Custom Svelte renderers unlock the ability to use Svelte beyond the browser. This enables organizations to use the same technology across platforms like the web as well as native apps.
With custom renderers, teams can reuse UI code across different output formats, streamlining development and ensuring consistency wherever a user interface is needed.
Once the foundation for custom renderers is in place, the possibilities are endless. Beyond web and native apps, Svelte can power renderers for PDFs, video generation, terminal UIs, WebGL canvases, and more. This opens the door to a wide ecosystem of renderer-specific tooling and innovation—all while keeping Svelte at the core of your UI development.
Mainmatter has built a working prototype that proves this is not just an idea—it’s feasible and already functional.
But getting from prototype to a robust, production-ready foundation takes time and effort. If your company is excited about the potential of using Svelte across all your platforms, we invite you to sponsor the project. Your support will help us finish the implementation and make it stable, well-documented, and ready for everyone to use.
Mainmatter is here to empower your team to succeed with Svelte in your projects.
We offer a comprehensive range of Svelte and SvelteKit workshops, covering everything from foundational concepts to advanced techniques. Our experts also collaborate closely with teams already using Svelte—accelerating development, solving complex challenges, and providing hands-on mentoring directly within your projects.
