The hypermedia approach achieves a Lighthouse mobile score of 100 vs 54, Time to Interactive of 1.1s vs 8.2s, zero total blocking time vs 780ms, and transfers 26× less data. JavaScript bundle size is 80× smaller (13.5 KB vs 1.1 MB). During AI streaming, hypermedia uses 4.2× less JS execution time and completes 37% faster overall. SSE compression via Brotli on a persistent connection achieves a 58.5× ratio over 10 turns, transferring half the data despite a naïve implementation that re-streams full HTML fragments per token. Operationally, the hypermedia stack has 11.6× fewer production dependencies, no build step, and can run on a $20/year VPS. The post concludes with a decision framework for when each architecture is appropriate. ## Full article daily.dev links to this article rather than hosting it.
