Show HN: A Free, Offline-First Cash Register That Runs in the Browser

[gerardojbaez]

Hey HN – I built a simple web-based cash register called Take a Sale: https://takeasale.com

It’s a PWA that works entirely offline, no backend required. The idea is to give small shops and independent sellers a reliable alternative to clunky physical registers or bloated cloud POS systems. You open it in the browser (or install it as an app) and start selling — you can optionally configure your own products and prices, but it works out of the box.

It’s built with Vue.js + TypeScript, using a modular architecture based on Clean Architecture and DDD principles. Everything is designed to be offline-first — no tracking, no login, and no dependencies on any cloud infrastructure.

The core register is staying free. Eventually, I’ll offer optional add-ons like cloud sync, Google Drive backups, or a “back office” to manage data centrally — but the main idea is to have a fast, privacy-friendly POS that just works.

Would love feedback - on the concept, UI/UX, etc.

Thanks for checking it out.
