Web3Forms alternative
Web3Forms is a solid no-backend form endpoint. Teams move to Formpaste when they want more control over spam - a quarantine folder they review instead of a honeypot-or-CAPTCHA choice - plus a submission-history dashboard and an MCP server their coding agent can call.

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 Web3Forms?
Quarantine you control
Instead of silently dropping or waving through borderline mail, Formpaste holds suspicious submissions in a folder you review and release.
A real dashboard
See every submission with history and export, not just an email notification.
Built for AI agents
An MCP server lets your coding agent create a form and wire it up without visiting a dashboard.
Common Web3Forms issues Formpaste solves
A borderline submission vanished and you never knew
Formpaste holds suspicious mail in a quarantine folder you review and release, so nothing is silently dropped.
You only have the email notification, no record
Every submission is stored in a dashboard with history and CSV export, not just fired off as an email.
Turning on hCaptcha to stop spam hurts your conversion
Spam is filtered by heuristics with no CAPTCHA widget, so visitors never solve a puzzle.
Wiring the form by hand across every framework
Copy-paste components for HTML, React, TypeScript, JavaScript, and Astro come pre-wired - or your AI agent does it over MCP.
Not sure a notification actually reached your inbox
Notifications send from formpaste.com with aligned DKIM/SPF and reply-to set to the submitter - no DNS setup on your end.
Why people move from Web3Forms
Web3Forms is a genuinely good no-backend endpoint, and the two products overlap on the basics. Where teams outgrow it is control and visibility. Web3Forms filters spam with a honeypot and optional hCaptcha - fine until a borderline message gets dropped and you never know it existed. Formpaste holds those in a quarantine folder you review and release, and keeps a full submission history in a dashboard rather than living entirely in your email. If your integration decisions are increasingly made by an AI coding agent, Formpaste’s MCP server lets that agent create the form and return a wired snippet directly.
Migrating from Web3Forms
The move is a one-line change. Both services take a plain form POST with a hidden
access_key, so switching means swapping the action URL to
https://api.formpaste.com/submit and pasting your Formpaste access key. Your field
names and markup stay exactly as they are.
Who should switch - and who shouldn’t
Switch if you want a quarantine folder for false positives, a submission-history dashboard, or agent-native setup via MCP. If Web3Forms already covers everything you need and you don’t want a review folder or a dashboard, there’s no urgency - the comparison above lists only shipped Formpaste features so you can decide honestly.
