Playwright vs Puppeteer vs Selenium for Web Scraping (2026)
Playwright vs Puppeteer vs Selenium for web scraping in 2026: how each talks to the browser (CDP, its own protocols, W3C WebDriver), browser and language coverage, how each waits for elements, a first Playwright scrape, our own side-by-side lab on the same Chromium 141 (launch time, extraction, waits, per-command round trip of 1.0 ms for Puppeteer, 2.2 to 2.6 ms for Playwright and 9.0 ms for Selenium, memory including Playwright Python's 169 MB Node driver), running them at scale, cost, and when GcrawlAI is the simpler route.

Camoufox Tutorial: Scrape Without Getting Detected
A Camoufox tutorial for 2026: what the open-source Firefox build for scraping is and how it sets fingerprint values in the engine, when it is the right tool, how to install it (the browser is a separate download from GitHub), a first Playwright-style scrape with a content check, proxies with geoip, what our own install audit of camoufox 0.5.9 found (browser 158.0.1-beta.41, Playwright 1.62, 285 fingerprint presets, a fetch that fails where GitHub is blocked), the limits to plan around, and when GcrawlAI is the simpler route.
Nodriver and Undetected ChromeDriver: Python Tutorial
A Python tutorial for nodriver and undetected-chromedriver in 2026: how the patched-ChromeDriver approach and the driverless CDP approach differ, where each project stands (undetected-chromedriver 3.5.5 frozen since February 2024, nodriver 0.50.99 from October 2026, the zendriver fork), how to install both (the distutils import failure on Python 3.12+ and the setuptools workaround), a first nodriver scrape, the quiet migration traps (select() returning None, .text versus .text_all, JPEG screenshots), our own lab results on Python 3.13 and Chromium 141, the limits, and when GcrawlAI is the simpler route.
