The right choice between Astro and SvelteKit depends on three things: your team's technical skills, your project timeline, and your long-term content strategy.
Both platforms sit in the same category — framework — so the deciding factors are ecosystem size, editorial workflow, and specific feature gaps. Astro uses JavaScript/TypeScript (framework-agnostic), while SvelteKit runs on JavaScript/TypeScript (Svelte). If your developers already know one of those stacks, lean toward that platform to reduce ramp-up time.
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.
