Build forms into your product with your coding agent. Fillo handles the infrastructure behind them: validation, uploads, responses, versions, and delivery.

Hi Product Hunt! 👋

I’m Jacob, the maker of Fillo.

Whenever I needed an onboarding form, survey, or file-upload flow, I kept facing the same choice:

a) embed a hosted form in an iframe that never quite felt like part of the product, or 

b) build it natively and take on validation, uploads, notifications, webhooks, and response management myself.

File uploads made the tradeoff even worse. We often need to collect files around 500 MB, ideally straight into our own storage.

So I built Fillo: headless form infrastructure for product teams.

Build forms into your product or website with your coding agent. They render directly in your own routes, with your layout, styles, and components. No iframe. Fillo handles schema, validation, browser-direct uploads, responses, notifications, and webhooks.

You can upload files directly to Google Drive, Box, or S3/R2 storage.

Fillo is for forms that need to feel like a real part of your product.

We’re launching today, and I’d love to hear what you think. Try it out and send me your feedback here.

we collect files around 500 mb so browser direct into our own s3 matters. if the tab dies halfway, resume or start over

@niveditha_patluri1 Exactly, Fillo automatically resumes or discards the submissions you don't finish.

Tried the agent setup. Literally one prompt and it was live on all help pages on rotato.app

@mortenjust , very happy to hear! It looks great on your site!
