When should I use Fillo?

Use Fillo when the form belongs inside your product—such as onboarding, support, feedback, intake, file requests, and approvals that require your routes, components, account context, or ongoing maintenance.

Does Fillo render inside an iframe?

No. Fillo renders native UI controls rather than an iframe, letting you use the default renderer, replace fields with your own components, or build with headless hooks.

How do file uploads work with Fillo?

Files upload browser-direct to your connected cloud storage (such as Amazon S3, Cloudflare R2, Google Drive, or Box) while Fillo maintains the response and file references together.

Can I build forms using a coding agent?

Yes. Your coding agent installs the Build-with-Fillo skill, provisions the form, adds the native render code, and provides a live preview.
