Easy as 1, 2, 3
The same create → configure → collect flow Typeform popularized — without replacing your frontend.
Design your form anywhere
Use your own HTML, React components, Webflow, or WordPress — no locked-in builder. Copy a Form Fuse endpoint URL from the dashboard.
Set rules once in the dashboard
Pick spam category, custom AI filter, email alerts, webhooks, and Slack — the same configure-once workflow Basin and Typeform emphasize.
Act on qualified submissions
Legit leads hit your inbox and CRM. Review classifications, export CSV, and tune filters from real submission data.
Skip the boilerplate
Every form backend needs the same infrastructure. Form Fuse ships it all, so you ship your product.
Setup
Live in 3 steps
From signup to handling production submissions in under 5 minutes.
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.
One platform
Everything after the submit click
Form backends like Basin handle collection and routing. Form builders like Typeform own the UI. Form Fuse focuses on what happens next — storage, qualification, and delivery — while you keep full control of your form design.
Submission inbox
View, search, and review every submission in one dashboard — legit, low-intent, and spam, with AI reasons attached.
AI lead qualification
Pick a form category or write a plain-English filter. Only submissions that match genuine intent reach your inbox.
Layered spam protection
Disposable email blocking, fast intent pre-filter, and deep category scoring — inspired by best-in-class form backends.
Email notifications
Instant alerts when a legit lead arrives. Configure per-form delivery without touching your backend.
Webhooks & integrations
Push submissions to Slack, Discord, or any URL. Route clean leads to your CRM, Zapier, or custom pipeline.
Team notifications
Slack and Discord alerts keep sales and support in the loop the moment a qualified submission lands.
Dashboard analytics
Track submission volume and classification breakdown over time — see what your forms are actually collecting.
Export & audit
CSV export on every plan. Spam and low-intent submissions stay stored for review — nothing disappears silently.
Only the leads that matter
Every submission passes through a 3-stage AI pipeline before it reaches your inbox. Set a category or write your own filter — enforced in real time on every submission.
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.

In practice
What reaches your inbox
Every submission is pre-qualified before it reaches you. Here is what that looks like across four common form types.
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
disposable address detected
→ blocked at email validation
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
“hi”
→ stored, not forwarded
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
“Great site! Check out our SEO services at...”
→ blocked, reason logged
99.7% spam caught.
Zero false positives.
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.

“FormFuse completely transformed our lead generation. We went from drowning in spam to focusing on real opportunities. The AI catches everything we don't want while never blocking genuine inquiries.”
“We make our page in React and send signups to a form endpoint — no backend to maintain. Exactly the Basin-style workflow, with AI filtering baked in.”
“Our contact form went from 291 spam entries and one real lead to zero noise in the inbox. The dashboard still stores blocked submissions for audit.”
