Self-attest documents online - Free & OpenSource

My startup Foore (https://foore.in) is in the process of getting acquired which means signing and self-attesting a lot of documents.

On a normal day, this is a bearably painful exercise, but visiting a photocopy shop is kinda unsafe during these COVID times.
So, I searched online and to my surprise, there were either shady websites or sign-up walls.

Hence https://selfattest.online was born.

It's open-sourced and completely free.

I hope it will be beneficial for indiehackers community :)
Feedback and PR welcome!
