WatchwrightBrowser tests you can watch, pause, fix and review

Playwright tests with their own server and web page, on your own computer or your own server.

Get started

Watchwright or Playwright Test?

End-to-end tests of your web app

Write tests in TypeScript in the Playwright style or in YAML, or record them by clicking through your site.

Writing a test pack

Compare setups

Run the same tests with different settings, such as a browser, a language or a feature flag, line the runs up side by side, and score them when a person judges the result.

Reviewing results

Watch a live site

Schedules start runs by themselves and alerts reach your phone or chat. The attempt that broke keeps its video, trace and log.

Schedules

Watch it

Every run streams a live picture of the browser to Watchwright's web page, with the current test, step and log.

Control it from the page

Start, pause, resume, retry, skip and stop runs, then review what each test saved, from screenshots and text to video and Playwright traces. Or schedule them, and get an alert when one fails.

Test any site

Write test packs for your own websites, as a folder with a pack file and test files in the familiar Playwright style.

Let your agents drive

Everything the page does is an API call. AI coding agents such as Claude Code, Codex or any MCP client get it through a CLI, an MCP server and an agent skill. Watchwright has no AI assistant of its own.

Built to grow

Every capability is a plugin on one core of browser sessions, jobs, events and actions. Testing comes first; scraping and crawling can follow without reworking the base.

Safe on your machine

On your computer the server listens on 127.0.0.1 and refuses requests from other web pages open in your browser. On a server, login with roles is always on.

Try it in one command: npx watchwright demo starts a run of the TodoMVC example pack against Playwright's public demo app and opens it.

Status: early. The run engine, test packs (in code or YAML), the live view, reviews, the editor, recording, schedules, alerts, secrets, saved sign-ins, the HTTP API, the command line, the MCP server and the agent skill work.
