Looking for a Formspree alternative?
Formspree popularised the no-backend form endpoint, but developers often outgrow it once they want chat notifications, built-in data destinations or first-class framework support. onsubmit.dev does the same core job — accept submissions from any HTML form with zero server code — and ships Telegram, Discord and Slack alerts plus Notion, Airtable and Google Sheets integrations out of the box. Here's how it stacks up against Formspree, Getform and Formspark.
Formspree vs onsubmit.dev — which one fits?
Formspree is a reasonable choice if you only need a plain email notification and you're already comfortable adding Zapier for anything else — it's mature, well documented, and its React helper works well if React is your only stack.
onsubmit.dev is built for teams that want that same "just an action URL" simplicity but expect notifications where they already work — Slack, Discord, Telegram — and integrations like Notion, Airtable, or Google Sheets without paying for a separate automation subscription. If you ship on more than one framework, official packages for Astro, React, Vue, Svelte, and Next.js mean you're not stuck copy-pasting the same fetch call into every project.

Why developers switch from Formspree to onsubmit.dev
Notifications where your team already is
Route every submission straight to Telegram, Discord or Slack — no Zapier in the middle. Formspree leaves chat alerts to third-party automations.
Built-in data destinations
Push entries to Notion, Airtable or Google Sheets out of the box. On Formspree those typically need a paid Zapier plan.
Drop-in framework packages
Official integrations for Astro, React, Vue, Svelte and Next.js mean one data attribute and you're done — Formspree only ships an official React helper.
A genuinely free start
Collect submissions for free with no credit card, then upgrade only when your volume grows.
Migration guide — swap one line of HTML
Migrating from Formspree takes seconds. Create a form in your onsubmit.dev dashboard to get an endpoint URL, then change the action attribute on your form. Your existing fields, method and markup stay exactly the same.
Before — Formspree
<form action="https://formspree.io/f/your-form-id" method="POST">After — onsubmit.dev
<form action="https://onsubmit.dev/f/your-form-id" method="POST">That's the entire migration. Submissions start arriving in your dashboard immediately, and you can wire up Telegram, Discord, Slack, Notion, Airtable or Google Sheets from the form settings without touching your markup again. Using React, Vue, Svelte, Astro or Next.js? Drop in the matching official package instead.
Pricing comparison
| Product | Free tier | Paid from | Notes |

Formspree switchers ask us
Can I keep my existing form fields and validation when I switch?
Yes. There's no schema to migrate — onsubmit.dev accepts whatever fields your form already sends. Change the action URL and everything else, including client-side validation and required attributes, stays exactly as it is.
Does onsubmit.dev support AJAX/JSON submissions like Formspree's fetch API?
Yes. POST JSON to the same endpoint with fetch instead of a full-page form submit, and handle the response however you like in your own JavaScript. See the docs for a working example.
What happens to spam protection when I switch from Formspree?
onsubmit.dev filters spam with a honeypot field and keyword filtering on every plan, plus OpenAI-powered AI antispam scoring on Basic and above that silently drops high-confidence spam and flags borderline entries for review.
Can I run Formspree and onsubmit.dev side by side while I migrate?
Yes. Switching is a per-form change to the action attribute, not an account-wide cutover — so you can move one form or one page at a time and leave the rest on Formspree until you're ready.
Does onsubmit.dev support a custom thank-you page like Formspree's _next field?
Yes. Set a redirect URL per form under Settings → Redirect and visitors land on your own page after submitting, or use the built-in thank-you page if you'd rather not build one.
Will I lose my past Formspree submissions when I switch?
onsubmit.dev can't pull historical data out of your Formspree account automatically — export what you need from the Formspree dashboard first. New submissions start arriving in your onsubmit.dev dashboard the moment you update the action URL.
