Browser Agent, Browser Protocol, or Automation Script?
A simple decision guide for choosing between Webwright, Agent Browser Protocol, browser-use, and plain browser automation.
Browser automation now has several layers. Picking the wrong layer can make a simple task too heavy or a risky task too loose.
Use Webwright when the browser task is long and decision-heavy. Use Agent Browser Protocol when browser access should become a reusable agent tool. Use browser-use when you want a practical browser agent library. Use a plain script when the page flow is stable and deterministic.
Decision table
| Need | Best fit |
|---|---|
| One stable workflow | Automation script |
| Agent makes decisions across pages | Browser agent framework |
| Multiple agents need browser access | Browser protocol or MCP tool |
| Researching long tasks | Webwright-style benchmark workflow |
Security baseline
Start with a non-production account, record actions, block irreversible steps, and require approval before sensitive forms, payments, or account changes.
Practical advice
Do not start by giving a browser agent full access. Start with one workflow, one success metric, and one recovery plan.
