We built Fillo because we often need file uploads and they need to be private. Making our own forms with nice uploads became a maintenance and implementation task over and over. Most form builders support 10mb or one file per form; we needed 500mb or 10-20 files per form.
It's a native form, not an embedded iframe. The browser sends the file directly to S3/R2/Box/Drive, and Fillo handles the rest.
I’d love feedback!
