About SubmitKit
A form backend for teams that do not want to maintain one.
SubmitKit helps static sites, landing pages, and SaaS products accept form submissions without custom backend code. The product handles submission storage, email notifications, spam filtering, file uploads, and webhook delivery behind a simple form endpoint.
Hosted form endpoints
Point any HTML form at a SubmitKit endpoint and receive submissions without writing an API route.
Email notifications
Send formatted owner notifications and optional auto-responses when a form is submitted.
Spam controls
Use honeypot checks, timing checks, and rate limits to reduce low-quality submissions.
Webhooks and exports
Forward submissions to other tools and export stored entries when your workflow needs them.
Who is it for?
SubmitKit is for developers and founders who need reliable forms, but do not want every contact form, waitlist, application form, and file upload form to become a backend project.
It is especially useful for static sites, Next.js apps, portfolio sites, marketing pages, product waitlists, support forms, lead capture forms, and lightweight internal workflows.
When a form needs deep custom business logic or direct writes into an internal system, a custom backend can still be the right choice. SubmitKit is built for the many forms where reliability, delivery, storage, and speed matter more than owning infrastructure.
