Put one URL in your form's action and stop writing form handlers. Submissions are stored in the EU or the US, spam is held back, and the people who need them get an email.
The commission form from a ceramics studio's site. Change a field and see what the endpoint answers and what lands in the studio's inbox. Nothing leaves your browser.

Post plain HTML, send JSON with fetch, or call it from your server with a Submit Key. Whatever fields arrive get stored, so there's nothing to declare first.

</form>Link a Project to your Sanity project. The Studio plugin, which we're building now, gives your editors a Submissions tool, and the role they already have in Sanity decides what they can do there.
Submissions stay with Insane Forms and never enter your dataset. Until the plugin ships, they're in the dashboard. What's ready today

Custom and unknown roles can read, and nothing more.
Every Form checks a honeypot field and rate limits each visitor and each Form. Turn on Allowed Origins or Cloudflare Turnstile where a Form draws targeted spam. Caught Submissions wait in Spam for 30 days, send no email and don't count towards your Plan. Spam protection
A plain HTML form can send files with the Submission, up to 4.5 MB in all. Direct uploads take bigger files straight to storage, up to 25 MB each on the beta Plan. Every file is private and opens through a link that expires. File uploads
Each Form has its own Recipients. They get every field and a link to each file. When the form asks for an email address, a reply goes straight to the visitor. Switch a Form to link-only and the email carries a link to the Submission instead. Notifications
Download what you're looking at as CSV or JSON. Large exports run in the background and email you a link that works for 7 days. Submissions and exports
Being built now: the Sanity Studio plugin, a React library, a REST API, signed webhooks, a Zapier app, an n8n node and an MCP server. Each one gets its docs the day it ships.
A Workspace picks its Region when it's created and keeps it. Choose one below and see what lives where.
A Notification travels by email, so no Region can hold it. Switch a Form to link-only emails to keep the values in the Region. Regions and your data
Free during the beta, with 1,000 Submissions a month for each Workspace. Create a Form, copy its URL and paste it into your form's action. That's the whole integration.
