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

Who hunted Fillo?
Fillo was hunted by Jacob Funch. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
