Browser Automation Tools: Playwright vs Puppeteer vs Selenium

Someone asked me about this last week and I realized I should just write it down properly instead of explaining it in DMs for the hundredth time.

Step-by-step

I am going to walk through this exactly as I did it, including the parts where I got confused and had to backtrack. Because that is the reality of working with new tools.

Prerequisites: a working setup of whatever platform you are using (I use OpenClaw but the concepts apply broadly), about 30 minutes of uninterrupted time, and maybe a second monitor for the docs.

The messy middle

Getting started is easy. Getting to production-ready is hard. The difference is in the details that nobody blogs about because they are boring. But boring is what keeps systems running at 3 AM.

The gotchas

Three things that will trip you up if you are not ready for them. First: permissions. Always check permissions first when something does not work. Second: caching. Clear it. Clear it again. OK now it works. Third: documentation lag. The docs are often one version behind. When in doubt, check the source code.

I will update this article as things change — and in this space, things change fast. Bookmark it and check back. More related content at clawseo.net, clawgo.net. Official references: Anthropic Docs, Redis Documentation.
