How to Optimize Proxy Bandwidth and Latency
Reduce proxy latency and bandwidth with caching, connection reuse, protocol tuning, regional placement, compression, and measurement.
Engineering
Puppeteer, Playwright, Selenium and headless Chrome, and what they take to run well.
Serverless Web Scraping with TypeScript and AWS
Build a reliable TypeScript scraper on AWS with Lambda, S3, DynamoDB, queues, and Playwright—plus a managed screenshot shortcut.
Load Balancing for Web Scrapers: Proxies, Sessions, and Workers
Scale compliant crawls across workers and proxies while keeping request rates, sessions, retries, and costs under control.
Optimize Proxy Bandwidth with Image and CSS Stubbing
Reduce proxy bandwidth by resizing, converting, compressing, and caching images. Learn when CSS stubbing helps, how to measure savings, and how to avoid broken pages.
n8n: Workflow Automation for Developers
Build reliable n8n workflows with code, deployment choices, source control, troubleshooting, and a direct ScreenshotNeo screenshot path.
Building an Educational Font Detection Tool
Learn how to design a font detection tool that teaches visual recognition, reports likely matches honestly, and helps readers check image and catalog limits.
Image, PDF, and Video Automation for Developers
Choose the right image, PDF, and video automation workflow by operation, formats, execution model, and credential handling, with runnable API examples.
Web Scraping Proxy Benchmarks: Why Regional Proxies Fail
Regional proxy benchmarks can pass connections while returning the wrong market. Learn how to measure geo accuracy, content correctness, speed, retries, and cost.
How to Make Headless Browsers Faster
Speed up Puppeteer and Playwright by measuring startup, waits, network, rendering, and concurrency without sacrificing correctness.
How DNS Certificate Authorization Works for Websites
Learn how CAA DNS records control certificate issuance, handle wildcards and subdomains, verify policies, and fix common CA errors.
Stealth Techniques for Browser Automation
Browser automation stealth is not invisibility. Learn what Playwright emulation can control, how detection spans multiple signal layers, and how to run reproducible tests you’re authorized to perform.
Using the Chrome DevTools Protocol with a Cloud Browser
Connect Playwright or Puppeteer to a hosted Chromium session over CDP, secure the endpoint, automate targets, and run it reliably in CI.
How Caching Works in Stagehand and Where It Breaks
Stagehand has server-side result caching and agent action replay. Learn how to tell them apart, configure each by version, and investigate misses or skipped custom tools.
Browser Session Persistence and MFA Automation
Persist Playwright sessions safely, restore every auth store, and automate MFA with test authenticators without weakening production security.
Setting Inactivity Timeouts for Browser Automation
Configure browser automation inactivity and operation timeouts correctly in Playwright MCP, Playwright, Selenium and Puppeteer.
Fintech Browser Automation on Your Own Infrastructure
Run browser automation for financial workflows on infrastructure you control. Set up Playwright, isolate credentials and sessions, and plan for operational and policy limits.
