Attaform: type-safe, Zod-first forms for Vue 3 and Nuxt (full Zod 3 + 4 parity)

[ozzyfromspace]

Hi all! I built Attaform, a type-safe, schema-driven form library for Vue 3 and Nuxt where Zod is the first-class schema source.

The thing I most want to flag for this community: Attaform ships full first-class support for both Zod 3 and Zod 4 as equal peers. Every feature and every fix is built and tested against both adapters, so this is genuine parity. In practice that means teams still on Zod 3 get the complete experience today, and the door stays wide open to move to Zod 4 whenever they are ready, with no library migration on their side.

A few things that define it:

• Zod-first and type-safe end to end. Inference flows from your schema through useForm, so you rarely reach for a type by hand.

• Schema-driven state and rendering, not just validation. A v-register directive binds native inputs and your own components straight to the schema.

• SSR-ready for Nuxt, with correct server-rendered value / checked / selected.

• Zero runtime dependencies.

• Docs: https://attaform.dev

• Repo: https://github.com/attaform/Attaform

• npm: https://www.npmjs.com/package/attaform

I also opened PRs to add Attaform to the ecosystem docs, for Zod 4 (#6188) and Zod 3 (#6189). Sharing here for the Zod 3 crowd too, since first-class v3 support is a core commitment for Attaform, not a legacy afterthought. Happy to answer any questions!
