Microsoft Webwright

Webwright là browser agent framework: thay vì predict discrete actions, agent viết Python/Playwright script tự do — script reusable, testable, maintainable như code thật.

Install

pip install -e .
playwright install chromium

Usage

python -m webwright.run.cli \
    -c base.yaml -c model_openai.yaml \
    -t "Book a flight from Hanoi to HCM City, cheapest option" \
    --start-url https://www.google.com/travel/flights \
    -o outputs/flight-booking

Config

# base.yaml
workspace_dir: ./workspace
max_steps: 50
screenshot_on_failure: true

# model_anthropic.yaml
model:
  provider: anthropic
  name: claude-sonnet-4-6
  api_key: ${ANTHROPIC_API_KEY}

Core Pattern — Agent Loop

Task → Launch browser → Observe (screenshot + DOM)
     → Write Playwright script → Execute → Inspect failure?
     → Screenshot + re-observe → Refine script → Loop
     → Final artifact = reusable Python script + logs

Slash Commands (Claude Code plugin)

/plugin install webwright@webwright

/webwright:run    -- single-shot task
/webwright:craft  -- tạo reusable CLI tool từ task description

Điểm mạnh

• Script output là code thật — không phải click trace
• 86.7% Online-Mind2Web SOTA (2026)
• ~1.5k lines core — đọc hiểu dễ
• Support OpenAI, Anthropic, OpenRouter
• Trajectory + screenshots lưu disk để debug

Khi nào dùng

• Automation web phức tạp (multi-step, conditional logic)
• Cần script có thể chạy lại, không phải one-off recording
• RPA-style workflow với LLM decision layer
• Web scraping có login, dynamic content
