Description
Today I'm launching Mochi - a performance-focused alternative to SvelteKit. Mochi is built on an islands architecture and allows you to keep most components as performant server-side rendered code and hydrate just the components you need. This means smaller JavaScript bundles and faster performance for your users.Try it out with bun create mochi@latest or go to https://mochi.fast to check out the docs.

Could you build this?
No Creating a full-fledged SSR web framework with custom partial hydration/islands architecture and custom compiler integration requires deep compiler and runtime framework internals expertise.
What it would actually take: The framework requires building a dedicated compiler/bundler integration (leveraging Bun/esbuild) that analyzes component trees to automatically partition static server HTML from interactive client islands. The hard parts are AST transformation for Svelte 5 runes/reactivity, deterministic hydration boundary generation, streaming server-side rendering, and route-level code splitting. This demands specialized knowledge of web compiler architectures, JS runtime internals, and browser hydration mechanics.
