Updated: Oct 2026; last repo commit

Ask it to check a form, a user flow or a layout. The assistant drives a browser with Playwright, verifies elements and text, captures screenshots and reads console logs. SKILL.md says to use the Playwright MCP Server if possible, and to fall back to Node.js code if it is unavailable.

It needs Node.js and an app running locally or at a URL you can reach. It bundles one small JavaScript helper file for waiting, console capture and screenshots.

Good for

Front-end developers checking a form or flow after a change
Anyone debugging UI behavior who wants screenshots and console logs
Teams checking a layout at several viewport sizes

Install webapp-testing

Claude Code

1
Download the skill folder from https://github.com/github/awesome-copilot/tree/HEAD/skills/webapp-testing.
2
Put it at ~/.claude/skills/webapp-testing/ so that SKILL.md sits directly inside.
3
Start a new session; the skill loads when its description matches the task.

Requires Node.js.

SKILL.md lists Node.js as a prerequisite and says Playwright is installed automatically if it is missing. It drives a browser against a web app that runs on your own machine, so this page lists no Claude app upload. Use Claude Code or Codex.

Built from the package data we hold. Not yet tested by us.

Watch out for

It installs Playwright if it is missing
The prerequisites say Playwright will be installed automatically if not present. Approve the install command, and expect a package download. github.com
It drives a real browser against your app
The examples navigate, fill forms and click submit buttons on a local app. Point it at a test environment, not production. github.com
It saves screenshots
The helper file's captureScreenshot writes a timestamped full-page PNG in the current folder. Screenshots can show data from your app. github.com

Questions

What does this webapp-testing skill do?

It makes your assistant test a local web application with Playwright. It can click through flows, check what is on the page, capture screenshots and read browser console logs.

How do I install it?

Use the install box at the top of this page. You also need Node.js and a running app. SKILL.md says Playwright is installed automatically if it is missing.

Does it work in the Claude app or claude.ai?

This page lists no Claude app upload. SKILL.md needs Node.js and a web app you can reach, and it drives a browser, so the install box lists Claude Code, Codex and the skills CLI.

Does it need the Playwright MCP Server?

No. SKILL.md says to use the Playwright MCP Server if possible, and to run the code in a local Node.js environment with Playwright if it is not available.

Is it safe?

It drives a real browser against your app, can install Playwright and saves screenshots to the current folder. Our advice: point it at a test environment with test accounts.

What are its limits?

SKILL.md lists three: it needs Node.js, it cannot test native mobile apps, and it may have trouble with complex authentication flows or frameworks that need special configuration.

How is it different from Anthropic's webapp-testing skill?

Both share the same name and description. This GitHub version uses JavaScript Playwright and prefers the Playwright MCP Server, while Anthropic's SKILL.md tells the assistant to write Python Playwright scripts and run them with its with_server.py helper.
