This is the most common reason teams migrate away from TYPO3. SvelteKit eliminates this issue entirely.

Extension ecosystem is smaller and less standardized
Modern architectures like SvelteKit are designed to avoid this from the ground up.

A detailed breakdown of how your TYPO3 content maps to SvelteKit
What may need manual attention
Custom server-side logic, third-party integrations, and platform-specific plugins will need equivalent solutions in SvelteKit. The core content (text, images, metadata) transfers cleanly.
Migrate your content in three simple steps
Enter your TYPO3 site URL — LeaveWP connects automatically.
Select SvelteKit as destination and choose content options.
Download your migrated content or preview it in your browser.
Migrating from TYPO3 to SvelteKit makes the most sense if you're experiencing very steep learning curve — complex backend configuration or outgrowing TYPO3's architecture. SvelteKit is best for teams wanting excellent performance with a simpler, more intuitive framework.
You should migrate if: your TYPO3 site is slow, your hosting costs are climbing, you need developer flexibility, or you want to adopt a modern JAMstack architecture.
You might want to stay if: your TYPO3 site benefits from handles massive multi-site installations (100+ sites from one instance) and you don't have JavaScript/TypeScript developers on your team.
The migration itself is straightforward with LeaveWP — enter your TYPO3 URL, select SvelteKit, and download your content. The more important question is whether SvelteKit's architecture fits your team's skills and your project's long-term needs.
