Toasted golden, schmeared with insight. Top of the rack.
Summary
The article details a technical team's decision to migrate from Playwright to Chrome DevTools Protocol (CDP) for browser automation. The author explains that while Playwright and Puppeteer are excellent for creating readable QA tests and automation scripts, they can obscure important browser-level details. By switching to raw CDP, the team achieved significant performance improvements in element extraction, screenshots, and default actions, gaining finer-grained control over browser operations.
Key quotes
· 3 pulledPlaywright and Puppeteer are great for making QA tests and automation scripts short and readable, but as AI browser companies have been learning the hard way over the last year, sometimes these adapters obscure important details about the underlying browsers.
We decided to peek behind the curtain and figure out what the browser was really doing, and it made us decide to drop playwright entirely and just speak the browser's native tongue: CDP.
By switching to raw CDP we've massively increased the speed of element extraction, screenshots, and all our default actions.
