About onsubmit.dev

onsubmit.dev is a hosted form backend: you point a plain HTML form's action attribute at a generated endpoint, or POST to it with fetch, and every submission is captured and fanned out to wherever your team already works. There is no server to run, no database to provision and no deploy step, which is the whole argument for the category — the product replaces the small piece of backend code that otherwise has to exist purely so a static site can receive a message. Onboarding is deliberately account-light: you enter an email, verify a six-digit code, and the endpoint is issued, with no password and no credit card. Because it only requires the ability to send a POST, it is framework-agnostic by construction, and the vendor lists React, Next.js, Vue, Nuxt, Svelte, Astro, Hugo, Gatsby, Eleventy, Jekyll, WordPress, Webflow, Shopify and the major static hosts among supported integrations. Thirteen notification channels are available: email, Telegram, Discord with rich embeds, Slack Block Kit messages, signed webhooks with optional HMAC, Zapier catch hooks, n8n, Notion, Google Sheets, Airtable, Jira and IFTTT. Paid tiers add anti-spam protection, file attachments, multi-email notifications, custom redirect and thank-you pages, white-labelling and an AI auto-reply. The site publishes a direct comparison against Formspree and maintains a status page.
