The free Basin alternative

Basin is a form backend run from Canada that receives submissions from your own HTML forms, with a drag-and-drop form builder and AI tools on top. It suits freelancers and agencies collecting leads who want a deep spam toolkit and many integrations, and are fine with tiered paid plans beyond light use.

• A broad spam toolkit: reCAPTCHA, hCaptcha, Turnstile and domain restriction even on the free plan, plus country, language and disposable-email filters on Pro.
• Submissions over a paid plan’s quota are kept and billed per 1,000 rather than dropped.
• Zapier and a form builder on the free plan; native integrations and a REST API from Growth.
