Basin

Basin is a form backend that receives submissions from any HTML form. It can also host forms you build in its dashboard, so no server code is needed.

You point a form's action URL at a Basin endpoint. Then you set up notifications, spam filters and auto-replies from the dashboard. Submissions can be stored, sent by email and passed to connected tools through webhooks. The service also handles file uploads, which is useful for application and contact forms that accept attachments.

• Works with any HTML form through an endpoint URL
• Spam filtering for incoming submissions
• Email notifications and auto-responses
• File uploads and webhook connections
• Forms you can build in the dashboard

Web developers, agencies and small teams that want a form process without running a server. The service suits sites built with React, Vue, Webflow or WordPress, as well as plain HTML pages.

You can start for free with a Google or email sign-in. Paid plans are listed on the site and unlock more features and volume. Check the details before you rely on them for busy forms. Filters catch most spam, but review your inbox rules as your traffic grows.
