Basin alternative
Basin is a feature-heavy form backend with AI spam filtering and a long list of dashboard tools. Teams move to Formpaste for a free tier that lasts 5x longer, copy-paste components for HTML, React, TypeScript, JavaScript, and Astro, and an MCP server their AI agent can drive.

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.

5x the free volume
Basin's free plan caps at 50 submissions a month. Formpaste's free plan gives you 250, so a side project runs far longer before you need a card.
First-class components
Copy-paste form components for HTML, React, TypeScript, JavaScript, and Astro - with a live preview per template, not framework guides.
Agent-native
An MCP server so your AI coding agent can create the form and wire it up on the first try.
Common Basin issues Formpaste solves
Basin's free plan runs out at 50 submissions a month
Formpaste's free plan includes 250 a month, so side projects and early-stage sites hit the paywall far later.
A spam-flagged submission is filtered, but there's no folder to review and release it
Formpaste holds anything borderline in a quarantine folder you check yourself, so a real message is never silently dropped.
No component library, just framework guides and a JS library to wire up
Copy-paste components for HTML, React, TypeScript, JavaScript, and Astro come pre-wired, with a live preview per template.
Your AI coding agent can't set the form up for you
An MCP server lets Claude Code, Cursor, or Codex create the form and return a wired snippet on the first try.
Webhooks and auto-responses are gated behind a mid-tier plan
Webhooks and autoresponders are included on Formpaste from the $9.99/mo plan, no need to size up first.
Why people leave Basin
Basin is a genuinely feature-rich form backend - AI-powered spam scoring via SpamCheck.ai, Cloudflare WAF, country and language filtering, and a dashboard with tagging and CSV export. The friction shows up in two places. First, the free plan: Basin caps you at 50 submissions a month, one-fifth of what Formpaste includes for free. Second, components: Basin ships framework guides and a JavaScript library (BasinJS) to wire up yourself, not copy-paste components. Formpaste takes a simpler position: a bigger free tier, real components for five frameworks, and a quarantine folder you review yourself instead of trusting an opaque spam score.
Migrating from Basin
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 Basin endpoint (it looks
like https://usebasin.com/f/{formId}). 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 a free tier that lasts longer, copy-paste components across HTML, React, TypeScript, JavaScript, and Astro, a quarantine folder for false positives, or an MCP server so an AI coding agent can wire the form up for you. If you specifically rely on Basin’s country/language filtering, Cloudflare WAF, or its AI spam scoring and don’t need components or MCP, check the comparison above first - we only claim what’s shipped.
