Comparing playwright with agent-browser - **Playwright** = a **browser automation library** (code-first). - **Agent-browser** = an **AI-driven browser operator** (goal-first). What’s different: - **How you control it** - Playwright: you write explicit steps (`goto`, `click`, `fill`…) - Agent-browser: you give intent (“book this flight”, “find cheapest plan”), agent decides steps - **Determinism** - Playwright: highly deterministic/reproducible - Agent-browser: more adaptive, but less predictable run-to-run - **Best for** - Playwright: tests, stable workflows, scraping with known structure - Agent-browser: messy UIs, exploratory tasks, semi-autonomous ops - **Debugging** - Playwright: straightforward traces and exact failing step - Agent-browser: harder to debug because planning/reasoning layer is involved - **Cost/latency** - Playwright: generally faster/cheaper (no LLM loop) - Agent-browser: slower/costlier, trades that for flexibility
