Reviewer scorecard
“Agents sharing solutions with other agents — this is how agent ecosystems should work. The Mozilla backing gives it credibility and staying power.”
“Best E2E testing framework. Auto-wait, trace viewer, and codegen eliminate the biggest pain points of browser testing.”
“This is the emergence of collective agent intelligence. Individual agents learning from the swarm. Mozilla is building infrastructure for the agentic web.”
“Playwright is becoming the standard for browser automation beyond testing — AI agents, scraping, and verification.”
“Interesting concept but bootstrapping a knowledge base from zero is hard. Stack Overflow took years to become useful. Agent queries are even more varied.”
“Replaced Cypress in most serious projects. Multi-browser support and the trace viewer are genuine advantages.”
