# chrome-devtools vs playwright-cli

Pick chrome-devtools when the question is why a page behaves badly: it drives a real Chrome and adds focused skills for accessibility debugging, memory leaks and LCP performance. Pick playwright-cli when the goal is a repeatable test or automation: navigation, assertions, request mocking, tracing, video and test generation against an existing Playwright suite. Both are first-party and both drive a local browser, so the choice is diagnosis versus automation, not vendor preference.

## Pick chrome-devtools when

A page is slow, inaccessible, leaking memory, or failing in a way you cannot reproduce in a test — and you need the browser’s own instrumentation.

## Pick playwright-cli when

You want a test that runs in CI, or automation that repeats reliably: assertions, mocked requests, traces to inspect after a failure.

## Side by side

| | chrome-devtools | playwright-cli |
| --- | --- | --- |
| Primary job | Inspect and diagnose a live page | Automate and assert against a page |
| Specialised skills | a11y debugging, memory-leak debugging, LCP optimisation, troubleshooting | Test generation, tracing, component testing |
| Fits an existing suite | No — it is a debugging surface | Yes — built around Playwright projects |
| Install model | Plugin marketplace, ships an MCP server | playwright-cli install --skills |
| Browser | Chrome only | Chromium, Firefox, WebKit |
| Blocked or anti-bot targets | Not its job | Not its job — its own entry says so |
| Provenance | Verified (Chrome DevTools, Google) | Verified (Microsoft) |

## Bottom line

Install both if you own a web app: they cover the two halves of the same loop. playwright-cli catches the regression, chrome-devtools explains it. If you install only one, pick by which failure you have more of — flaky behaviour nobody has characterised (chrome-devtools) or behaviour that works today and must keep working (playwright-cli). Neither is the right answer for scraping sites that fight back; both entries say so, and the proxy-based skills exist for that.

## Common questions

**Is chrome-devtools a replacement for Playwright?**

No. It has no test runner, no assertions and no CI story — it is the browser’s instrumentation exposed to an agent. Playwright remains the tool for tests that must pass repeatedly; DevTools is how you work out why one stopped passing.

**Do they conflict if both are installed?**

No. They load on different triggers — a debugging or performance question reaches for one, a test or automation task the other — and both drive a local browser rather than a shared hosted session.

**Which handles cross-browser work?**

playwright-cli. Chrome DevTools is Chrome-only by definition. If a bug is Safari- or Firefox-specific, Playwright is the only one of the two that can reproduce it.
