+# Browser Session Management
+
+Run multiple isolated browser sessions concurrently with state persistence.
+
+## Named Browser Sessions
+
+Use `-s` flag to isolate browser contexts:
+
+```bash
+# Browser 1: Authentication flow
+playwright-cli -s=auth open https://app.example.com/login
+
+# Browser 2: Public browsing (separate cookies, storage)
+playwright-cli -s=public open https://example.com
+
+# Commands are isolated by browser session
+playwright-cli -s=auth fill e1 "user@example.com"
+playwright-cli -s=public snapshot
+```
+
+## Browser Session Isolation Properties
+
+Each browser session has independent:
+- Cookies
+- LocalStorage / SessionStorage
+- IndexedDB
+- Cache
+- Browsing history
+- Open tabs
+
+## Browser Session Commands
+
+```bash
+# List all browser sessions
+playwright-cli list
+
+# Stop a browser session (close the browser)
+playwright-cli close                # stop the default browser
+playwright-cli -s=mysession close   # stop a named browser
+
+# Stop all browser sessions
+playwright-cli close-all
+
+# Forcefully kill all daemon processes (for stale/zombie processes)
+playwright-cli kill-all
+
+# Delete browser session user data (profile directory)
+playwright-cli delete-data                # delete default browser data
+playwright-cli -s=mysession delete-data   # delete named browser data
+```
+
+## Environment Variable
+
+Set a default browser session name via environment variable:
+
+```bash
+export PLAYWRIGHT_CLI_SESSION="mysession"
+playwright-cli open example.com  # Uses "mysession" automatically
+```
+
+## Common Patterns
+
+### Concurrent Scraping
+
+```bash
+#!/bin/bash
+# Scrape multiple sites concurrently
+
+# Start all browsers
+playwright-cli -s=site1 open https://site1.com &
+playwright-cli -s=site2 open https://site2.com &
+playwright-cli -s=site3 open https://site3.com &
+wait
+
+# Take snapshots from each
+playwright-cli -s=site1 snapshot
+playwright-cli -s=site2 snapshot
+playwright-cli -s=site3 snapshot
+
+# Cleanup
+playwright-cli close-all
+```
+
+### A/B Testing Sessions
+
+```bash
+# Test different user experiences
+playwright-cli -s=variant-a open "https://app.com?variant=a"
+playwright-cli -s=variant-b open "https://app.com?variant=b"
+
+# Compare
+playwright-cli -s=variant-a screenshot
+playwright-cli -s=variant-b screenshot
+```
+
+### Persistent Profile
+
+By default, browser profile is kept in memory only. Use `--persistent` flag on `open` to persist the browser profile to disk:
+
+```bash
+# Use persistent profile (auto-generated location)
+playwright-cli open https://example.com --persistent
+
+# Use persistent profile with custom directory
+playwright-cli open https://example.com --profile=/path/to/profile
+```
+
+## Attaching to a Running Browser
+
+Use `attach` to connect to a browser that is already running, instead of launching a new one.
+
+### Attach by channel name
+
+Connect to a running Chrome or Edge instance by its channel name. The browser must have remote debugging enabled — navigate to `chrome://inspect/#remote-debugging` in the target browser and check "Allow remote debugging for this browser instance".
+
+```bash
+# Attach to Chrome
+playwright-cli attach --cdp=chrome
+
+# Attach to Chrome Canary
+playwright-cli attach --cdp=chrome-canary
+
+# Attach to Microsoft Edge
+playwright-cli attach --cdp=msedge
+
+# Attach to Edge Dev
+playwright-cli attach --cdp=msedge-dev
+```
+
+Supported channels: `chrome`, `chrome-beta`, `chrome-dev`, `chrome-canary`, `msedge`, `msedge-beta`, `msedge-dev`, `msedge-canary`.
+
+When `--session` is not provided, the session is named after the channel (e.g. `--cdp=msedge` creates a session called `msedge`), so parallel attaches to Chrome and Edge don't collide on `default`. Pass `--session=<name>` to override.
+
+### Attach via CDP endpoint
+
+Connect to a browser that exposes a Chrome DevTools Protocol endpoint:
+
+```bash
+playwright-cli attach --cdp=http://localhost:9222
+```
+
+### Attach via browser extension
+
+Connect to a browser with the Playwright extension installed:
+
+```bash
+playwright-cli attach --extension
+```
+
+### Detach
+
+Tear down an attached session without affecting the external browser:
+
+```bash
+# Detach the default attached session
+playwright-cli detach
+
+# Detach a specific attached session
+playwright-cli -s=msedge detach
+```
+
+`detach` only works on sessions created via `attach`. For sessions created via `open`, use `close`.
+
+## Default Browser Session
+
+When `-s` is omitted, commands use the default browser session:
+
+```bash
+# These use the same default browser session
+playwright-cli open https://example.com
+playwright-cli snapshot
+playwright-cli close  # Stops default browser
+```
+
+## Browser Session Configuration
+
+Configure a browser session with specific settings when opening:
+
+```bash
+# Open with config file
+playwright-cli open https://example.com --config=.playwright/my-cli.json
+
+# Open with specific browser
+playwright-cli open https://example.com --browser=firefox
+
+# Open in headed mode
+playwright-cli open https://example.com --headed
+
+# Open with persistent profile
+playwright-cli open https://example.com --persistent
+```
+
+## Best Practices
+
+### 1. Name Browser Sessions Semantically
+
+```bash
+# GOOD: Clear purpose
+playwright-cli -s=github-auth open https://github.com
+playwright-cli -s=docs-scrape open https://docs.example.com
+
+# AVOID: Generic names
+playwright-cli -s=s1 open https://github.com
+```
+
+### 2. Always Clean Up
+
+```bash
+# Stop browsers when done
+playwright-cli -s=auth close
+playwright-cli -s=scrape close
+
+# Or stop all at once
+playwright-cli close-all
+
+# If browsers become unresponsive or zombie processes remain
+playwright-cli kill-all
+```
+
+### 3. Delete Stale Browser Data
+
+```bash
+# Remove old browser data to free disk space
+playwright-cli -s=oldsession delete-data
+```
