Which Should You Pick?

The right choice between 11ty and SvelteKit depends on three things: your team's technical skills, your project timeline, and your long-term content strategy.

These platforms take fundamentally different approaches. 11ty is a ssg built with JavaScript (multiple template languages), while SvelteKit is a framework built with JavaScript/TypeScript (Svelte). That architectural difference shapes everything from daily content editing workflows to deployment and hosting costs. Both platforms require some technical comfort — consider which tech stack aligns better with your team's existing skills.

From a cost perspective, both platforms are open-source, so the real cost difference is hosting and operational overhead. Factor in plugin or extension costs, developer rates for each tech stack, and whether you need managed hosting or can self-host.

Whichever you choose, migrating between them is straightforward. LeaveWP supports migration between 60+ platforms, so you're never locked in regardless of which you pick today.
