AI Can Build Your UI in Seconds. Who's Handling the Forms?

We Keep Reinventing the Same Wheel

Every project I've started in the last five years has had the same moment. You build the UI, you wire up state, you get the design looking sharp — and then someone says "we need a contact form." Or a feedback form. Or a waitlist sign-up.

And you spend the next afternoon doing the same thing you've done a dozen times before: writing a route that accepts a POST, validating the body, pushing rows into a Google Sheet, sending a confirmation email, hoping nothing breaks at 2am.

FormProxy exists because I got tired of that afternoon.

What FormProxy Actually Does

FormProxy is a form backend. That sounds small until you think about what "form backend" actually means:

Accepting submissions from any HTML form or API call, without you writing a handler
Storing everything with configurable retention (7 days on free, 90 days on paid plans)
Routing submissions to wherever your team actually lives — Slack, email, Google Sheets, webhooks, Zapier
Managing multiple forms across workspaces, with per-form signing secrets and activation toggles

You drop a form endpoint URL into your <form action="..."> and you're done. No backend code. No database schema. No queue to maintain.

Why This Matters Even More Now That Everyone Has AI

Here's the thing nobody says out loud: AI has made it dramatically easier to build frontends, but the boring infrastructure behind forms hasn't gotten any smarter.

ChatGPT or Claude can generate a beautiful, accessible contact form in seconds. Cursor can wire up the validation. But the moment that form needs to do something — store a submission, notify Slack, sync to a spreadsheet — you're back to writing SMTP handlers and webhook endpoints by hand.

The gap between "AI can build my UI" and "AI can run my backend" is real. Tools like v0 and Lovable and bolt.new are accelerating frontend development faster than infrastructure can keep up.

FormProxy fills exactly that gap. When your AI-generated landing page needs a "Join Waitlist" form that:

Stores signups with timestamps
Pings your team in Slack instantly
Syncs every row to a Google Sheet your non-technical co-founder can read
Sends a confirmation email to the user

...you don't need to write any of that. You configure it in a UI and point your form at the endpoint.

The Integrations Are the Point

The real value isn't storage — it's routing. Here's what FormProxy can do with a submission the moment it lands:

Google Sheets

Every submission becomes a row. Columns are inferred automatically from your form fields — add a new field to your form and it appears as a new column on the next submission, no schema migration required.

We use Google's OAuth flow with drive.file scope (not the overly broad spreadsheets scope), so you retain control of exactly which files FormProxy can touch. You pick the spreadsheet via a Picker UI — no copy-pasting spreadsheet IDs.

Slack

Instant notification to any channel. Good for lead forms, support requests, anything your team wants to see in real-time.

Webhooks

Full POST to any URL with HMAC signing (using the form's signing secret), so your own services can verify the submission is genuine before processing it.

Email

Confirmation emails to submitters, notification emails to your team. Configurable templates, no mail server setup on your end.

Zapier

One integration that unlocks 5,000+ apps. If FormProxy doesn't have a native integration for your tool, Zapier fills the gap.

A Real Example: AI-Generated SaaS Landing Page

Here's a workflow I've used in production:

Use v0 to generate a landing page with a "Get Early Access" form
Point <form action="https://app.formproxy.com/f/{uid}"> at FormProxy
Configure: Google Sheets sync (so I have a CRM-lite spreadsheet), Slack notification (so I see signups immediately), email reply (so users get a confirmation)
Done in under 10 minutes

No Netlify Functions. No serverless cold starts. No "oh we missed 3 signups because the function timed out."

The AI built the frontend. FormProxy handled everything else.

What's Next

We're actively building:

AI-powered submission summaries — ask natural language questions about your form data
Conditional routing — send to Slack only if a field contains a certain value
Team comments on submissions
File uploads — already supported on paid plans, expanding to more types

If any of this resonates, try it: app.formproxy.com. Free tier is genuinely useful — 3 forms, 7-day retention, all integrations.

Would love to hear what integrations you'd want to see next. Drop a comment.

FormProxy is built with FastAPI + Next.js
