Reviewer scorecard
“Playwright has surpassed Cypress in capabilities. Multi-browser, auto-waiting, and trace viewer are all better in Playwright.”
“Real-time UI without writing JavaScript. The BEAM VM handles millions of concurrent connections effortlessly.”
“Was the best E2E framework but Playwright has taken the lead. The cloud pricing for CI is expensive.”
“LiveView proves server-rendered real-time UI is viable. For CRUD apps with real-time needs, it eliminates the SPA.”
“The test runner UI and time-travel debugging are the most intuitive of any testing tool.”
“Server-rendered real-time UI is the sleeper approach. LiveView, HTMX, and similar tools challenge SPA dominance.”
