onsubmit.dev

This service lets you point a plain HTML form at a unique endpoint and start receiving submissions without building or hosting a backend. It is aimed at static sites, contact forms, mobile apps, and other simple submission workflows where you want form data delivered quickly and managed in one place.

After verifying your email, you get a unique form endpoint to paste into your HTML. From there, each submission can trigger instant notifications by email, Telegram, Discord, Slack, webhooks, Zapier, n8n, IFTTT, Notion, Google Sheets, Jira, or Airtable, depending on the plan and destination. The product also includes an AI antispam layer that uses OpenAI-powered scoring to drop high-confidence spam and flag borderline submissions for review.

Users can view, search, and export submissions from a dashboard. File uploads are supported for HTML forms, with files stored securely and accessible from the dashboard on the Pro plan. The service says data is stored and processed in the EU, with GDPR compliance by default, and it advertises a 99.9% uptime guarantee.
