Browser agents and stealth cloud browsers for AI: run web tasks, fill forms, extract data.
Descripción del creador (original en inglés)
Web scraping & search for AI agents: extract, SearXNG search, rerank, robots compliance. No API key.
Estos tres nunca se combinan en una sola puntuación: las opiniones, las mediciones y la popularidad son cosas distintas.

CrawlEyes gives AI agents reliable full-text extraction (web_extract) and robust search (web_search) backends — the "eyes" that let agents see and read the web. Built and tested against Hermes Agent.
Also ships as a standard MCP server, so any MCP client (Claude Desktop, Cursor, other agents) can reuse the same search + extraction capabilities.
Most agent toolkits cover *one* slice of the pipeline. CrawlEyes is the rare all-in-one that you can actually run behind the Great Firewall without external accounts.
| Typical agent toolkit | CrawlEyes | |
|---|---|---|
| 🔍 Search | API key required, often blocked in CN | ✅ SearXNG (self-hosted) + Tavily keyless fallback — zero config, zero key |
| 📄 Extraction | Separate scraper, or Firecrawl SaaS | ✅ Built-in Crawl4AI full-text extract, ~89% noise removal |
| 🧠 Semantic rerank | Rarely included | ✅ Local fastembed rerank — no torch, ~50MB model |
| 🔌 MCP server | Often missing | ✅ Standard MCP tools (search + extract + deep_research + sitemap), any client |
| 🌐 China-friendly | Mostly English/GFW-blocked | ✅ Tested on a real mainland China server (baidu + yandex) |
Zero API keys. Zero external accounts. One command. CrawlEyes is the only toolkit in this space that combines search + extraction + semantic reranking + MCP in a single, China-friendly, self-hosted package.
| Capability | Where | Why it matters |
|---|---|---|
| Full-text extraction | scripts/crawl4ai_cli.py | Headless-browser scraping → clean Markdown; handles ~80% of JS/dynamic/UA-blocked pages |
| Content denoising (P1) | crawl4ai_cli.py --noise-filter | Prunes nav/ads/comments via Crawl4AI's PruningContentFilter — measured 24.6k→2.8k chars (~89% noise removed) on a typical article |
| Retry with backoff (P3) | crawl4ai_cli.py --retry N | Exponential backoff (1s/2s/4s) on transient failures |
| Browser session reuse (P4) | crawl4ai_cli.py --session NAME | Reuses the browser context across scrapes in one process — no cold-start per URL |
| Keyword-focused extraction | crawl4ai_cli.py --bm25 KEYWORD | Keeps only paragraphs relevant to a keyword (experimental — BM25 is English-centric; works best on English docs) |
| Search (primary) | SearXNG (self-hosted meta-search) | Privacy-friendly search aggregator |
| Search (fallback) | Tavily keyless API | Zero-config, no-key fallback when SearXNG is down/empty |
| Search orchestration | plugins/searxng-tavily/ | Hermes plugin provider: SearXNG first → auto-fallback to Tavily keyless; three-state circuit breaker (3 fails → 60s cooldown → half-open) + shared SQLite cache (TTL 3600s) |
| Semantic reranking (P2) | scripts/crawl_search_standalone.py | Local embedding rerank of search results with fastembed + BAAI/bge-small-zh-v1.5 (512-dim, no torch dependency, ~50MB, cached) — puts relevant results first. Measured: crawler-relevant items 0.817/0.732 float to top, irrelevant 0.302/0.139 sink |
| MCP server (P5) | scripts/mcp_crawl_server.py | Exposes search + extract + deep_research + sitemap as standard MCP tools (stdio default, or streamable-http for remote clients). Works in *any* MCP client, no Hermes dependency. Extracted content is sanitized against prompt-injection (strips invisible chars + prompt-hijack lines). Unified rate limiting + exponential backoff guard every tool (sliding window, per-tool cost) so concurrent agent calls can't hammer downstream services |
| Sitemap discovery (P1) | crawleyes/sitemap.py | sitemap(origin) → parses sitemap.xml (plain / gzip / index-recursion) with robots.txt fallback, returns a deduped URL map. Zero-key way to discover a site's URL surface for whole-site fetch or deep-research seeding |
| Multi-format extract (P0) | extract(..., format=) | markdown (default) / fit (denoised) / raw (unfiltered) / markdown_with_citations — pick the level of cleanup you need |
| RAG-ready interfaces | crawleyes/rag.py | One-liners markdown(url) / search_markdown(query) → clean, sanitized, LLM-ready Markdown for RAG corpora |
| Deep research | crawleyes/deep_research.py | deep_research(topic) → decomposes topic into sub-questions → searches → extracts → synthesizes a cited Markdown report. Optional LLM (any OpenAI-compatible endpoint); degrades to evidence-aggregate mode without one |
| Verification | scripts/ | Clean subprocess scripts to verify each backend end-to-end per Hermes profile |

/scrape endpointAlready using Firecrawl's Python SDK? Point it at CrawlEyes and keep your code:
.venv/bin/python -m crawleyes.firecrawl_api --port 8899 --host 127.0.0.1
from firecrawl import Firecrawl
fc = Firecrawl(api_url="http://127.0.0.1:8899", api_key="ignored") doc = fc.scrape(url="https://example.com") # → { markdown, metadata }
This is a pragmatic subset of the Firecrawl API — the core /scrape contract (success + data.markdown + data.metadata), backed by CrawlEyes' own extraction engine. It does not implement Firecrawl's async /crawl queue, /search, or /map — see the design notes for the rationale.
Copy plugins/searxng-tavily/ into a Hermes plugins dir, then:
hermes plugins enable web/searxng-tavily
hermes config set web.search_backend searxng-tavily
Set SEARXNG_URL in your Hermes profile .env to point at your SearXNG instance. If unset or unreachable, the provider automatically falls back to the Tavily keyless API (no API key required).
Note: the plugin only takes effect for newly started agent sessions.

record_success() is only called when SearXNG itself succeeds.pwd.getpwuid, not $HOME — which Hermes profiles override), so all profiles share one cache.
