Polypane
A developer-focused browser for multi-view responsive design, accessibility audits, and performance insights—all side by side.
We use Polypane to validate layouts across breakpoints simultaneously, run a11y checks, visualize landmarks/headings, and preview meta/OG cards efficiently.
How We Use It
- Simultaneous responsive design testing
- Accessibility audits and landmark visualization
- Performance profiling and meta tag preview
Monitoring & Testing
Why this matters: Observability and tests catch regressions early, reduce MTTR, and enable confident, frequent releases. We ship with confidence by instrumenting apps end-to-end: unit and integration tests, accessibility checks, and production observability. Our approach emphasizes fast feedback loops, clear failure signals, and actionable telemetry. Preferred defaults: Sentry for errors/perf, Playwright for E2E, Vitest or Bun Test for unit, OpenTelemetry for tracing, Lighthouse CI for budgets.
