Reviewer scorecard
“First-party SDK with excellent TypeScript support. Tool use and streaming work flawlessly. The agent loop is well-designed.”
“Playwright has surpassed Cypress in capabilities. Multi-browser, auto-waiting, and trace viewer are all better in Playwright.”
“Using the official SDK reduces risk of breaking changes. The agent patterns are production-tested by Anthropic themselves.”
“Was the best E2E framework but Playwright has taken the lead. The cloud pricing for CI is expensive.”
“Anthropic's approach to safe, capable agents sets the standard. The SDK makes best practices the default path.”
“The test runner UI and time-travel debugging are the most intuitive of any testing tool.”
