Multi-Page Browser Automation: Pages, Contexts, Popups, and Multiple Users
Learn how to automate multiple tabs, popups, and isolated users with Playwright, with practical lifecycle, debugging, and reliability patterns.
Engineering
Puppeteer, Playwright, Selenium and headless Chrome, and what they take to run well.
Browser Identity and Persistent Profiles for Automation
Choose the right Playwright strategy for isolated tests, reusable logins, or a browser profile that survives restarts—and keep that state secure.
When Should You Host Your Own Browser Automation Infrastructure?
Decide whether to run Playwright or Selenium yourself by weighing privacy, network access, concurrency, coverage, operations, and total cost.
Reusable Browser Profiles for Authenticated Automation
Learn when to use Playwright storage state or persistent profiles, how to secure them, and how to reuse authenticated sessions reliably.
Event Handling and Promises in Browser Automation
Learn the reliable wait-before-action pattern for Playwright and Puppeteer events, promises, popups, requests, downloads, navigation, and failures.
What Is an API Proxy? How It Works and When to Use One
Learn how API proxies route, secure, transform, and observe requests, how they differ from gateways, and when adding one makes sense.
Stealth Techniques for Browser Automation: Capabilities and Limits
Learn what browser stealth can change, what modern bot detection still sees, and how to build reliable automation for authorized use.
Session Hijacking: Types, Attack Methods, and Countermeasures
Learn how session hijacking works, how attackers steal or fix session IDs, and how to prevent, detect, test, and respond to compromised sessions.
Building Real-Time Data Services with Browser Automation
Build a reliable browser-automation pipeline that captures live JavaScript data, validates events, and republishes them through APIs, WebSockets, or queues.
How to Build Browser Session Replay for Automation
Build browser session replay around the outcome you need: diagnose failures, preserve visual evidence, author tests, or reproduce execution.
What Browser Do Screenshot APIs Use to Capture Websites?
Most screenshot APIs run headless Chromium, but Playwright can use Firefox or WebKit. Learn how engines, versions, fonts and waits change pixels.
Automating the Web with Headless Browsers
Learn how headless browsers work, choose Playwright, Puppeteer or Selenium, and build reliable browser automation with runnable examples.
Caching Strategies for Screenshot and Browser APIs
Design cache layers for browser APIs and screenshots with correct freshness, privacy, readiness, invalidation, and cost controls.
Crawler APIs for Monitoring Website Changes
Learn how to build reliable website change monitoring with crawler APIs, snapshots, diffs, scheduling, alerts, and ScreenshotNeo captures.
The Art of Reverse Engineering Website APIs
Learn how to inspect a website’s browser requests, safely replay authorized calls, and document the contract in OpenAPI.
Webhooks for Screenshot and Image Generation APIs
Build reliable webhook handling for async screenshot and image generation jobs, with provider specific verification, retries, idempotency, and recovery.
How to Keep Puppeteer Browsers Alive with Reconnectable Sessions
Keep a Puppeteer browser running while workers disconnect, then reconnect safely with its WebSocket endpoint, lifecycle controls, diagnostics, and production patterns.
Building a Graphic Design Template Editor with a REST API
Learn how to model editable templates, design a versioned REST API, handle exports as jobs, and choose between building an editor and embedding one.
