord
  • 🧠 Adapt it — fork it, tweak the SKILL.md, make it yours
