playwright-cli

Playwright-cli is a powerful command-line interface designed to streamline browser automation for coding agents and developers. Unlike standard automation libraries that can overwhelm LLM context windows with verbose accessibility trees, this CLI is optimized for token efficiency. It provides a specialized set of commands that allow agents to interact with web pages, perform UI testing, and manage browser states without forcing entire DOM snapshots into the prompt. This makes it an ideal choice for high-throughput automation, self-healing test maintenance, and complex agentic loops where context management is critical.

The tool covers the full spectrum of browser interaction, including navigation, element manipulation (clicking, typing, drag-and-drop, filling forms), and network interception. It features advanced capabilities like session persistence via browser profiles, request mocking for API testing, geolocation control, and integration with visual dashboards for monitoring background tasks. Users can execute arbitrary Playwright code snippets for custom logic, capture snapshots, take screenshots, or generate PDFs, all while maintaining the speed and low overhead of a terminal-based workflow.

• Perform granular browser actions: goto, click, type, fill, scroll, hover, and drag-and-drop elements.

• Manage browser context: handle tabs, persistent storage, cookies, and local/session storage across multiple sessions.

• Sophisticated network control: route traffic to mock APIs, modify headers, block specific assets, and simulate network failures or latency.

• Advanced debugging and observability: launch headed modes, run a visual dashboard to inspect live browser sessions, capture traces, and record video chapters.

• Development-focused workflow: generate Playwright locators automatically, inspect DOM attributes via eval, and debug tests using CLI-based attachment protocols.

• Intended for developers, QA engineers, and autonomous coding agents like Claude Code or GitHub Copilot.

• Requires Node.js 18 or newer; install globally via npm and enable skill integration for seamless agent operation.

• Operates as a stateless or persistent browser session manager; default headless execution can be toggled to headed mode for debugging.

• Best practices include using the --raw flag to pipe output into Unix utilities like jq, or using --json for structured data processing.

• Effectively bridges the gap between manual exploratory testing and automated, script-based regression suites.
