When to choose HTTP/3

Choose HTTP/3 when your primary concern is server response time and performance. Its audit data shows consistent strength in these areas across the sampled sites.

When to choose PWA

PWA doesn't clearly lead HTTP/3 in any category on the sampled sites — pick it based on developer experience, ecosystem, or existing team skills rather than the audit scores.

How this comparison was built

Scores are medians across 2227 audited HTTP/3 sites and 153 audited PWA sites in the BeaverCheck database. Every audit runs the same 100+ checks — Lighthouse performance, security headers, accessibility, SEO, server response time — against a real URL. No vendor input, no sponsorship, no affiliate links.

Which has better security, HTTP/3 or PWA?
HTTP/3 sites score higher on security analysis (74 vs 72 on average).
Which has better accessibility, HTTP/3 or PWA?
Accessibility scores measured by Lighthouse WCAG 2.1 checks favor HTTP/3 (90 vs 90). Both technologies can be made fully accessible with care — the difference reflects common patterns in the sampled sites, not inherent platform limits.
Which is better for SEO, HTTP/3 or PWA?
HTTP/3 sites score higher on Lighthouse SEO signals (92 vs 92 on average), which cover meta tags, crawlability, mobile friendliness, and structured data. Content strategy and backlinks still matter more than platform choice for ranking.
Which has faster server response (TTFB), HTTP/3 or PWA?
HTTP/3 sites show lower Time to First Byte (401 ms vs 435 ms on average). TTFB depends heavily on hosting and CDN setup rather than the technology itself, but the sampled sites suggest a meaningful difference in common deployment patterns.
