What happened
SvelteKit 3.0's release candidate promotes 'remote functions' from experimental status (introduced in 2.27) to equal footing with traditional load functions, enabling type-safe RPCs directly inside individual page components without full page refreshes. A cited benchmark shows SvelteKit's SSR returns HTML payloads three times smaller than Next.js for an equivalent product page.
Why it matters
If you're choosing a full-stack JS framework for a new project, SvelteKit 3's remote functions eliminate the boilerplate of manual data-fetching hacks while preserving end-to-end type safety — a concrete DX advantage over Next.js patterns. The 3x smaller SSR payload benchmark is worth validating against your own pages if performance is a selection criterion.
Discussion angle
Compare the remote functions model against Next.js Server Actions and tRPC — is type-safe RPC-in-components enough to justify migrating, or is this still too experimental to bet on for production?
