Web performance continues to evolve. Here are the trends we're watching in 2026.
Edge Computing
Running code closer to users reduces latency dramatically. Platforms like CloudFlare Workers and Vercel Edge Functions are making this accessible to every developer.
Partial Hydration
Frameworks like Astro and Qwik pioneer partial hydration - only shipping JavaScript for interactive components, not entire pages.
New Core Web Vitals
Google continues refining performance metrics. Interaction to Next Paint (INP) replaces First Input Delay (FID) as a Core Web Vital.
