omk-crawl 2.0.1

Smart web crawling toolbox — 6 adapters, auto-escalating router

omk-crawling

Smart web crawling toolbox — 6 adapters, one router.
Fetch → Crawl → Browser → Extract → Convert → Mobile. Auto-escalates until it works.

omk-crawl https://example.com — one command. TLS detection → auto-escalation → unified result.

Demo

1. Auto-Escalation (verbose)

2. Tool Discovery

3. Diagnose (dry-run)

4. JSON Output

5. Python API

6. Headless Browser Test (Playwright + Chrome)

Why omk-crawling?

Web crawling never ends with one tool. A site might block your TLS fingerprint, require JS rendering, hide behind Cloudflare, or need a full LLM agent to navigate a login flow. omk-crawling routes across 6 adapters automatically (4 in the escalation chain), escalating from the lightest to the heaviest until the data is yours.

curl_cffi (0ms browser) → crawl4ai (render) → scrapling (stealth) → browser-use (LLM agent)

Quick Start

CLI

omk-crawl https://example.com                    # auto-escalate
omk-crawl https://example.com --tool curl_cffi   # force specific tool
omk-crawl https://example.com -o out.md          # save markdown to file
omk-crawl https://example.com --json             # JSON output
omk-crawl https://example.com -v                 # verbose escalation log
omk-crawl https://example.com --no-robots         # skip robots.txt check
omk-crawl https://example.com --min-delay 2.0     # 2s between same-domain requests
omk-crawl --diagnose https://example.com         # dry-run: what would we try?
omk-crawl --tools                                # list installed/missing tools
omk-crawl report.pdf                             # file → markdown (markitdown)

Python

from omk_crawl import crawl

# One-liner with auto-escalation
r = crawl("https://example.com")
print(r.markdown)       # LLM-ready markdown
print(r.summary())      # [ok] https://example.com | via curl_cffi | HTTP 200 | 42ms

# Verbose escalation
r = crawl("https://protected-site.com", verbose=True)
#   [omk-crawl] [1/4] Trying curl_cffi...
#   [omk-crawl]   ✗ curl_cffi: blocked — TLS fingerprint block
#   [omk-crawl] [2/4] Trying crawl4ai...
#   [omk-crawl]   ✓ crawl4ai succeeded (1204ms)

Pipeline

from omk_crawl.pipeline import Pipeline

result = (
    Pipeline()
    .fetch()
    .extract_css("div.product", {"title": "h2", "price": ".price"})
    .to_markdown()
    .run("https://shop.example.com")
)
print(result.extracted)  # [{"title": "...", "price": "..."}]

Async

import asyncio
from omk_crawl import crawl_async

async def main():
    r = await crawl_async("https://example.com")
    print(r.markdown)

asyncio.run(main())

Tool Router

6 adapters implemented, 4 in the auto-escalation chain. Additional tools (scrapy, crawlee, scrcpy, curl-impersonate, insane-search) are documented in references/ for manual use.

| Need | Tool | Layer | Status | |------|------|-------| | Single blocked URL (403/WAF) | insane-search | ① Fetch | documented | | TLS/JA3 fingerprint block | curl-impersonate / curl_cffi | ① Fetch | adapter | | Anti-bot stealth + Cloudflare | scrapling | ① Fetch | adapter | | Large-scale classic crawl | scrapy | ② Crawl | documented | | Queue · auto-scale · proxy | crawlee | ② Crawl | documented | | Web → LLM Markdown · deep crawl · MCP | crawl4ai | ② Crawl | adapter | | LLM agent drives browser | browser-use | ③ Browser | adapter | | Learn extraction from examples | autoscraper | ④ Extract | adapter | | PDF/Office/image/audio → Markdown | markitdown | ⑤ Convert | adapter | | Android-only data | scrcpy | ⑥ Mobile | documented |

Responsible Use

This toolbox includes TLS fingerprint impersonation and anti-bot bypass capabilities. Use responsibly:

• Respect robots.txt and site Terms of Service before crawling.
• Rate-limit your requests — don't overwhelm target servers.
• Only crawl data you're authorized to access. Bypassing authentication or accessing protected data without permission may violate laws (CFAA, GDPR, etc.).
• These tools are intended for legitimate research, development, and data extraction within legal boundaries.

This product includes software developed by UncleCode (https://x.com/unclecode) as part of the Crawl4AI project (https://github.com/unclecode/crawl4ai).
