Basin

Form backend and form builder for collecting submissions without server code

Visit Basin

Basin is a hosted form backend and form builder that handles submissions for existing HTML forms and forms created in its own builder, removing the need to run server code. It collects submissions, filters spam, sends notification and auto-response emails, stores uploaded files, and fires webhooks, working with static sites, no-code projects, Jamstack apps, Webflow, WordPress, and JavaScript frameworks.

Features include the Form Studio drag-and-drop builder, HTML form backend, BasinJS library, and Basin API. Spam protection covers reCAPTCHA, hCaptcha, Cloudflare Turnstile, honeypots, and AI filtering via SpamCheck.ai. AI features include an AI Form Generator, Basin Chat, and an AI Lead Agent for scoring and tagging submissions. Integrations include Slack, Discord, Google Sheets, Zapier, Make, Pipedream, and webhooks. Additional capabilities include multi-step forms, file uploads with virus scanning, form analytics, submission inbox, custom email templates, custom domains, SMTP support, and GDPR tools.

Basin is aimed at individuals, freelancers, startups, agencies, and teams managing client projects. It offers a free plan with one form endpoint and limited submissions, a 14-day trial on paid plans, and paid tiers (Starter, Growth, Pro, Agency) with monthly submission allowances, file storage, and data retention limits. Collaborators are unlimited across plans. Additional submissions and storage can be purchased as usage-based add-ons, and Basin Chat is priced per token usage.
