Open Source Barware: Free, Local-First Inventory Software for Bars

I built Open Source Barware to end the expensive, painful cycle of bar inventory management. This free, open-source program runs locally on your laptop, requiring no subscriptions or vendor lock-in. It combines smart spreadsheets, variance tracking, and optional AI for invoice scanning, all crafted by bartenders for the trade to reclaim your time and tips.

Because a good program shouldn’t cost you a shift’s worth of tips.

    I’m sorry to waste so many comments complaining about how people use AI but the phrasing above sits in uncanny valley for me.

    I don’t know if the culture around consumption of vibe coded apps is different and the style used to describe projects is optimal for that audience , or if the projects simply don’t have an audience so the uncanny tone is just not an issue.

    Why does it need cloud AI to read invoices? Basic foss OCR can do this very well, so too the most basic local AI. Wrangling claude to read reciepts is using a tomahawk to kill ants.

    Can i point it at a local AI server? Can i feed it a pdf that i make myself using my own OCR?

    I don't know much about running a bar apart from being a regular and sticking around for closing time every now and then.

    This looks like an opinionated frontend for a spreadsheet. There are tons of those already. Does this really reduce any of the complexity well enough to be better?

    I think people would be more convinced with a demo compared to the existing workflows it's trying to replace.

More from this day
