Web Scraping with Python in 2026: Best Libraries and Anti-Bot Strategies

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.

from playwright.sync_api import sync_playwright

def scrape_with_playwright(url):
    with sync_playwright() as p:
        browser = p.chromium.launch(headless=True)
        page = browser.new_page()
        page.goto(url, wait_until="networkidle")

        data = page.query_selector_all(".job-item")
        results = []
        for item in data:
            title = item.query_selector("h2").text_content()
            results.append(title)

        browser.close()
    return results
python
import httpx
from selectolax.parser import HTMLParser

def scrape_static(url):
    resp = httpx.get(url, headers={"User-Agent": "Mozilla/5.0"})
    tree = HTMLParser(resp.text)

    for node in tree.css(".listing"):
        print(node.text())

Many sites have hidden or public APIs that make scraping unnecessary:

url = "https://www.freelancer.com/api/projects/0.1/projects/active/?query=python"
data = httpx.get(url).json()
python
import random

def get_random_headers():
    browsers = [
        "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36",
        "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36",
    ]
    return {
        "User-Agent": random.choice(browsers),
        "Accept": "text/html,application/xhtml+xml",
        "Accept-Language": "en-US,en;q=0.9",
        "DNT": "1",
    }
python
import time

class AdaptiveLimiter:
    def __init__(self, min_delay=1.0, max_delay=5.0):
        self.min_delay = min_delay
        self.max_delay = max_delay
        self.current_delay = min_delay

    def wait(self):
        time.sleep(self.current_delay)

    def on_success(self):
        self.current_delay = max(self.min_delay, self.current_delay * 0.9)

    def on_block(self):
        self.current_delay = min(self.max_delay, self.current_delay * 1.5)
