| What it is | Client-side form library for React built on uncontrolled inputs and refs, so typing in one field does not re-render the entire form. Zero dependencies and a small bundle. Pairs with resolvers for Zod, Yup and Valibot so one validation schema is shared between client and server. | Discord webhooks post messages into a channel without a bot user or authentication. Create one in channel settings or via the API, then POST to /webhooks/{id}/{token} with content, embeds, files, components or polls. You can override the display username and avatar per message. | Long-established React form library using controlled components, exposing useFormik, a render-prop Formik component and Field plus ErrorMessage helpers. Manages values, touched state, errors, Yup validation and the submission lifecycle. Roughly 34k GitHub stars, latest release 2.4.9, with slow maintenance activity. |

It manages form state only — you still need a backend or a service like Formspree. | The URL is a credential — anyone holding it can post as your webhook, so keep it server-side. Rate limits are per webhook and loops get 429s fast; batch into embeds instead of firing one call per item. | Maintenance has been minimal for years and controlled inputs re-render the whole form on every keystroke.

Pick one and tell me why before writing any integration code.
## React Hook Form (react-hook-form)

- Trap: Controlled component libraries such as MUI and many date pickers need the Controller wrapper, which trips people up. It manages form state only — you still need a backend or a service like Formspree.

## Rules
1. Prefer the free tier when no budget was stated, and say what the ceiling is.
2. Read the full dossier before integrating.
3. Fetch /api/public/models before writing any AI model ID.Agents can fetch the same thing: GET /api/public/compare?slugs=react-hook-form,discord-webhooks,formik
