What is Playwright?
Playwright is Microsoft's open-source automation framework for Chromium, Firefox, and WebKit, with first-class bindings for TypeScript, Python, Java, and .NET. Its test runner, auto-waiting, trace viewer, and CI integration are the strongest in the category, and for committed, deterministic end-to-end test suites it's the tool to beat. Microsoft has also started shipping playwright-cli, a token-conscious companion CLI from the Playwright team for coding agents like Claude Code and Copilot. This page is about the core framework and its scripting and CLI workflows; Playwright MCP, the separate agent-facing MCP server, has its own comparison page. Developers picking an agent-driven approach also weigh Browser Use vs Playwright and Stagehand vs Playwright, since all three show up in most LLM-driven browsing stacks.
Is ego(lite) a good Playwright alternative?
For AI-agent-driven browser work, yes: no scripts, real logins, parallel Spaces, making it one of the few Playwright alternatives built specifically for agents rather than more scripting. For committed end-to-end test suites in CI, no. Playwright's test runner, tracing, and cross-browser coverage are genuinely excellent, and you should keep using them. The honest split: Playwright for tests you commit, ego(lite) for tasks you delegate.
How was the ego(lite) vs Playwright benchmark run?
Both ran the same 31 complex real-world browser automation tasks on live websites, driven by the same pi agent with the same model (gpt-5.6-sol, thinking effort max) and graded by the same judge against per-task rubrics; every score covers all 31 tasks. Playwright entered through playwright-cli, the companion CLI the Playwright team ships for coding agents, which is the strongest agent-facing way to run it today. ego(lite) finished 93.5% of tasks perfectly at $1.75 per completed task, 63% faster on average task time; agent-driven Playwright finished 71% at $4.82. The harness, the tasks, the rubrics, and the raw results are open source in the ego-browser-benchmark-framework repository on GitHub, so every number can be audited or reproduced.
Playwright vs Puppeteer vs Selenium: which should I use?
All three are script-first frameworks, whether you search it as playwright vs puppeteer or puppeteer vs playwright. Playwright wins for new test suites: fastest runner, auto-waiting, TS/Python/Java/.NET, all three engines. Puppeteer wins when you're Chrome-only in Node and want a lean DevTools-level API. Selenium wins where the W3C WebDriver standard, broad language bindings, or an existing enterprise Grid matter. ego(lite) fills a different role: an AI agent does the browsing instead of a script, with no code to maintain and your real logged-in profile already attached.
Playwright vs Selenium: pros and cons?
Selenium vs Playwright comes down to trade-offs on both sides. Playwright: faster execution, built-in auto-waiting, a modern test runner, and tooling like trace viewer and codegen; the trade-off is a younger ecosystem. Selenium: the W3C WebDriver standard, the widest language and legacy-browser coverage, and two decades of enterprise adoption; the trade-off is more verbose code and more explicit wait management. If you're choosing a test framework today, most teams pick Playwright. If the work is agent-driven rather than scripted, see how ego(lite) compares to Selenium on our Selenium page.
What about Playwright MCP or playwright-cli for AI agents?
Both wrap a fresh Playwright browser for agent use, and both still run one command per action in a blank profile: Playwright MCP as MCP tool calls, playwright-cli as CLI invocations. ego(lite) instead batches multiple actions in JavaScript per turn, reads pages as compressed Snapshots, and starts from your real logged-in Chrome profile. Across those 31 live-site jobs that difference measures out to 93.5% of tasks perfect against 71%, at $1.75 per completed task against $4.82 and 63% faster on average task time, with playwright-cli as the Playwright entrant. Full breakdown on the ego(lite) vs Playwright MCP page.
Can Playwright use my existing Chrome logins?
Partially. You can save storageState after a scripted login, or launch a persistent context pointed at a Chrome profile directory, but sessions expire, 2FA and SSO interrupt scripted logins, and a profile can't be shared with a running Chrome. ego(lite) imports your profile once, and the agent inherits real login state from then on.
Is ego(lite) free?
Yes. Free, no subscription, data stored locally. The ego-browser shell your agent connects through is MIT-licensed open source.
Why are Playwright tests flaky in CI, and how do I fix them?
CI flake usually comes from shared state, unstable selectors, race conditions, resource pressure, or a test that assumes a fixed delay. Use isolated fixtures, locator-based assertions, waits for meaningful application state, bounded retries for diagnosis, and trace artifacts. ego(lite) is not a CI test-runner replacement: its visible Spaces help an agent investigate an interactive failure, while Playwright remains the right choice for committed deterministic suites.
Can ego(lite) or Playwright bypass Cloudflare, CAPTCHA, or Akamai?
No tool can guarantee that, and this page does not provide bypass instructions. A block is an access-control decision: respect the site's terms, robots and rate limits, use an official API or licensed feed, request permission, or stop. ego(lite) can use your own authorized browser session for content you can already see, but a real Chrome profile, residential IP, stealth plugin, or mouse simulation is not a promise of access and must not be used for ban evasion.
Is there a Playwright alternative with fewer brittle selectors?
For interactive, agent-driven work, ego(lite) lets the agent read the current page and choose an action instead of maintaining a generated selector for every one-off task. That reduces script maintenance, but it does not make a changing site magically stable: keep source-linked results, verify important fields, and retain Playwright for assertions and repeatable CI coverage. For Playwright itself, prefer roles, labels, test IDs, and stable application contracts over generated CSS classes.
Can an AI agent write and fix E2E tests in plain English?
An agent can turn a plain-English scenario into Playwright code, run the suite, inspect a trace, and propose or apply a fix in a controlled branch. It still needs a clear assertion contract, test data, and human review: an agent can make a test green by weakening an assertion or masking a product bug. ego(lite) is useful for exploring a flow in a real session; promote verified behavior into committed Playwright tests when it must run in CI.
How should Playwright alternatives handle third-party iframes and dynamic content?
Treat an iframe as a separate browsing context and wait for the frame or application state that proves it is ready; do not rely on arbitrary sleeps. For Stripe-like third-party checkout, use the provider's supported test mode and stable labels, and keep secrets out of fixtures. An agent can inspect a live frame and recover from a changed layout, but it cannot remove cross-origin restrictions or guarantee that a provider's UI will remain available.
