Hey Product Hunt community!
I'm currently building OnlyBills, a free GST tax invoice generator. While coding, I made a strict design decision: No registration. No databases. Zero logins.
All user data, client profiles, and billing history stay saved locally inside the browser's storage (we support JSON backups so you don't lose data when clearing cache).
I did this because I hate having to create yet another account just to generate a quick PDF. But I've had colleagues tell me: "You're losing out on building an email list for marketing!"
the no signup thing is refreshing, just opened it and had an invoice ready in under a minute
Love that the whole thing works without forcing a signup first. The preview-before-download flow feels really considered, especially the way it lays out line items and tax splits in a clean PDF.
