The problem

Just looking inside an STDF is harder than it should be

01

STDF is not readable

It is a binary format. You need a tool or a script just to see what is inside.

02

The big tools are heavy

Enterprise platforms need licenses, installs, and setup for what should be a quick look.

03

Sharing means uploading

Passing data around often means sending your file to someone else's server.

Your file is processed securely on our servers. Nothing is stored, and everything is discarded the moment your session ends.
