FormKeep alternative
FormKeep is a straightforward form backend with a real free plan. Teams move to Formpaste when they want automatic spam scoring instead of manually configured field rules, a quarantine folder for anything borderline, and copy-paste components for HTML, React, TypeScript, JavaScript, and Astro instead of a bare POST endpoint.

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 FormKeep?
Automatic, not manual
Formpaste scores every submission with heuristics out of the box - no honeypot fields or field rules to configure yourself.
Quarantine, not gatekeeping
Borderline submissions land in a folder you review and release, instead of you manually marking items as spam to train the filter.
First-class components
Copy-paste form components for HTML, React, TypeScript, JavaScript, and Astro - with a live preview per template, not just a form action URL.
Common FormKeep issues Formpaste solves
Spam filtering means configuring honey fields and field rules yourself
Formpaste scores every submission with heuristics automatically, with no setup required before you start collecting real submissions.
You have to manually mark spam to train the filter
Anything borderline goes to a quarantine folder you review and release yourself, so nothing depends on you flagging bad submissions after the fact.
Paid plans cap you at one form
Formpaste's plans include up to 3 forms, so a personal site and a couple of side projects fit on one account.
Free plan data disappears after a month
Formpaste doesn't put a retention window on your submission history.
Building the form UI from scratch for every framework
Copy-paste components for HTML, React, TypeScript, JavaScript, and Astro come pre-wired, with a live preview per template.
Why people leave FormKeep
FormKeep is a genuinely simple form backend, and its free plan is real: 50 submissions a month across unlimited forms, with no credit card required. Where teams outgrow it is spam handling and paid-plan limits. FormKeep’s spam protection is opt-in and manual - you turn on “Detect spam using submission data,” add a honeypot field, and write field rules yourself, then keep marking false positives so the filter learns. Formpaste scores every submission with heuristics automatically, with nothing to configure first. The other friction point is FormKeep’s paid tiers: the entry Essential plan, at $4.99 a month, only includes one form, and the free plan’s submission history is wiped after a month.
Migrating from FormKeep
Switching takes about two minutes and touches one line of your form. Point your
form’s action at https://api.formpaste.com/submit, add a hidden access_key
input with the key from your dashboard, and remove the FormKeep 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 spam scoring that works without manual setup, a quarantine folder for anything borderline, more than one form on a paid plan, or copy-paste components across HTML, React, TypeScript, JavaScript, and Astro. If you only need a single form, unlimited forms matters less than the number of forms per plan, and FormKeep’s free tier already covers your volume, there’s no urgency - the comparison above lists only shipped Formpaste features so you can decide honestly.
