Splitforms alternative
Splitforms is a close match to Formpaste - both quarantine suspicious mail instead of gatekeeping real visitors, and both ship an MCP server for AI coding agents. Teams pick Formpaste when they want real copy-paste components for HTML, React, TypeScript, JavaScript, and Astro instead of framework guides, with Tailwind and CSS built in.

How it works
Three steps from sign-up to form submissions landing in your inbox.
Create Your Form
Sign up for an account. Verify your email and create an access key in your dashboard.
Create Contact Form
Add the code snippet using your favourite language to create the form.
<form action="https://api.formpaste.com/submit" method="POST">
<input type="hidden" name="access_key" value="YOUR_ACCESS_KEY_HERE">
<input type="email" name="email" placeholder="Your email" required>
<textarea name="message" placeholder="Your message" required></textarea>
<button type="submit">Send</button>
</form>Add Access Key
Replace with your access key to start receiving email submissions.
<input type="hidden" name="access_key" value="YOUR_ACCESS_KEY_HERE">Why switch from Splitforms?
Components, not guides
Splitforms points you to framework guides you implement yourself. Formpaste ships copy-paste components for HTML, React, TypeScript, JavaScript, and Astro, with CSS and Tailwind included.
Quarantine, not gatekeeping
Both hold suspicious submissions for review instead of gating visitors behind a CAPTCHA - Formpaste's quarantine folder works the same way, with nothing hidden from you.
Agent-native from the same starting point
Both ship an MCP server, so this comparison isn't about who has agent support - it's about which components your agent hands back once the form exists.
Common Splitforms issues Formpaste solves
You want the form written for you, not a guide to follow
Copy-paste components for HTML, React, TypeScript, JavaScript, and Astro come pre-wired and styled with CSS or Tailwind - paste and go.
File uploads and autoresponder are locked behind a paid tier
Formpaste's free plan includes file uploads, webhooks, and autoresponder from day one - no tier to unlock.
You're not sure which framework guide applies to your stack
Formpaste's components are the actual code for HTML, React, TypeScript, JavaScript, and Astro, not a docs page you translate yourself.
Why people leave Splitforms
Splitforms is a genuinely close competitor - it already does the two things that usually make teams leave a form backend: a quarantine folder instead of a CAPTCHA, and an MCP server for AI coding agents. Where it comes up short is the integration itself. Splitforms hands you framework guides for React, Next.js, Vue, and Astro - documentation you read and adapt by hand. Formpaste hands you the component: copy-paste code for HTML, React, TypeScript, JavaScript, and Astro, styled with CSS or Tailwind, ready to drop into a page. File uploads, webhooks, and autoresponder also start on Formpaste’s free plan, where Splitforms gates some of them behind a paid tier.
Migrating from Splitforms
Switching takes about two minutes and touches one line of your form. Both
services use the same pattern - a plain POST with a hidden access_key input -
so point your form’s action at https://api.formpaste.com/submit, swap in the
access key from your Formpaste dashboard, and remove the Splitforms endpoint.
Your existing field names keep working - Formpaste emails you whatever fields
you POST. No code rewrite, no framework lock-in.
Who should switch - and who shouldn’t
Switch if you want the actual component code for your framework instead of a guide to implement yourself, or if you want file uploads, webhooks, and autoresponder included on the free plan rather than gated. If Splitforms already covers what you need - and its quarantine folder and MCP server are real, not marketing - there’s no urgency to move. This page only claims what Formpaste has shipped, so you can compare honestly.
When Formpaste is not the right choice instead of Splitforms
You need submissions stored in a database you query, not delivered by email and browsed in an inbox.
You need a visual form builder for non-technical teammates. Formpaste is a paste-a-snippet endpoint, so someone has to edit the page's markup.
You need HIPAA or SOC 2 attestation today.
Splitforms already covers what you need, including its own MCP server for AI coding agents. If a framework guide is enough and you don't need a pasteable component or a quarantine folder, there's no urgency to move.
