BASIN ALTERNATIVE

Everything Basin does, with a free tier that goes further

Formstork is a form backend for HTML, React, Vue, Svelte and more. Point your form at our endpoint and submissions land in a searchable dashboard, with free integrations, a no-code builder and a rules engine built in.

What is Basin?

Basin is a headless form backend made in Canada by Moonshot Ventures: you code your own HTML form, point it at Basin, and it handles submissions, spam and integrations. Its free plan covers 1 form and 50 submissions a month with 30-day retention, and unlimited forms only arrive at the mid Growth tier ($24.17/mo), where Slack, the API, webhooks and auto-responses also unlock.

A free plan you can grow on

Basin's free tier stops at 50 submissions on 1 form with 30-day retention. Formstork gives 250 a month kept for 90 days, no card, with a searchable dashboard and CSV plus JSON export.

Integrations without the mid-tier jump

On Basin, Slack, Google Sheets, the API, webhooks and auto-responses only unlock at the Growth tier ($24.17/mo). Formstork ships Slack, Discord, Telegram, Sheets, Notion and HMAC webhooks free on every plan.

SDKs, an MCP server and a hosted builder

Basin is a headless endpoint you wire up yourself. Formstork adds React, Vue, Svelte and JS SDKs, an MCP server and a no-code hosted builder, while still working as a plain endpoint.

Switching takes one line

Point your form's action at your Formstork endpoint and use your access key. There is no data migration and your existing markup keeps working.

<form action="https://api.formstork.com/submit" method="POST">
  <input type="hidden" name="access_key" value="YOUR_KEY">
  <input type="email" name="email" required>
  <textarea name="message" required></textarea>
  <button>Send</button>
</form>

The honest verdict

Basin includes file uploads from its free plan and adds virus scanning and custom SMTP on Pro, so if attachments matter on day one it has a real edge. For a bigger free tier, free integrations, client SDKs with an MCP server, a no-code builder and a lower price at 10,000 submissions, Formstork comes out ahead.
