Playwright
Playwright is an open-source end-to-end automated testing framework developed by Microsoft, primarily used for browser automation testing of web applications. It supports mainstream browsers including Chromium, Firefox, and WebKit, providing cross-browser and cross-platform testing capabilities, with support for multiple programming languages such as JavaScript, TypeScript, Python, and Java. Playwright features auto-waiting, network interception, screenshot and video recording, and is widely used in front-end testing, UI testing, and browser automation scenarios.
Core Facts

Browser Use offers two page-understanding modes: DOM mode and visual mode.
Browser Use drives browser operations through Playwright at the underlying level, using large language models to understand user intent and incrementally generate execution actions.
Timeline (last 90 days)
Gologin Cloud Browser supports the two mainstream browser automation frameworks Playwright and Puppeteer via WebSocket.
Lauren Tan extracts the deterministic parts into custom CLIs (such as scripts that interact with Playwright and the Chrome DevTools Protocol) to avoid each Agent repeatedly building verification scripts.
The technical paths for implementing cross-app automated operations on mobile typically include official API integration, Accessibility Service, and cloud-based automation scripts (such as Playwright and Selenium).
The proof command in the talk is essentially a Playwright script: confirm the waitlist is empty, fill in an email, click the button, assert that the status element contains "wait listed", and check whether the inner text contains that email.
General web tasks refer to online operations that do not rely on a specific website's API and can be completed solely by simulating human browsing behavior (such as clicking, scrolling, and filling out forms), typically implemented through browser automation frameworks such as Playwright and Puppeteer.
Computer Use no longer relies only on a single action loop; instead, it directly writes JavaScript code to execute multi-step operations in batches within the browser environment, and fuses multiple modalities of information such as screenshots, the accessibility tree, and Playwright.
CDP (Chrome DevTools Protocol) is the low-level debugging and automation interface exposed by the Chromium core, and both Puppeteer and Playwright use it as their primary communication foundation.
Current mainstream agent implementation approaches include browser automation (such as Playwright), desktop control (simulating mouse and keyboard), and screen understanding (OCR, visual localization).
The project configured GitHub Actions early on, running Playwright tests and generating full-site screenshots on every PR, accumulating 350 screenshots so far.
In most modern web application testing, Playwright is a better choice than Selenium, but Selenium still has its value in special business scenarios.
