DECISION GUIDE
When to pick each, and when to skip both.
Three plain-English paths: the case for Microsoft Playwright, the case for Cypress, and the free bring-your-own-key route that avoids seat fees entirely.
When to Pick Microsoft Playwright
99.8 / 100- 98,282+ GitHub stars under Apache-2.0 supporting Chromium, WebKit, and Firefox out of the box with 100% identical APIs
- Native multi-tab, multi-window, and multi-origin iframe testing with automatic waiting on DOM elements and network calls
- Cuts commercial BrowserStack and Sauce Labs cloud grid invoices by 95.8% ($120/mo self-hosted spot compute vs $2,850/mo SaaS)
When to Pick Cypress
97.9 / 100- 51,011+ GitHub stars under MIT engineered specifically for rapid developer feedback and interactive in-browser testing
- Visual time-travel debugger allows stepping through DOM snapshots and network requests in real time
- Unified component and end-to-end testing with extensive community plugin ecosystem and TypeScript support
When to Self-Host in Docker / K8s
Docker / Helm HA- $0 SaaS Usage / Per-Node Tax: Run on $18-$45/mo cloud VMs or bare-metal Kubernetes nodes with flat, predictable monthly compute.
- 100% VPC Data Sovereignty: Keep production telemetry, secrets, and customer traffic inside your own private network.
- Production HA Spec Included: Deploy with pre-tuned
docker-compose.prod.yml+helm-values.prod.yamlhealthchecks and resource limits.
