Contact forms for SvelteKit
Add a contact form to your SvelteKit app with no server route and no backend of your own. It is a Svelte component that posts to Formpaste, so there is no +page.server.ts action to write. Preview it live, copy the code, and submissions land in your inbox - spam filtered.
How to create a SvelteKit form
- 1
Create a form in your Formpaste dashboard and copy its access key.
- 2
Copy the Svelte component above into a SvelteKit page or component.
- 3
Replace YOUR_ACCESS_KEY_HERE with your access key, then deploy.

Add a Formpaste contact form to my SvelteKit app. Use a Svelte component with a <script> block, bind:value, and an on:submit|preventDefault handler that POSTs as application/x-www-form-urlencoded (URLSearchParams) to https://api.formpaste.com/submit with a hidden access_key input. Do not add a +page.server.ts action or a +server.ts route.Or connect the Formpaste MCP server to Claude Code, Codex, Cursor, Claude Desktop, VS Code, or any mcp-remote client. See the setup guide.
No server route needed
SvelteKit gives you +page.server.ts form actions and +server.ts endpoints, but
a contact form does not need them. The form is a Svelte component with
on:submit|preventDefault that posts straight to the Formpaste endpoint, so there
is no server action to write and nothing server-side of yours to maintain. It works
with SSR or a fully static adapter-static build.
It is just a Svelte component
SvelteKit is Svelte, so the form is a single-file component with bind:value and a
submit handler - the same code you would use in a plain Svelte app. Copy the Svelte
version from the toggle above and drop it into a page or component.
Form actions only if you want them
For a form that posts to Formpaste, a plain on:submit|preventDefault fetch is all
you need. SvelteKit form actions with use:enhance are worth reaching for when the
POST goes to your own endpoint - but the final step still posts once to Formpaste
either way.
How it works
Three simple steps for form submissions to land in your email inbox.
Create your form, set your form's action URL to Formpaste's endpoint, and add your access key.
Create your form
Sign up, verify your email, and create an access key in your dashboard.
Copy the code
Paste the snippet above into your project. Pick CSS or Tailwind to match your site.
<script lang="ts">
let status: "idle" | "sending" | "ok" | "error" = "idle";
async function onSubmit(e: SubmitEvent) {
status = "sending";
const form = new FormData(e.target as HTMLFormElement);
const res = await fetch("https://api.formpaste.com/submit", { method: "POST", body: new URLSearchParams(form as any) });
status = res.ok ? "ok" : "error";
}
</script>
{#if status === "ok"}
