Can submissions be sent to Slack or Google Sheets?

Yes, on paid plans submissions can go to Slack, Discord, Google Sheets, Notion, Airtable, Zapier and signed webhooks.

Does it work with WordPress or Webflow?

About Split Forms

Split Forms (splitforms) is a hosted form backend. Developers point any HTML, React, Next.js, WordPress or AI-built form at a single POST endpoint with a hidden access key, and each submission is spam-filtered, saved to a dashboard and emailed to the owner, with no server, PHP or SMTP to run. The endpoint accepts URL-encoded, multipart and JSON bodies, and works with static sites and builders such as Webflow, Framer and Carrd.

Spam filtering is rule-based on every plan, using honeypots, time-traps, per-IP rate limits and content scoring, with a reviewable spam folder and no CAPTCHA required. Paid plans add signed webhooks, file uploads, CC/BCC and auto-replies, Stripe payments on forms, and integrations with Slack, Discord, Google Sheets, Notion, Airtable, Zapier, Make and n8n. An MCP server lets AI agents such as ChatGPT or Claude create forms and return ready-to-paste markup.

The Free plan suits side projects and indie developers, while Pro and Annual plans target agencies and growing products. The service also offers 60+ free HTML form templates and a public status page.
