Basin handles web form submissions without requiring you to write server code.
What Basin is
Basin handles web form submissions without requiring you to write server code. It can collect entries, screen out spam, send email, store uploaded files, and pass data through webhooks. You can connect a form using HTML, Basin’s JavaScript library or API, or its no-code builder. Spam controls include CAPTCHA options, AI filtering, honeypots, domain restrictions, and other submission filters. The features page lists file uploads up to 50GB with virus scanning, while named integrations include Slack, Discord, Google Sheets, Zapier, Make, Pipedream, Integrately, and webhooks. Basin also lists Cloudflare WAF and DDoS protection, signed attachment links, token rotation, and HMAC-SHA256 webhook signatures. Privacy tools include data receipt emails, deletion, and configurable data retention. Submissions over a plan’s monthly cap continue to be delivered and incur the applicable tier rate.
