Remix vs SvelteKit: Complete Comparison Guide
Compare Remix and SvelteKit on architecture, bundle size, developer experience, and performance. Discover which full-stack framework best fits your project.
Remix
A full-stack React framework that puts web standards at the center. Remix uses loaders and actions for data fetching, provides excellent form handling, and is designed for progressive enhancement. It is backed by Shopify and the React Router team.
SvelteKit
The official application framework for Svelte. SvelteKit combines Svelte's compiler approach with server-side rendering, routing, and data loading. Because Svelte compiles to vanilla JavaScript, bundles are smaller and runtime overhead is minimal.
Comparison table
| Feature | Remix | SvelteKit |
|---|---|---|
| UI library | Built on React — benefits from the full React ecosystem | Built on Svelte — compiler approach without virtual DOM |
| Bundle size | Larger due to React runtime (approximately 40kb+ baseline) | Smaller thanks to compile-time optimization (no runtime overhead) |
| Data loading | Loaders (GET) and actions (mutations) per route segment | Load functions on server and client with automatic type inference |
| Forms | Progressive forms with native HTML forms and actions | Form actions with progressive enhancement and server-side validation |
| Deployment | Platform-agnostic via adapters (Node, Cloudflare, Deno) | Platform-agnostic via adapters (Node, Vercel, Cloudflare, static) |
Verdict
Remix and SvelteKit are both excellent full-stack frameworks with a similar philosophy around web standards and progressive enhancement. The key difference is the underlying UI library: React versus Svelte. Remix benefits from the massive React ecosystem while SvelteKit offers smaller bundles and a simpler developer experience. If your team knows React, Remix is the logical step. If you are open to Svelte, SvelteKit provides technical advantages in bundle size and performance.
Our recommendation
At MG Software, we typically choose Next.js over Remix when working within the React ecosystem due to its broader feature set. However, we recognize that SvelteKit has impressive technical merits, especially in bundle size and developer experience. For clients seeking a lightweight alternative outside the React ecosystem, SvelteKit is a strong candidate. Our recommendation depends on team expertise and project requirements.
