Best forJavaScript dev teamsQA teams with coding skills
Who it's not forNon-technical buyers wanting no-code scrapingTeams without engineers . tests are code and break constantly
PrivacyGoogle-maintained open-source library; Snyk tracks known npm vulnerabilities.⁴Multiple public CVEs, mostly Selenium Grid; a critical flaw in an old Docker hub image and in-the-wild cryptomining abuse of exposed Grids.
Support qualityCommunity and GitHub issues only; no SLACommunity and sponsorship only; no vendor support
Public sentimentDeveloper chatter treats Puppeteer as a staple for Chrome automation, with gripes centered on Chrome-only limits and self-hosting overhead.⁸Users value its free flexibility but consistently flag coding demands, brittle tests, and heavy maintenance.13
Biggest gotchaPublicly exposed Puppeteer-rendering services are a known attack targetFree tool, expensive operation: you pay for Grid hosting, CI infrastructure, and engineers' time.15
