</form>Works with any technology
Built for indie devs, agencies, and anyone tired of writing the same backend twice.
Create an endpoint, paste one hidden field into your HTML, and you're done. No npm install. No deploy step. No CORS headaches.
Every submission lands in your inbox with reply-to set to the sender. Hit reply — the conversation just works. Auto-responders included.
Honeypot fields catch bots before they ever reach your inbox — without forcing humans through a single CAPTCHA. Per-IP rate limits stop floods automatically.
Every lead, every message, in one place. Mark as read, flag spam, see exactly who submitted and when — even if email delivery hiccups.
Pipe submissions into Slack, Discord, Notion, Zapier, Make, or your own API. Trigger workflows the moment a lead drops in.
HTTPS everywhere, XSS-sanitized inputs, bcrypt-hashed passwords, and per-form domain locking. Rotatable access keys mean leaks aren't catastrophic.
Three steps. Under a minute. No server needed.
Sign up and create your first form. You get a unique access key instantly.
Create your formPoint your form's action at our API and include your access key as a hidden field.
<form action="https://app.optaristo.com/api/submit" method="POST">
<!-- Your access key -->
<input type="hidden" name="access_key" value="YOUR_ACCESS_KEY">
<input type="text" name="name" required>
<input type="email" name="email" required>

</form>Every submission lands in your email and your dashboard. That's it — you're done.
No credit card. No usage caps. No "free tier" gotchas. While Optaristo is in beta, every feature is unlocked — unlimited forms, unlimited submissions, webhooks, auto-responses, the works. When paid plans launch, beta accounts keep their data and a free tier stays.
Optaristo acts as the backend for your HTML forms. Instead of setting up a server to receive form data, you point your form's action URL at our API and include an access key. We handle storing the submission, emailing you, and giving you a dashboard to manage everything.
Nothing right now. Optaristo is free during the beta with no limits on forms or submissions. When we introduce paid plans down the road, there will always be a free tier and existing beta users won't lose access to their data.
Yes. The access key identifies your form endpoint — it's not a secret. Think of it like a mailing address: people can send you mail, but they can't open your mailbox. For extra protection, you can lock a form to only accept submissions from specific domains.
Basic HTML is all you need. If you can write a <form> tag and paste in a hidden field, you're set. We provide ready-to-copy code snippets in the dashboard. For developers, we also support JSON submissions via fetch or any HTTP client.
Every submission is stored in your dashboard regardless of whether the email goes through. You can log in anytime and see the full history of submissions, mark them as read, or delete them.
Yes. Optaristo works with anything that lets you set a form's action URL: static HTML, React, Vue, Next.js, Astro, WordPress, Webflow, Squarespace, Framer, and more. If it renders a form, it works.
Add a hidden field called _gotcha to your form. Bots fill every field they find, but real users never see it. If it has a value, we flag it as spam. We also rate-limit submissions per IP to prevent flooding.
