Playwright CLI for agent-driven workflows: sessions, debugging, and CI Sharding

Playwright has excellent tooling around browser automation, but most of the ecosystem still treats it as a test framework. For teams running AI coding agents and automated browser workflows, there is a different set of requirements: browser automation ↓ session persistence across runs ↓ debuggable traces when things go wrong ↓ parallel execution across CI shards The Playwright CLI directly addresses these gaps. It ships as a standalone npm package and exposes every browser operation as a CLI command; open, click, type, snapshot - without requiring a Node.js script or test runner. npm package: @playwright/cli GitHub: https://github.com/microsoft/playwright-cli The current implementation focuses on: session persistence with named instances and portable state video and trace recording built into every session CI sharding for parallel execution at scale session persistence The default behaviour keeps browser state in memory. Cookies and localStorage are preserved between CLI calls within the session, but cleared when the browser closes. For repeatable workflows, that breaks down fast — logging into an application before every run wastes time and introduces flakiness. Named sessions let you run multiple browser instances simultaneously and address them by name: playwright-cli -s=admin open https://app.example.com/admin playwright-cli -s=checkout open https://app.example.com/checkout Each session is an isolated browser instance. An agent can orchestrate workflows across multiple authenticated contexts without state leaking between them. The goal is straightforward: the same CLI binary should be able to maintain independent browser contexts for parallel workflows without requiring environment-specific configuration. The critical piece for CI and agent reuse is state persistence: log in once playwright-cli -s=admin open https://app.example.com/login playwright-cli -s=admin fill "#username" "admin" playwright-cli -s=admin fill "#password" "$ADMIN_PASS" playwright-cli -s=admi
