The post provides code examples for scraping with Playwright and httpx, and introduces an adaptive rate limiter to handle anti-bot measures.", "body_md": "Web scraping in 2026 looks very different from 2020. Sites are smarter, anti-bot systems are more aggressive, and the legal landscape has evolved. Here's what actually works now.\n\n| Challenge | 2020 Solution | 2026 Solution |\n|---|---|---|\n| Bot detection | Rotate User-Agent | Fingerprint randomization + residential proxies |\n| CAPTCHAs | Manual solving | Turnstile/hCaptcha solvers |\n| JavaScript rendering | Selenium | Playwright (faster, more reliable) |\n| Rate limiting | Sleep between requests | Adaptive pacing + request signing |\n| IP blocking | VPN rotation | Residential proxy pools |\n\n``` python\nfrom playwright.sync_api import sync_playwright\n\ndef scrape_with_playwright(url):\n    with sync_playwright() as p:\n        browser = p.chromium.launch(headless=True)\n        page = browser.new_page()\n        page.goto(url, wait_until=\"networkidle\")\n\n        data = page.query_selector_all(\".job-item\")\n        results = []\n        for item in data:\n            title = item.query_selector(\"h2\").text_content()\n            results.append(title)\n\n        browser.close()\n    return results\npython\nimport httpx\nfrom selectolax.parser import HTMLParser\n\ndef scrape_static(url):\n    resp = httpx.get(url, headers={\"User-Agent\": \"Mozilla/5.0\"})\n    tree = HTMLParser(resp.text)\n\n    for node in tree.css(\".listing\"):\n        print(node.text())\n```\n\nMany sites have hidden or public APIs that make scraping unnecessary:\n\n```\nurl = \"https://www.freelancer.com/api/projects/0.1/projects/active/?query=python\"\ndata = httpx.get(url).json()\npython\nimport random\n\ndef get_random_headers():\n    browsers = [\n        \"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36\",\n        \"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36\",\n    ]\n    return {\n        \"User-Agent\": random.choice(browsers),\n        \"Accept\": \"text/html,application/xhtml+xml\",\n        \"Accept-Language\": \"en-US,en;q=0.9\",\n        \"DNT\": \"1\",\n    }\npython\nimport time\n\nclass AdaptiveLimiter:\n    def __init__(self, min_delay=1.0, max_delay=5.0):\n        self.min_delay = min_delay\n        self.max_delay = max_delay\n        self.current_delay = min_delay\n\n    def wait(self):\n        time.sleep(self.current_delay)\n\n    def on_success(self):\n        self.current_delay = max(self.min_delay, self.current_delay * 0.9)\n\n    def on_block(self):\n        self.current_delay = min(self.max_delay, self.current_delay * 1.5)\n```\n\n*Building scraping tools?
