Hi, I'm Fabian 👋🏼

I maintain several open source projects, including Valibot, Modular Forms, and Formisch. I also contribute to Qwik and created Standard Schema with @colinhacks and @ssalbdivad.

Valibot is a modular and type-safe schema library. Our ecosystem and community is growing day by day. Valibot is used by popular open source projects like Rolldown and is integrated into tRPC, React Hook Form, Hono, AI SDK and many more.

My long-term goal is to offer Valibot for free and actively contribute to the TypeScript ecosystem to improve the web for everyone. To achieve this goal, I need the support of organizations and individuals who benefit from my work.

It is important to me that this site is not aimed at private individuals and that nobody should feel obliged to make a donation. I work on Valibot, Standard Schema, and Modular Forms out of passion and have no direct financial expectations.

To show my gratitude, the logos of partners as well as the GitHub profiles of sponsors are listed in Valibot's documentation.

Thank you for your attention. Let's make the web better together!
