A free, fully hosted form backend. Create a form, get an API endpoint instantly, and collect submissions — no server, no database, no coding required.
WHY WE BUILT IT
Every static site or landing page eventually needs a contact form, and every contact form needs somewhere to send its data. FastSubmit is that somewhere — an endpoint you can point any form at, free, with no backend of your own to build or maintain.
WHAT IT DOES
Create as many forms as you need with custom fields — no cap on forms, submissions, or fields on the free plan.
Every form gets a ready-to-use endpoint the moment you create it — point your site's form at it and submissions start flowing.
View, search, and manage every submission from a single dashboard — no database to set up yourself.
Export any form's submissions to CSV whenever you need them outside the dashboard.
Fetch submissions programmatically with an API key — build your own views or pipe data into other tools.
Built-in honeypot fields filter out basic bot spam without adding a CAPTCHA to your form.
QUICK LOOK
POST /api/submit/{formId}
Content-Type: application/json
{ "name": "John", "email": "[email protected]" }Fetch it back out any time with GET /api/forms/data/{formId}?apiKey=YOUR_API_KEY.
QUESTIONS
Yes — unlimited forms, submissions, and API access, forever free, with no credit card required.
No. FastSubmit is the backend — point your HTML form's action at the auto-generated endpoint, or call the API directly, and submissions are stored and viewable in your dashboard immediately.
Yes — since it's just an API endpoint, it works anywhere you can send an HTTP request from: a static site, a landing page builder, a bio-link page, or a script.
View them in the dashboard, export to CSV, or fetch them programmatically via the REST API with your form's API key.
