About Basin

Basin is a hosted form backend for people who build websites without writing server code. A form's action URL is pointed at a Basin endpoint, and the service takes care of receiving each submission, filtering spam and delivering it to an inbox or connected tool. It works with plain HTML as well as with React, Vue, Webflow and WordPress.

From a dashboard, users configure notification emails, auto-responses, spam filters, file uploads, integrations and webhooks. Basin also includes its own form builder for those who prefer not to hand-code markup, and the vendor has recently introduced AI-generated landing pages aimed at lead capture.

Basin is a commercial service with a pricing page and a free way to start, aimed at agencies, businesses and creators who manage forms for several sites. The vendor also publishes documentation, platform guides, an integrations list and a comparison page against other form products.
