Form backend
for developers
Get a unique URL per form. Set it as your form's actionattribute and you're done — Form Fuse handles storage, AI spam filtering, email delivery, and webhooks.
<!-- No API key. No backend. Just a URL. -->
<form
action="https://f.skyb.in/f/ff_contact_01"
method="POST">
<input name="name" type="text" />
<input name="email" type="email" />
<textarea name="message"></textarea>
<button type="submit">Send</button>
</form>
<!-- submissions stored, spam-filtered, emailed — done -->Skip the boilerplate
Every form backend needs the same infrastructure. Form Fuse ships it all, so you ship your product.
How it works
Three steps from signup to handling production submissions.
Create a form
Register a form in the dashboard. Get a unique endpoint URL instantly — no API key required.
Point your form at it
Set the URL as your form's action attribute. Or POST JSON to /j/{id}. No auth required.
Get results
Submissions are stored, spam-filtered, and routed to your webhook or email immediately.
Only the submissions that matter
Every submission passes through a multi-stage AI pipeline before it reaches your inbox. Set a category or write your own filter — Aastha AI enforces it in real time.
Email validation
Syntax check + disposable domain filtering via the community-maintained disposable-email-domains list. Thousands of throwaway providers blocked before the AI pipeline runs.
Intent pre-filter
A fast AI classifier scores the submission. High-confidence spam is stopped here — no further processing needed.
Category filter
A deep model evaluates the submission against your chosen category or custom prompt. Only genuine intent passes.
Pick a category
Tell the AI what your form is for. It uses that context to judge whether each submission reflects genuine intent.
Or write your own filter
Give the AI a plain-language instruction. It becomes the qualification criteria for every submission your form receives.

Response reference
Two endpoints, two response styles — choose what fits your stack.
Real leads. Real feedback. Zero noise.
What your inbox looks like when every submission is pre-qualified before it reaches you.
Only contacts with genuine business interest — filtered by your category or custom prompt.
“Looking to replace Typeform for our enterprise onboarding flow. Can we schedule a demo?”
→ forwarded to your inbox
“Congratulations! You have been selected for a special offer...”
→ blocked, reason logged
Real emails only — disposable addresses and throwaway signups filtered out automatically.
→ webhook fired · added to your CRM
Genuine enquiries only — low-effort messages and bot submissions never reach you.
“We need a custom form solution for our agency clients. What does the Agency plan include?”
→ forwarded to your inbox
Actionable feedback from real users — noise filtered, genuine insights delivered.
“The webhook retry logic saved us — had a 2-hour outage and zero submissions were lost.”
→ forwarded to your inbox
Tested in production
Skybin.io ran FormFuse on their contact form for 6 months. Here's what happened.
The situation
Over 6 months, 292 submissions arrived. 291 were spam — bots with random names, product ads disguised as enquiries, SEO spam. Manual filtering was consuming hours every day while the one real business lead was buried in the noise.
