Reviewer scorecard
“Playwright has surpassed Cypress in capabilities. Multi-browser, auto-waiting, and trace viewer are all better in Playwright.”
“Guaranteed valid JSON from LLMs — no retry loops needed. The FSM approach is mathematically elegant and reliable.”
“Was the best E2E framework but Playwright has taken the lead. The cloud pricing for CI is expensive.”
“If you need structured outputs from open models, Outlines is the correct solution. Not a hack, but a proper constraint system.”
“The test runner UI and time-travel debugging are the most intuitive of any testing tool.”
“Constrained generation will be built into every inference engine. Outlines pioneered the approach.”
