Everything you need to know about browser automation
Guides, insights, comparisons, and reviews across Playwright MCP, Browser Use, Chrome DevTools MCP, coding agents, and the browsers they drive.
GuidesWhy computer use isn't working: debugging guide
Start with the error you can see. Check permissions, app approvals, helper sessions, and window attachment, then retry one small step.
GuidesFixing scraper breakage when websites change
A scraper can return zero rows and still report success. Four page versions show how extraction layers and field checks catch that failure.
ComparisonsPlaywright MCP vs Browser Use: Which Does Your Agent Need
The most common mistake in this comparison is treating the two as rivals in one category. One is a protocol tool your coding agent drives step by step; the other is an autonomous framework with its own loop. Pick by task shape.
GuidesClaude Code Browser Login: How to Automate Sites Behind Auth
The agent's browser isn't signed in to anything; that's the whole problem. Three real routes with steps and risk profiles, plus practical guidance for CAPTCHAs, OAuth loops, session expiry, 2FA, and scheduled runs.
GuidesWhy AI Agents Can't Click or Type in Your Browser
If ChatGPT can describe the page but will not click or type, treat it as a control handshake, not a broken Chrome install. Check the native host, profile, and site allowlist, then prove a click on a public page.
GuidesPlaywright Test Failure States: Handling API 500s
A 500 is not one test outcome. Mock it when you own the error UI, fail immediately on a live contract, and never retry a deterministic server error until green.
GuidesSet Up a Remote Browser Workspace with Codex and Docker
Codex Remote is a phone talking to your Mac. Docker Sandboxes run Codex in a sandbox. Playwright Docker is the browser you can view over noVNC. Assemble them on purpose.
GuidesBrowser Automation That Survives UI Changes
Durable browser automation needs more than stable selectors. The right choice depends on whether the workflow is a maintained regression path or changing live work.
GuidesPersistent Browser Sessions Across Agent Runs
A session that survives one run and dies on the next is the most common agent failure that looks like an application bug. Here is the full lifecycle: how to establish, preserve, verify, isolate, expire, and recover a browser session, with the profile-lock and session-cookie traps named.
